Through terminal - Which feed-through terminals should you use for your control cabinet? Are terminal blocks the same as feed-through blocks? Find out here what the differences are between feed-through terminals and what they are used for. In the eibabo® technology store you can get feed-through terminal blocks from all well-known manufacturers such as ABB, Eaton, Eberle, Hager, Metz, Phoenix, Schneider Electric, Siemens, Spelsberg, TE Connectivity, WAGO, Weidmüller, Wieland and Wöhner at great prices and in large quantities. We deliver our range worldwide.Feed-through terminals fulfill several functions and are among the most important components within a control cabinet. It is mounted on the DIN rail. Feed-through terminals are connecting elements between the incoming cables and lines of an installation and the actual control cabinet installation.What is the difference between feed-through terminals and terminal blocks?Feed-through terminals are terminal blocks. 'Terminal block' is a generic term that also includes other types of terminals. These include, for example, fuse terminals and relay terminals. Other terms describe the way a terminal is constructed or its ability to connect the conductors. In these contexts, one often hears about one-tier terminals, three-tier terminals, spring-loaded terminals, push-in terminals or screw terminals. We would like to briefly discuss some of these types in the following sections.Why are feed-through terminals indispensable components in the control cabinet?Feed-through terminals offer the necessary flexibility in the control cabinet to connect rigid incoming cables and lines to the relevant fuses, actuators or other devices. A direct connection without feed-through terminals does not make sense. A clear installation would not be possible. First, the cables and lines are clearly laid out on the terminal blocks. They then lead them from there to the devices in the control cabinet. As a result, the entire installation remains flexible because there are connection points and nodes for checking and changing the system structure.Image: Phoenix PT 2.5-3L feed-through terminalEach connection that is made takes on a function previously defined in the circuit diagram. The installation of the system and the function of individual connections remains traceable. This makes later additions, repairs and maintenance easier. If you want to make changes, these can be done by reconnecting individual wires. The rigid supply lines remain unaffected.And there are other advantages: For example, you can only connect two wires to many modular installation devices. The feed-through terminal blocks offer further advantages here. An example: A fuse is intended to protect several lines. However, you can only connect the cores of one line. In order to also integrate the other lines, you can create clear bridge connections on the feed-through terminals. The electrician can also carry out insulation measurements and other control work directly on the terminal blocks. Troubleshooting is made much easier and faster.What different feed-through terminals are there?Each manufacturer builds the feed-through terminals slightly differently. However, the principle is the same. There are single-level terminals and multi-level terminals. While you can only connect one line in the single-level terminal, several incoming and outgoing lines can be installed in multi-level terminals. Use a three-tier terminal for a three-wire cable. The is designed for connecting the protective conductor, the L conductor and the N conductor. This arrangement saves an enormous amount of space in the control cabinet. Three-tier terminals are mainly found in the control cabinets of private households and in smart home installations. TIP:On some models, the protective conductor has no connection point for the outgoing line. The protective earth contact is made directly by the clamp connection with the DIN rail. Another feature that distinguishes feed-through terminals is the way the wires are fastened. The screw terminal fixes the respective wire with a screw connection. This method takes a comparatively long time, especially when the plant is complex. A spring-loaded terminal makes electrical contact with a mechanical spring. This consists of a bent, flat copper contact. The wire must be inserted through a hole in the copper contact. This is only possible if the contact is clamped with a pointed tool. When the clamping tool is removed, the spring pulls back and the wire is jammed. The connection is released in the same way. The push-in connection is another fastening variant, similar to the spring-loaded terminal. Here, too, a spring presses against the wire. In contrast to the spring-cage connection, installation is tool-free and therefore even faster. The wire is inserted into the spring shaft of the feed-through terminal and the spring locks automatically. If you want to loosen the connection, you need a pointed tool. A small screwdriver is usually sufficient, which bends the retaining spring to the side and loosens the wire. This method saves a lot of time with cores with solid conductors. Wires with flexible conductors can also be attached using wire end sleeves using this method.Solid and flexible veinsYou can connect cables with solid cores and flexible strands in feed-through terminals. Both variants and combinations are permitted. Flexible cores can easily fan