Socket board - How many consumers can be connected to a socket strip? How do you integrate the power strips into office furniture? You can find out in this eibabo® catalogue, and find the right product for you from the large selection of socket strips. Socket strips are also referred to as multiple sockets or power strips. These provide a connection to the power grid for several electrical consumers with a standardized plug connection. In contrast, an extension cord usually only has a single connection.Which criteria are important for the purchase of a power strip?A power strip is a relatively simple tool for expanding the electrical installation. Nevertheless, it is advisable to pay attention to a few basic things. These are:Sufficient number of slotsStable material quality of cable, plug and socketsThe presence of surge protectionSpecification of a test mark such as the GS seal or the VDE sealAn adequate IP rating for the intended useAdditional equipment (switches, child protection and so on) How many devices can be connected to a power strip?In principle, the number plays a subordinate role. It depends on the sum of the power. Please note that under no circumstances should too many powerful consumers be connected to a socket strip. Remember that a device doesn't have to be big to require large amounts of power. You should therefore not connect high-power devices such as refrigerators, washing machines, dryers, space heaters, air conditioners or ovens to a power strip. Small consumers such as lamps, computers, entertainment devices or printers do not pose a problem. TIP:The connected loads should not exceed a combined output of around 2300W at 10A or 3600W at 16A measured at 230V mains voltage. Please make sure that you do not connect multiple socket strips in a row. Otherwise the resistance (impedance) could become too large due to the concatenation.Can socket strips also be sources of danger?As long as you are using a power strip properly, there is nothing to worry about. Pay attention to the performance of the connected devices and to a safe laying of the cable. Never lay a line under a carpet that many people walk over every day. Over time, this can cause the wires in the line to break, heat up, and cause sparks. Check the cable and the power plug of the strip regularly. If you find any damage, replace the power strip.Image: Bachmann 333.400 19 inch power stripWhat types and equipment are possible with socket strips?Combinations of different equipment features are also often available. At eibabo® you can get socket strips with switches and overvoltage protection or master/slave socket strips with switches, among other things. Further explanations would be, for example:Switch, toggle switch or foot switchtimersOvervoltage protectionchild lockMaster/slave power strips Or the following statements:19 inch power stripsALU socket stripsOutdoor sockets and garden sockets or combination plugsDesk boxes and table socketsEnergy cube (SCHUKO or up to 400V CEE)Multiple crafting barsSocket strips for IEC cold devicessocket towerssurge outlets What are the advantages of power strips with surge protection?Power strips with overvoltage protection protect connected devices from damage because voltage peaks are reduced. An upstream coarse protection in the meter cabinet and medium protection in the electrical distribution is also advisable. TIP:We recommend the use of surge protection if you supply valuable technology with the additional sockets. A surge protector has another protective element that absorbs additional current. These can be current fluctuations or voltage peaks, which could otherwise damage or destroy your connected electronics.What are master/slave power strips?Power can be saved with master/slave socket strips. An integrated electronic circuit detects whether power is flowing through the master socket. If power is present at the master socket, the slave sockets are activated. If no more current flows through the master socket, the slave sockets switch off. The typical application is a computer and its connected peripheral devices. If the computer is switched on via the master socket, monitors, scanners and printers also start. Turning off the computer also disables all other devices, avoiding going into sleep mode.What do I use 19 inch power strips for?19 inches is a standard installation size for server cabinets. If you want to install many devices in your server cabinet, you need an adequate power supply. With a 19-inch socket strip, up to 10 devices can be connected. The socket strip is adapted to the profile rail of the 19-inch server cabinet and can be mounted directly.We recommendIn order to set up additional protection, we also recommend an uninterruptible power supply (UPS) in addition to integrated overvoltage protection.You can also get high-quality UPS systems in the eibabo® shop. Use our intelligent search.What options do I have for permanent installation of power strips?You need electricity at practically every workplace. With socket strips for mounting on, under or in a desk, you can create connection points for monitors, printers, beamers and telephones. So you don't have to crawl under the desk every time you want to connect something. In addition, the connections don't get dusty as quickly because they are easy to access for cleaning or are integrated into a housing. In addition to the desired number of power connections, other interfaces (USB, HDMI and others) are often available. In addition to mounting on or under the tabletop, it is sometimes possible to retrofit it by drilling or cutting out the tabletop.With socket units you remain flexible. These are housings that you can individually equip with suitable inserts. This is how you put together the perfect supply bar yourself.  