Wöhner - We are all aware that electrical energy is one of the foundations of our modern civilization. It is the motor for prosperity and quality of life, progress, innovations and culture. Many companies are therefore developing trend-setting solutions for the electrotechnical market, aligning products with new requirements and ensuring that the available energy is used as efficiently as possible. Wöhner GmbH & Co. KG is such an electrical engineering company. It has established itself as a specialist for international fuse and busbar systems, which are mainly used in the areas of energy distribution, control technology and renewable energies. The company headquarters are located in the Bavarian Rödental. The group of companies consists of more than 10 subsidiaries and a nationwide network of agencies in over 80 countries at home and abroad. However, research, quality assurance and production still take place in Germany and thus bear the title "Made in Germany". The company has existed since 1929 and was founded as a small assembly company for electrotechnical installation material. A feeling for details combined with inventive talent has led to more than 100 patents over the years and to the continuous expansion of the product range. The eibabo® shops from eibmarkt® have been sales partners of Wöhner GmbH for many years and regularly recommend the high-quality components to their customers and partners. These include, for example, connection terminals, busbar supports, expansion terminals, switch disconnectors, fuse bases, busbar adapters, covers, fitting sleeve and fitting ring keys, connectors and fuses. Experience has shown that the company maintains exemplary production and delivery logistics. This means that most items in the eibabo® technology store are in stock and can be delivered worldwide at short notice.

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
Load break switches - Do you want to disconnect circuits safely under load? Then you need a switch disconnector. But what do you have to pay attention to when buying a load-break switch? Switch disconnectors are available in many different versions. We give you an overview of the different models and help you to make the right purchase decision.What are switch disconnectors?Under normal conditions, load switches can switch and carry specified currents. Disconnectors, on the other hand, have a higher dielectric strength and lower leakage currents in the isolating distance. The switches must under no circumstances switch themselves back on automatically as a result of environmental influences and must have a clear indication of the off position. In a load-break switch, the functions of a load switch are combined with those of a disconnector. So it is a combination of both. The device protects, switches and separates with a safe isolating distance. This means that a load-break switch can also be used to reliably disconnect or switch a circuit under load up to the respective rated current. In general, we distinguish between three types of switch disconnectors:The classic switch disconnectorClassic switch disconnectors are designed for easy disconnection of a system and are used, for example, as a main switch, emergency stop switch or as a repair switch / maintenance switch. These devices are suitable for frequent switching. In the eibabo® shop you can get products for standard applications, for high-performance applications and for remote controls. In addition, we offer standard infrastructure devices for mounting on DIN rails. Please note that with all these devices, the supply line must always be fused separately.Fuse switch-disconnectorThe fuse switch disconnector combines disconnection with a fuse in one device. With this device, the fuse is cut out when switching. This means: When disconnecting under load, a visible arc occurs. Fuse switch-disconnectors are intended for infrequent switching and are used in industry as main switches or in main power distribution. definitionIn electrical engineering, the term 'isolation' refers to the all-round disconnection (of a part) of a system from all non-earthed lines. Load-break switch with fuseSwitch-disconnectors with a fuse also combine the switching function with a fuse in one device. However, the fuse is activated when the device is switched off. This enables you to safely replace the fuse when it is disconnected. The devices are also designed for frequent switching and are therefore also suitable for high-power applications, as main switches and in the main power distribution.What do I use a switch disconnector for?Load-break switches protect people and machines and are used for:Activation of resourcesSwitching short-circuit currentspower shiftingProtection against overcurrentProtection against electric shock These can be used as the main disconnect device in switchgear, interrupting the power supply to one or more electrical circuits. It is possible to switch or disconnect the circuits even under load up to the level of the respective rated current. With a load-break switch, you separate electrical devices, for example for maintenance work and repair purposes. The aim of the switch is to safely stop the flow of current in order to enable authorized specialist personnel to work safely. It does not matter whether it is a simple or a complex installation. Load-break switches offer ideal performance characteristics for industrial use as on/off switches, main switches, motor switches, control switches, repair switches, emergency stop switches and much more. The function as an isolating switch and load switch makes these devices very economical, especially in small systems, because the use of additional isolating switches is not necessary.Image: Hager HAB406 switch-disconnectorWhat is the difference between a classic switch disconnector and circuit breaker?Switch disconnectors and circuit breakers perform different tasks. The switch-disconnector works with the simple objective. to disconnect the power supply. This allows electricians to carry out their maintenance work, repairs and inspections safely. A circuit breaker can take on more tasks than a load-break switch. A circuit breaker connects, carries and interrupts current under standard switching conditions. This is well suited to perform the duties of a disconnector or load switch. Like the load-break switch, it offers full disconnection if required. You can use the circuit breaker as a protective device because it can control the flow of current like a fuse. The device breaks the circuit under unfavorable conditions such as overload and short circuit. A load-break switch does not offer these advantages. Depending on the model, you can control a circuit breaker manually or automatically.Conclusion: A load-break switch serves as a disconnecting device to completely stop the flow of power and is often associated with a circuit breaker or a load switch. The circuit breaker works as a switching device to interrupt the short-circuit current and the rated current. To ensure maximum security, both devices usually complement each other.How do switch-disconnectors ensure safe disconnection of the current flow?Shifting under load is a special process. Sparks and arcs can occur when two conductive contacts are separated. These allow the current to continue to flow, although the contacts are no longer touching. With small currents, a sufficiently large distance between the contacts prevents the sparks from 'jumping over'. These go out by themselves without making a new electrical connection. If this distance is too small compared to the applied voltage or if the contacts are insufficiently insulated, arcs can form.Electric arcAn arc occurs when there is a high electrical charge difference between two poles. To compensate for this imbalance, a channel forms between the poles. Inside, gas (e.g. air) is ionized and a plasma is created. The current can flow through this plasma channel.These arcs must be extinguished using special protective devices in the switch. Load-break switches and circuit breakers are therefore equipped with specific extinguishing agents in order to stop the energy flow of the arc in good time. Depending on the type of circuit breaker, these are air, oil, insulating gas or vacuum. Special chambers for deionization (arc quenching chambers) are typically used in switch-disconnectors in the low-voltage range. These artificially lengthen the arc until the voltage required to maintain it becomes too great. The arc breaks off and quenching plates prevent it from igniting again.Which switch-disconnectors are recommended?Depending on which requirements you want to meet, your eibabo® online shop offers you the right load switch, disconnector or circuit breaker.