out. The use of ferrules makes handling easier with spring connections.The attachment of the wire using cutting terminals is rather rare. Use this variant if your veins are particularly thin. Here, the contact is made through a small cut in the insulation.Depending on the function and area of application, cables and wires with different cross-sections are used in the electrical installation. This affects the feed-through terminals. Appropriate feed-through terminals are available for all common cable cross-sections. Whether a clamp can be used for a specific cross-section is indicated on the clamp. It is usually possible to bridge the L conductor and the N conductor using several feed-through terminals, sometimes on several levels. Suitable cable bridges are available here in the shop.markLabeling the lines helps with orientation, especially when a new employee or another electrical company takes over the system. Some terminals have labeling fields. We recommend using this option and labeling all devices and connections in a meaningful way.The design of the neutral conductor contact is another distinguishing feature. In addition to models for classic wiring, there are feed-through terminals with which an N busbar can be used. The neutral contact on these terminals is designed accordingly so that the connection can be made with one hand. When using a busbar, you need an additional terminal for feeding. To securely fix the rail, use suitable support blocks or the fastening levers on the end clamps at the beginning and end of the row. Longer rails are additionally fixed every 20 cm. To be able to use cables with five cores, use multi-level terminals to connect the outer conductors.How to use feed-through terminals in the KNX area?In addition to the classic feed-through terminals, you can get special terminal blocks for low-voltage or KNX use. These have a different color and can therefore immediately be distinguished from other terminal blocks. This also contributes to order and clarity in the control cabinet. In terms of function, these terminal blocks hardly differ from conventional terminal blocks. You can connect cables with a cross-section of up to 1.5 mm2 to these terminals.Why are feed-through terminals not closed on one side?The available space in the control cabinet is specified in modular widths (HP). These provide information about the capacity of a control cabinet. Feed-through terminals are not manufactured according to this pitch, but as narrow as possible. The narrower a terminal, the more terminals can be installed on a specific area of the DIN rail. Good to know:Feed-through terminals are not closed on one side. The missing cover saves a little space. In relation to the length of a top-hat rail, more terminals can be mounted. Since feed-through terminals are mounted directly next to each other on the DIN rail, there is no danger of touching the contacts on the open sides. Without a side cover, a terminal is narrower. A cover is only attached to the last terminal in a row.Which installation aids and which accessories are available for feed-through terminal blocks?For the construction of a control cabinet, you receive numerous well thought-out components that simplify your work. For feed-through terminals, for example, the cross-bridges and busbars already mentioned are available. In addition, you will receive separator plates and end plates, covers, feeds or end blocks as well as test plugs, fuses, labeling fields and other components.  Catalogue content:In this eibabo® catalogue Terminal blocks > Feed-through terminal block you will find items from the following product groups:Item overview:Base clampBolt clampChangeover relayCompartment clampConnecting combsConnection moduleConnection technologyDistribution blockFeed terminalFour-level clampLightning arrowMarshalling boxMini clampMotor connection terminalMotor output terminalMulti-level clampMulti-wire terminalNeutral terminalPotential clampRelay terminalSocketSpring clampsSpring clipSwitching relayTerminal block connectorThermal voltage terminal blockThrough terminalUniversal clampfrom the following manufacturers:Manufacturer overview catalogue Through terminal:ABBEatonEberleHagerMetzPhoenixSchneider ElectricSiemensSpelsbergTE ConnectivityWAGOWeidmüllerWielandWöhner
Dimming actuator - The technical requirements for the use of dimming actuators are very extensive. Why do I need a dimming actuator and which dimming actuator is the right one for me? In this eibabo catalog you will find many dimming actuators from different manufacturers, for example from the top brands ABB, Berker, Busch-Jaeger, Eaton, EVN, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben various automation systems or conventional applications.How do I plan the lighting correctly?You should not start with the control technology first, because this follows at the very end of the lighting planning. First you should plan the lighting according to necessity, appearance, ambience and your own wishes, followed by the functional requirements and then find the right lights.Save by planning!The more precise, the cheaper the execution of the installations. The more complex the functional requirements are, the more important it is to plan and research a suitable SmartHome system.Only then is the functional implementation carried out, which consists of many other topics.What should I know beforehand?Which lights do I want