Catalogue content:In this eibabo® catalogue Domestic switching devices > Multiple socket you will find items from the following product groups:Item overview:Artisan tinComputer power stripConnection accessoriesDouble socketEnergy measurementFranceGarden socketGround spike socketMains interference filterMonitoringNetwork cabinetsNetwork connectivityNetwork interfaceNine-way socketOvervoltage protectionPlug-in modulePower distributionPower stripsPower supplyRedundancy moduleRetrofitSchuko socketSocket caseSocket coverSurge protection deviceSurge protection moduleTable socketTable socketsfrom the following manufacturers:Manufacturer overview catalogue Socket board:BachmannBrennenstuhlDehnE+P ElektrikEatonEaton USVEgloEnocHamaHartingJungKindermannLegrand BticinoOBOPentairPollmannRittalSchneider Elec.(APC)Schneider ElectricSchäfer IT-SystemsTehalitVertiv
Surge protector - electr. - Are you looking for a surge arrester for your electrical installation? But you are still not sure what requirements such a device has to meet? Then read on here. In order to understand why a surge arrester is useful, you must be aware of the dangers associated with voltage spikes or surges. Even if these events are rare and only last a few milliseconds, they can still result in major damage. We therefore always recommend a surge protector to prevent the loss or damage of sensitive electronic equipment. We will help you to choose the right item.What are surge arresters?Overvoltage protection devices are of great importance in electrical engineering. These are used to limit and divert overvoltages in electrical lines and sensitive devices such as computers, televisions or hi-fi systems. But how does overvoltage occur? The normal mains voltage in Germany is 230V. Overvoltages go well beyond this value and are caused, for example, by lightning strikes, short circuits, electrostatic discharges or switching operations by the network operator. The consequences of such an event depend on the magnitude of the overvoltage, the speed of the voltage pulse and its duration. Failure to set up protective measures can result in fire, explosion and personal injury.The surge arresters (Surge Protective Devices SPD) are installed in the distribution board or in the sub-distribution boards and connected between the active conductors and earth. Surge arresters are usually designed as pluggable modular devices or as devices for mounting on top-hat rails and some are equipped with a fault indicator. In this eibabo® catalogue, we present the devices that are used for overvoltage protection and are therefore part of the internal lightning protection of a building.Lightning protection and effective surge protectionIn order to be able to decide on a specific surge arrester, you should know the entire structure of an effective system for protection against lightning and surge voltage. Such a system usually consists of several parts. This can quickly get a little confusing. We give a small overview.Already knew?We distinguish between surge protection and lightning protection. Surge protection devices are designed to protect against damage caused by excessive voltage. Lightning protection systems, on the other hand, are intended to protect against damage caused by excessive currents.A few definitions of terms in advance:Lightning is high-energy and carries very high lightning currents. In the case of overvoltages, the currents and energy are small, but the charge difference between two potentials is very large. In order to counteract these dangers completely, such a system consists of three parts:the external lightning protectionthe internal lightning protectionthe overvoltage protection In this context, different categories and protection classes are often mentioned, which laypeople quickly confuse. These include:Lightning protection classes (I-IV)Buildings are divided into four lightning protection classes in order to be able to assess the risk of lightning strikes. The class in which a building is to be classified depends on its type, use and the damage to be expected. The lightning protection class determines the structure and dimensioning of the lightning protection system.Overvoltage Categories (I-IV)The four overvoltage categories describe the surge resistance of electronic devices. This specification therefore refers to end devices such as laptops (category I), toasters (category II), residual current circuit breakers (category III) or primary overcurrent protection devices (category IV). Look in the operating instructions of the respective device. The tolerability to power surges is low for electrical devices of category I and is 1500 volts. Category IV devices can handle up to 6000 volts.Surge Protection (Type 1, Type 2, Type 3)Surge protection devices (e.g. surge arresters) are divided into coarse protection, medium protection or fine protection. Which type a device is to be assigned to depends primarily on the voltage levels that it can absorb. This results in the respective area of application.Image: Dehn DG M TNS 275 DEHNguard surge arresterThe external lightning