Trunk line terminal - Would you like to create an electrical installation for a building in order to be able to set up different circuits in it? The basis for this is an efficient main line, which represents the starting point of your planned building supply. Therefore, it is typically dimensioned more heavily, the conductors have a larger cross-section. With the main line clamp, you pick up this line and provide connection options for the subsequent branches. Many main line terminals are usually safe to touch and can be mounted on classic DIN rails for quick assembly. With the inexpensive main line clamps from your eibabo online shop, you create the basis for the electrical installation of the whole house. Other branch terminals as well as cables and wires, fuses and switches can be found in the electrical material section or use our internal shop search.Catalogue content:In this eibabo® catalogue Energy distribution systems > Rail terminal bar you will find items from the following product groups:Item overview:Accessories for add-on distributorsClampClamping railClamping rail blockClipConnection clampConnection railConnection terminalDisconnect clampEarthing rail for distribution boardLine clampMain line branch clampMain line clampN and PE railN railN/PE railNeutral busbarPE and N terminalsPE clampPE clamping railPE railPE terminal railPE+N terminal railPE/N terminalPE/N terminal railRail terminal barTerminal blockTouch-safe main line branch terminalfrom the following manufacturers:Manufacturer overview catalogue Trunk line terminal:ABBABNEatonEricoFTG GöhringerHagerHenselKleinhuisLegrand BticinoMersenOBOPhoenixPollmannPROTEC.classSchneider ElectricSiemensSpelsbergStriebel & JohnWöhner
Fuse switch disconnectors - In the field of low-voltage switching devices, eibabo offers a wide range of fuse switch disconnectors for the electric distribution. Fuse switch disconnectors combine protection of plant components with switching capability under load and under overload. Thus, fuse switch disconnectors meet the requirements of a load switch as well as the requirements of a circuit breaker. In medium-voltage distribution systems, load break switches are used as main and transfer switches. When using fuse switch disconnectors, no separate disconnectors are needed which makes the use of fuse switch disconnectors particularly important for smaller switchboards. Load break switches are used for switching load-free and loaded transformers, cables and overhead power lines as well as reactive current compensation capacitors. In addition, fuse switch disconnectors are used to increase the safety in circuits, here they replace the simple disconnectors. If fuse switch disconnectors with integrated high-power fuses are used, they can also be applied in networks with higher short-circuit power. In conventional low-voltage networks fuse switch disconnectors are used for interrupting main circuits in the main distribution.Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Fuse switch disconnector you will find items from the following product groups:Item overview:Busbar mounting devicesCapsule fuseCircuit breakerConfiguratorCurrent measurementDistribution switchEMERGENCY STOP switch (load switch)Fuse holderFuse insertFuse switch disconnectorFusesKey switch (load switch)Load switchLoad switch with fuseLoad switch without fuseLoad switch/switch-disconnector with/without fuseLoad-break switch with fuseMain switchNH bus-mount fuse switch-disconnectorNH fuse switch disconnectorNH fuse switch disconnector stripProtection switch disconnector housingRider fuseSafety switchSwitchSwitch disconnectorSwitch-disconnectorSwitch-disconnector without fusefrom the following manufacturers:Manufacturer overview catalogue Fuse switch disconnectors:ABBABNEatonEfenETAGSABHagerHenselMersenMüllerRittalRockwellSchneider ElectricSiemensSpelsbergStriebel & JohnWöhner
D-type fuse base - Fuses are important to protect electrical systems from faults. Depending on the need and application, different security systems are available on the market and of course also here in the eibabo online shop. Screw fuse systems, for example, consist of several components, namely the fuse base, a fitted insert, the fusible link and a screw cap. The conductor coming from the mains and the outgoing conductor are connected to the fuse base. A fitting insert ensures that only the right fuse fits into the socket. The fusible unit itself is considered by most people to be the actual fuse and is effectively the replaceable breaking point of the circuit in question. During assembly, it is first inserted into the screw cap and screwed together with it into the fuse base. Please make sure that the current-carrying conductor is always connected to the foot contact of the fuse base. This means that accidental touching and the associated electric shocks when checking or changing the fuse link can be ruled out.Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > D0-system fuse base you will find items from the following product groups:Item overview:Busbar baseCapsule fuseCeramic baseCeramic fuse baseCopper railD0 fuse baseD0 fuse socketD0 tab fuse baseD0-system fuse baseD01 socketD02 socketD03 socketFuse basesFuse elementFuse holderFuse link clipFuse link retaining springFuse retaining springFuse socketMolded fuse baseNeozed elementNeozed fuse basePlastic basePlastic fuse socketPower distributionRetaining springRider securing elementSpare Partsfrom the following manufacturers:Manufacturer overview catalogue D-type fuse base:ABBABNEatonHagerHenselMersenRittalSchneider ElectricSiemensStriebel & JohnWöhner