to install?Do I want to use a conventional installation or a bus system?Should the SmartHome be wired or radio (KNX, DALI, or Zigbee radio protocols such as Hue)?Which lights are switched and/or dimmed together and how?Should it be controlled via app or voice assistant?and much more... ... this results in the following findings, for example:Which cables and lines are required?Which control components (e.g. dimming actuators) have to be considered?To what extent do the operating resources have to be secured?How much space must be provided in the electrical distribution?Do I have to consider special flush-mounted sockets for lights?and much more... What do I have to consider before buying a dimming actuator?Before you buy a KNX dimming actuator, the load types of the equipment and their performance should be checked carefully. There are basically 3 types of KNX dimming actuators. There are dimming actuators with the control type leading edge, trailing edge or universal dimming actuators that recognize the connected load type and automatically activate the correct type of control. TIP:Install a few more lights in the room and use a dimming actuator to create a pleasant lighting ambience. KNX dimming actuators are available for installation in the electrical distribution system, then they have the suffix 'REG' for modular installation devices or as a concealed version 'UP' for installation in a mounting box or junction box or as an installation version 'EB' for integration in ducts or similar. 230V halogen lamps or incandescent lamps, for example, can be operated with both types of control.What is the difference between leading edge dimming and trailing edge dimming?Very simply explained; 12V low-voltage lighting (NV) with a conventional iron-core transformer requires phase control dimming, although these transformers are hardly ever used. 12V low-voltage lighting (NV) with an electronic transformer requires trailing edge dimming.The type of dimming of the dimming actuator can be recognized by the abbreviation 'RL' for trailing edge dimming for incandescent lamps, 230 volt halogen lamps and the abbreviation 'RC' for trailing edge dimming for incandescent lamps, 230V high-voltage halogen lamps, 12V low-voltage halogen lamps, dimmable LEDs and dimmable ones energy-saving lamps. It is also possible that both abbreviations 'RC' and 'RL' can be found printed on the dimming actuator. Often you will also find this imprint: 'R, L, C'. It designates which equipment the dimming actuator can work with (dimmer, transformer, LED). If you find all 3 letters or the abbreviations 'RL' and 'RC', then it is usually a universal dimming actuator.Image: KNX LED universal dimming actuator - Jung 390041SRIn this case, however, the limit values of the power ranges for each type of dimming with connected equipment must be observed. Dimming actuators often have minimum loads, which may not be suitable for the use of LEDs. Trailing edge dimming 'RC' (trailing edge control) is the most common application. Basically, the lamp and the dimmer must be marked as 'dimmable' and fit together. TIP:For LEDs, we always recommend LED dimmers or LED controllers, which have also been developed for exactly this application. If in doubt, you can also contact the manufacturer of the dimming actuator directly if you send a data sheet for the equipment (lamps and, if applicable, ballasts).Can I dim a fluorescent lamp? Are energy-saving lamps dimmable?Yes, fluorescent lamps and energy-saving lamps can also be dimmed, provided the lamp is suitable and marked as 'dimmable' or, in the case of fluorescent lamps, there is a dimmable electronic ballast (EVG) for 1-10V or the DALI standard. You can find KNX dimming actuators for electronic ballasts with a 1-10V interface under Smart Home > Light control unit. Another standard for electronic ballasts is DALI (Digital Addressable Lighting Interface). The advantage over the 1-10V variant is that addressing is possible and there is no wiring according to groups. Further advantages are direct addressing, status messages, scene memory and a wide range of dimming options with the DALI ECG.How do I find out if my lamp / luminaire is dimmable?Basically, the light source used should first be checked to see whether it is dimmable. You can find this marking in the item description or on the packaging. Lamps that have already been planned and fitted with light sources must be checked for dimmability and the type of control with the control gear used.How do I determine the power for my dimming actuator?It must be clear which light groups are to be switched and dimmed together and how high the total output (W/VA) of the group is in order to select the appropriate KNX dimming actuator with regard to the required maximum output, the minimum load and the number of channels as well as the type of control Find. eibabo always recommends a thorough analysis of the application prior to purchase. Lamps and illuminants must be technically analyzed and checked against the technical data of the dimming actuator. In addition, there are countless different parameter properties of KNX dimming actuators between the manufacturers.Why can't I dim my LED light?All dimming actuators meet the standard requirements for dimming. In addition, many manufacturers offer additional interesting parameters. These parameters may be functionally important for your project. The marking KNX universal dimming actuator does not automatically mean that these dimming actuators are also suitable for dimming the LEDs you use.  