protectionExternal lightning protection consists of lightning conductors, lightning arrestors, earthing, fastenings and so on. Just this much: The external lightning protection intercepts direct lightning strikes before they hit the building. The high lightning current is discharged directly into the ground via the grounding system. In principle, there is no obligation to install external lightning protection systems in Germany unless your building:stands free on a mountainis over 20 meters highhas a combustible roof (e.g. made of thatch, straw)has public transport (theater, swimming pool) But even if your building does not meet any of these criteria, a lightning conductor is always useful, because the damage can be enormous in the event of a strike. You can find more information about external lightning protection, grounding and installation as well as purchasing here in the shop. Simply use the appropriate terms in the input field of our intelligent search.The internal lightning protectionThere is no denying that lightning and other surge voltages are dangerous. In order to protect apartments, houses, industrial plants and the devices and systems they contain, effective internal lightning protection and overvoltage protection is required. The internal lightning protection is a potential equalization in which all metal pipe installations and all cable installations in a house are connected to each other and to the main earthing bar. This prevents voltage differences, lightning flashovers in the building and the resulting danger to people and technology.The overvoltage protectionOvervoltage protection is part of the internal lightning protection. When choosing a suitable surge protector, we consider the nature of the potential interference and the type of equipment to be protected. How much energy does a possible overvoltage have? Which devices are particularly sensitive to voltage pulses due to their design? A current device for overvoltage protection has a three-stage structure and thus optimally protects buildings, systems and devices from damage. This includes, among other things, a combination of different surge arresters adapted to the respective requirements. definitionThe term 'transient' is rare in German usage. It means that something is temporary, fleeting and impermanent. There are different requirement classes for overvoltage protection devices. A distinction is made between Type 1 (general protection), Type 2 (medium protection) or Type 3 (fine protection). The standard devices represent the fine protection and protect against voltages up to a certain level, the extended devices offer additional protection against transient voltage peaks and the high protection standard also protects against impulse currents. But what does it exactly mean?Type 1 overvoltage protection is called a lightning arrester. This is suitable for deriving high lightning currents via the internal or external lightning protection system. The residual voltage is reduced to a level between 6000 volts and 1300 volts. These devices are ideally installed in front of the house installation so that the lightning current does not even get into the distribution. However, this basic protection is not yet sufficient to secure the end devices.Type 2 overvoltage protection represents medium protection and reduces the residual lightning voltages from the upstream lightning arresters to values between 2000 volts and 600 volts. These include the surge arresters offered in this category. These are installed, for example, in the sub-distributors of individual floors. Surge arresters also limit dangerous transient overvoltages caused by switching motors, transformers, circuit breakers or inductive loads. Disturbances of this type are short-lived, cause the voltage to rise very quickly, and can occur more frequently. The interference causes electronic devices to wear out faster.Type 3 overvoltage protection further reduces the remaining overvoltage and is installed as fine protection as close as possible to the end devices to be protected.What should you pay attention to when buying a surge arrester?You now know what parts make up a lightning protection system with overvoltage protection. Surge protection has been a mandatory part of an electrical system in Germany since December 2018 and must be installed in new buildings. Include this topic in the planning of your building or system and pay attention to high-quality components. Don't skimp on security. Retrofitting is also advisable for older buildings, because there are more and more devices with sensitive electronics in our households. When buying, pay particular attention to:mounting typeRated voltage AC/DCHighest continuous voltage for AC and DCnumber of polesprotection leveland other properties A comparison with your electrical installation and your evaluation of the protection needs of certain sensitive devices in your possession will help you to find the right surge arrester. Save hereCombination devices combine type 1, type 2 and type 3 lightning protection and surge protection in a single device. This ensures comprehensive protection in an easy-to-install manner. At eibabo you can get a large selection of surge arresters in different designs, for example as lightning arresters, residual current circuit breakers with overvoltage protection, surge controllers or as overvoltage protection devices.

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