Catalogue content:In this eibabo® catalogue Installation bus systems > Dimming actuator for bus system you will find items from the following product groups:Item overview:ActuatorBasic moduleBinary inputBrightness controlBus technologyControl blockControl unitDimmer plugDimming actuatorsDimming extensionDIN railEnergy efficientExpansion moduleFan driveFunction moduleLight controllerLightbulbsLightingLighting technologyLuminaire controlOutput moduleRadio controlRadio receiverRetrofit lampsSocket coverStarter packUniversal dimmerUniversal dimming actuatorfrom the following manufacturers:Manufacturer overview catalogue Dimming actuator:ABBBerkerBusch JaegerEatonElsoEltakoESYLUXFinderfrogblue AGGiraHagerIssendorffJungLegrand BticinoLegrand SEKOLingg & JankeMDTMean WellMertenPehaSchneider ElectricSiemensThebenWielandZumtobel
Manual wall transmitter - Manufacturers of radio bus systems for home automation systems use different radio standards (EnOcean, Z-Wave, ZigBee, Bluetooth Smart, Bluetooth, WLAN). Leading manufacturers are Eaton Eltako and Thermokon. This catalog offers wireless handheld wall transmitters for different automation systems made by different manufacturers. Radio bus systems are an alternative to building automation systems such as KNX, LON or LCN. Radio bus systems are much cheaper and the range of applications and devices differs from manufacturer to manufacturer. Therefore, one should not use proprietary radio bus systems, but a radio bus system where devices of different manufacturers are compatible, such as with the KNX. However, in radio bus applications, the scope of options is always increasing in order to meet the smart home requirements. Radio bus systems can be connected to building automation systems, for example to KNX. Thus, mixed applications are possible, for example if installations with cables and wires are not possible (glass constructions, wood surfaces, open spaces). Compared to building automation systems, it is easier to put wireless home automation systems into operation and they are cheaper, but they are also less flexible when it comes to complex functionalities and future extensions. eibabo provides battery-free wireless wall transmitters, wireless remote controls, wireless handheld transmitters, handheld KNX radio transmitters, KNX radio wall transmitters, wireless outdoor transmitter module, wireless handheld multi transmitters , KNX RF transmitters, KNX wall transmitter modules, wireless wall transmitter inserts or wireless universal transmitter radio bus from leading radio bus manufacturers such as Berker, Busch Jaeger, Eaton, Elso, Eltako, eQ-3, Gira, Hager, JUNG, Peha, Schalk, Siemens and Thermokon.Catalogue content:In this eibabo® catalogue Installation bus systems > Hand-/wall sensor for bus system you will find items from the following product groups:Item overview:Bus system handheld/wall transmitterBus system wall transmitterBus technologyDouble asterEnd stripsHand-/wall sensor for bus systemInstallation switchManual transmitterMoellerfunkPosition buttonQuad buttonRadio button interfaceRadio remote controlRadio systemRadio transmitterRadio wall transmitter insertRemote controlSingle buttonSolar cellSurface-mounted buttonTransmitter insertTransmitter useTransponderWall transmitterWall transmitter completeWall transmitter insertWall-mounted transmitter completeWall-mounted transmitter insertfrom the following manufacturers:Manufacturer overview catalogue Manual wall transmitter:BerkerBusch JaegerEatonElsoeQ-3GiraHagerJungPehaSchalkSiemens

Choose from numerous different versions for a wide range of applications. Best prices, a wide range of additional information and illustrations, fast availability and worldwide shipping characterize our shop. In addition to the company Wago, other well-known manufacturers offer high-quality plug-in terminals. The eibabo® shop stocks plug-in terminals from the brands ABN, Barthelme, Eaton, Finder, Hager, Hellermann Tyton, Kleinhuis, OBO, Phoenix, PROTEC.class, Spelsberg and Striebel & John.You will find a large selection of clamps for different requirements and areas of application. There is a large number of terminals, which are designed in different designs depending on the wire type and cross-section and thus perfectly match the respective area of application. These include bus coupler terminals, compact connection terminals, box terminals, terminal strips and connection terminals. Depending on the design and area of application, the plug-in terminals have a certain number of slots. Some variants of clamps are transparent. This will help you see if the wire is properly attached.Image: WAGO 243-208 screwless connection terminalWhat are plug-in terminals?Plug-in terminals is the name for numerous different spring-loaded terminals, spring-loaded terminals, connecting terminals or screw terminals. These are used in electrical engineering to connect wires, cores and lines. Clamping or screwing an electrical conductor offers a safe and maintenance-free connection. Already knew?Push-in terminal does not mean that the wire is fixed by inserting it into the terminal. There are also push-in terminals where the wire is held in place with a screw. The plug-in terminal is also often referred to as a Wago terminal. The clamps were given this designation after the manufacturer Wago. He introduced the spring clamp technology in the early 1950s and has continuously improved it since then. Since the 1970s, the product has revolutionized electrical installation, as screw connections can now be dispensed with in many areas. However, this does not mean that clamps with screw fastening are no longer used. In this catalog you will also find clamps with screw connections, also known as luster clamps or Euroclamps.Where are plug-in terminals used?Push-in terminals are one of the most popular methods of making electrical connections. Solid or stranded conductors can be connected quickly and safely with the help of plug-in terminals. In our shop we offer different types of clamps, which are suitable for different areas of application. For example, there are terminals for use in the following branches of industry:electrical industryautomotive industrytelecommunicationscommunications engineeringPlant construction and mechanical engineeringcomputer engineeringmedical technology In the private sphere, plug-in terminals are mainly used to clamp rigid wires in junction boxes, in control cabinets, in domestic installations or to connect lights.What should I know about plug-in terminals before buying?Electrical installations and electronic circuits almost always have to be connected to external devices, power sources, inputs or outputs. These connections are made using plug-in terminals. These are available in many different types, shapes, sizes and denominations. Choosing unsuitable plug-in terminals can cause some difficulties. These can be simple space problems within a terminal box or have serious consequences such as fires. Therefore, we would like to introduce you to some types of plug-in terminals. Although there are many other variants, we limit ourselves to the most well-known products, which can be found in almost every sector. The areas of application range from classic household wiring to automated applications.Push-in terminalsSo-called push-in terminals use small spring-loaded contact levers. The highlight is that the electrical conductor can be pushed into the terminal without tools. However, it is not possible to pull it out just as easily. The wire is effectively held in place. Compared to the screw clamp, this fixing method offers the advantage that the wire cannot be damaged during installation. If you want to release a pinched wire, pull on the wire while making an alternating twisting motion. In this way, you release the plug connection without damaging the plug-in terminal, the spring mechanism or the electrical conductor.Please noteNot all push-in terminals are designed for multiple use. Some clamp springs hold the wire 'forever'. If you want flexibility in your installation for modifications or repairs, choose push-in clamps with a lever-release lever. This releases the wire again when actuated.When choosing the right terminal, pay attention to the appropriate cable cross-section. This should always correspond to the permitted nominal cross-section of the terminal. You will typically find this information on the packaging. An electrical conductor that is too thin cannot be securely clamped and held.terminal blocks and terminal blocksTerminal blocks accept a single wire and connect it to a circuit or other system. Terminal blocks are available in a variety of sizes, ratings and shapes and are available in rows. Each terminal in a row is only fitted with one wire. This variant of the plug-in terminal is useful for connections that are subject to regular maintenance, repair or modification. Terminal blocks always have a mechanically strong body made of plastic or another insulating material. In addition to the spring attachment, versions with a locking lever are also available. The wire is inserted and a clamping lever holds the electrical conductor in place. Another common connection method is to use a screw. TIP:Great care must be taken when tightening the screw. Overtightening the inserted cable can damage the electrical conductor. An unreliable or potentially dangerous connection would result. In some variants, the screw presses the electrical conductor against a metal body. On other screw-connection terminal blocks, the screw presses onto a flat metal head. This in turn presses the wire against a metal insert.Pluggable terminalsPluggable terminals have a cable entry to allow the wire to be connected. On the other hand, these terminals have a plug output and thus offer a pluggable connection for further installation. This type of plug-in terminal is useful when the connection must be frequently disconnected for maintenance or inspection. These contacts are usually screwed.barrier clampsBarrier clamps also use screws as the mechanism for holding the electrical conductors. Barrier clamps often have more than one connection point for multiple cables or wires. These connection points are isolated from each other (barrier). Depending on the model, barrier terminals have small covers or housings. These protect the cabling additionally. Barrier clamps find application in house wiring and other high voltage connections where arcing or potential short circuits must be avoided.  Catalogue content:In this eibabo® catalogue Installation, isolation and connection material > Screw less terminal you will find items from the following product groups:Item overview:Apartment distributorCable connectionCan clampClamp adapterClamping railComplete cabinetConnection clampConnection clampsConnectorConnector pinsCounter distributionCounter systemDirect measurementEngineering centerFuse boxFuse distributorJunction box clampJunction box terminalMeter boxNeutral terminal barOverhead line clampPower boxRelaxation gripSix-wire terminalSmall distributorsSpare PartsTerminal blockTwo-wire terminalfrom the following manufacturers:Manufacturer overview catalogue Plug-in terminal:ABNBarthelmeEatonFinderHagerKleinhuisOBOPhoenixSpelsbergStriebel & JohnWAGO
Frequency converter = - Do you have an AC motor and want to control its speed? Then the use of a frequency converter is an interesting product for you. A frequency converter is always used when you need permanent speed control on a machine. This can be, for example, pumps or compressors, but also fans, mixers or mills with electric motors. A frequency converter converts the fixed mains voltage into a variable voltage. This enables not only operation of the motor at a constant speed, but also acceleration and deceleration. In this way, the speed of a machine can be adapted to the current work requirements, energy can be saved if necessary, or production processes can be varied over time.Use the high-quality frequency converters from the eibabo® shop, protect materials with speed control and thereby extend the service life of your machines. Manufacturers of high quality goods are ABB, Eaton, KEB Automation, Maico, Mitsubishi, Omron, Rockwell, Schneider Electric and Siemens.What is electrical frequency?In order to explain electrical frequency and to be able to deduce the function of a frequency converter, we must first look at the basics of electricity generation. There is direct current and alternating current. Direct current always flows in one direction. Alternating current periodically changes direction. This change is represented in a diagram in the form of a sine wave, which is alternately in the positive and negative area of the zero point. Accordingly, an alternating voltage is also an oscillating electrical voltage.Already knew?The Danish company Danfoss was the first company to start series production of frequency converters. This was in 1968.The AC frequency describes the number of cycles in this sine wave per second and corresponds to the number of changes in direction. This is given in Hertz (Hz). 1 Hertz corresponds to a complete cycle from the zero point to the positive range, to the negative range and back to the zero point. The more cycles per second occur, the higher the frequency. The usual mains electricity in Germany and Europe has a fixed frequency of 50 Hertz.How does a frequency converter cause a change in motor speed?The standard speed of an AC motor is tuned to a specific frequency. This is based on the structure of the respective motor. A constant magnetic field with stationary poles prevails between two field magnets. Within this magnetic field is a rotating, also magnetic 'anchor' with two poles. If alternating current is passed through the armature, its polarization changes in time with the alternating current. With a mains frequency of 50 Hz, this happens 50 times per second. Accordingly, the attractive and repulsive forces between the field magnet and the armature change direction 50 times. Once set in motion, this alternation ensures a certain rotational movement of the armature and speed of the motor. Each change in frequency therefore also causes a proportional change in motor speed. The frequency converter is responsible for changing the frequency.The advantages are:infinitely variable control of the desired nominal speedReach very high and very low speedsdirect switching of the direction of rotation Picture: Schneider Electric ATV320U22N4C frequency converterWhat are the reasons for a change in engine speed?An almost constant frequency is applied to the classic AC network and therefore only one speed is available to you. The frequency converter regulates the frequency and voltage of the power supplied to the motor. That is why this device is often also called a speed controller. There are many reasons why the engine speed needs to be adjusted:to save energy and increase efficiencyto optimize the flow of manufacturing processesto protect material and extend the service life of machinesto meet the requirements of processing various materialsto adjust the torque / power of a driveto lower the noise levelto reduce peak loads Modern frequency converters have network and diagnostic functions. This makes it possible to integrate the devices into the control system of a plant and to monitor and optimize all processes.Where are frequency converters used?Frequency converters are used in numerous industries and applications. These devices are mainly found in compressor, pump and fan drives. But the speed of conveyor belts, production lines or cranes can also be controlled with frequency converters. An adapted or infinitely variable speed enables energy-efficient and optimized production processes.What should be considered when buying a frequency converter?The correct selection of the frequency converter is crucial for the optimal operation of the corresponding devices. Before selecting the drive, determine the number of input phases. Will the device be three phase or single phase? Will the device handle resistive loads, inductive loads, capacitive loads, or mixed loads? The individual loads cause different inrush currents when starting. Please consider this. Before you buy, find out about:the requirements of the operating environmentthe starting torquethe load torque characteristicsthe speed control range and the static speed accuracy  TIP:You are very flexible with regard to the location. Frequency converters are available for installation in the control cabinet, for wall mounting and for decentralized field use. Since a certain level of expertise is required to evaluate these properties, we recommend consulting an experienced electrician.  Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Frequency converter =< 1 kV you will find items from the following product groups:Item overview:Built-in converterConverter unitDrive amplifierEngine controlEngine outputFan controlFan speed controllerFrequency controllerFrequency converterMotor controllerPump converterServo amplifierServo converterServo driveSpeed controllerSpeed settingVariable speed starterfrom the following manufacturers:Manufacturer overview catalogue Frequency converter =
Residual current circuit breaker - Why should you never do without a residual current circuit breaker in your installations? And how do you find the right device with the best price-performance ratio? Interesting information about the function and use can be found on this page. Notice:Working with electricity is always dangerous. Always have electrical installations carried out by a specialist electrical company. If you're unsure as a layperson, be sure to invest in professional support. This way you get a working installation and can rely on the installer's warranty if necessary.What is a residual current circuit breaker?Residual current circuit breakers, also known as residual current circuit breakers, bear the official designation RCCB. This is an abbreviation for 'residual current operated circuit breaker' and the devices belong to the superordinate group of 'residual current devices' (RCD), i.e. residual current protective devices. Residual current circuit breakers prevent dangerously high residual currents against earth and thus help to prevent life-threatening electrical accidents in low-voltage networks. These are connected upstream of the overcurrent protection devices in circuit distributors.At eibabo® you will find not only a large selection of residual current circuit breakers, but also other protective devices such as residual current protective adapters, residual current protective plugs, automatic circuit breakers and automatic personal protection.Is an RCD and an RCCB the same thing?In colloquial German, the term 'FI switch' is still very common. The 'F' stands for error and the 'I' for the symbol for the current strength. Ultimately, it's just another name for the same device.Picture: Eaton PXF-25/2/003-A residual current circuit breakerHow does a residual current circuit breaker work?The device builds up a magnetic field around the incoming currents. This is neutralized by the currents flowing back. In error-free normal operation, this creates a balance between the energies within the system, which ensures that a relay can let the current flow unhindered. If a fault current occurs, it will create an imbalance, causing the voltage to drop across the relay and its auxiliary contacts to break the circuit. As a result, the switch shuts down the system within tenths of a second without auxiliary power.Is the use of a residual current circuit breaker mandatory?It all depends on which country you are in. There are national regulations for this. In Great Britain, the simpler and smaller electronic residual current circuit breakers are currently still common. In principle, however, the use of these devices is mandatory in many countries for new installations, modernizations or far-reaching changes for private households, commercial units and industrial plants in addition to the installed overcurrent protection devices.In Germany, this applies, for example, to socket circuits up to 32 A and lighting circuits in apartments as well as for commercial buildings, schools and training centers, baths and swimming pools as well as fire-prone business premises and systems. Notice:Old systems that corresponded to the applicable standards at the time of their construction usually have grandfathering. You may continue to operate, maintain and repair them, but not fundamentally expand or change them.i have backups Can I then do without the residual current circuit breaker?Irrespective of the fact that residual current circuit breakers are necessary for the technical acceptance of the system, they fulfill a different task compared to normal fuses and cannot be omitted. Normal home fuses are also known as circuit breakers. Their function can already be derived from this. They protect power lines from short circuits. They interrupt the circuit even at higher currents and imminent overload. This prevents cable fires, for example.Residual current circuit breakers, on the other hand, have the primary task of protecting people and switching them off as quickly as possible, for example if people touch the damaged part of a live line. Because that can be life-threatening. The switch is also used for fire protection. Small fault currents that do not trigger a normal house fuse are prevented.Which type of residual current circuit breaker is the right one for end users?There are very different models on the market, each with individual characteristics. A basic distinction is made between types A, A-EV, AC, B, B+, F and S. Type A is the most common variant for use in classic households, in commerce, in public facilities, functional buildings and industrial plants. This is a pulsating current-sensitive switch that detects alternating currents and pulsating DC residual currents. The value at which the switch should trip is 30 mA (milliamps) in normal use. It is therefore necessary to install a switch with a rated fault current of 30 mA.Rated current and rated residual current ? what is the difference?Both key figures are crucial for choosing the right circuit breaker. The rated current is the maximum voltage that can be conducted via the residual current circuit breaker per phase conductor. The rated residual current describes the maximum measured difference between incoming and outgoing currents before a residual current circuit breaker has to trip at the latest.AssemblyA residual current circuit breaker is typically installed in the meter cabinet / electrical distribution box. The position is directly behind the electricity meter and in front of the classic circuit breakers.The switch thus covers all circuits in a system, regardless of whether they are inside a building or outside. However, it is advisable to use several separate residual current circuit breakers and fuses depending on use. In many countries and regions it is even mandatory to equip special areas with their own residual current circuit breaker.Interesting - short and sweetAre additional protective measures possible?If you want to further increase the scope of protection of your electrical installation, you can equip personal protection sockets or socket strips with a residual current circuit breaker with a rated residual current of 10mA to 30mA. What additional protection do residual current circuit breakers offer?The special properties of residual current circuit breakers include personal protection against life-threatening currents and protection against fires that can be caused by earth fault currents, for example. How do residual current circuit breakers work?Due to the low tripping currents of 10mA to 500mA, the use of residual current circuit breakers means that the currents at the fault location are not as high. Are there performance differences in residual current circuit breakers?You can get the devices here in the shop in different versions: 16 A, 25 A, 40 A, 63 A and 100 A (ampere). The ampere rating of the device indicates the nominal current for which the residual current circuit breaker is designed and, along with the selection of the triggering rated residual current, represents one of the most important parameters in the purchase decision. Who Makes Reliable RCDs?We only carry high-quality devices from well-known manufacturers such as Siemens, ABB Stotz S&J, Doepke, Schneider Electric and Eaton (Moeller), Jung, Hager and ABL Sursum. Good to knowWhen choosing a residual current circuit breaker, please take its dimensioning into account. The circuit breaker must never be designed smaller than the upstream fuse, otherwise it will be overloaded.By the way: The forerunner of modern residual current circuit breakers is a German development from 1903. The principle of residual current protection goes back to a development by Sigmund Schuckert from Nuremberg, who had a corresponding device patented under the name summation current circuit for earth fault detection. The technology was then continuously further developed and in 1957 the Austrian Gottfried Biegelmeier presented the residual current circuit breaker in its current form.What effect does charging an electric car have on the residual current circuit breaker?Usually the purchase of an electric car has no effect on the circuit breaker. Nevertheless, care must be taken to ensure that protection against DC residual current is guaranteed during multi-phase charging. A type A circuit breaker does not offer such protection, but don't worry: plug-in hybrid vehicles typically charge in a single phase and are therefore technically hardly different from other household appliances. Pure electric cars that are capable of multi-phase charging cannot be connected directly to the house voltage. This requires either a wall box or at least a mobile charging cable with charging control, which then connects to a conventional 16A or 32A CEE socket. In both cases, the control unit of the charging technology should have a corresponding integrated DC fault current detection (DC fault protection). With professional installation of the wall box or the CEE socket, a simple type A residual current circuit breaker is sufficient in addition to the corresponding miniature circuit breaker.  Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Residual current circuit breaker (RCCB) you will find items from the following product groups:Item overview:Adapter plugCircuit breakerDifferential currentEarth leakage circuit breakerElectric charging stationHeat pump systemsIntermediate switchMain residual current circuit breakerPersonal protection machineRail mounted devicesRCCBResidual Current DeviceARCCBResidual Current DeviceBRCCBResidual Current DeviceFRCD switchResidual currentResidual current adapterSafety switchfrom the following manufacturers:Manufacturer overview catalogue Residual current circuit breaker:ABBBachmannBerkerDoepkeEatonGiraHagerJungSchneider ElectricSiemens
