Installation small distributor - Do you need one or more small installation distributors at top conditions for the production of your electrical installation? The eibabo technology store offers the right machine housing for every requirement. Choose from numerous models in different sizes and for every type of installation. TIP:Calculate reserves, at least 25% additional space required. Size the distributor slightly larger. You never know if and when you might want to make more installs. If there is later a need for expansion, additional slots and mounting locations for fuses, sockets or measuring devices are required.What are installation small distributors?A small installation distribution board is also referred to as a machine housing, power box or fuse box. There are power distributors in almost every electrified house these days. Depending on how complex a system is, there can be various sub-distributors or group distributors in addition to a main control cabinet. The safety devices, switching devices or measuring devices for a specific section of the installation are then located in these distribution boxes.What is the function of a small installation distribution board?A complex electrical installation must be divided into individual sections. These are individually insured. This avoids faults and short circuits affecting the entire system. Such a section can be, for example, an apartment. The small installation distribution board contains switches, automatic circuit breakers and other devices with which the electrical current is distributed and secured in the respective section. From here, the lines lead to other sub-distributors (e.g. circuit junction boxes) or directly to consumers such as sockets or lamps. Devices with high power consumption, such as electric stoves, have a separate fuse in the sub-distribution board for safety reasons. The importance of an individual distributor depends on the size of the overall system. In larger houses with multiple entrances and residential units, sub-distributors may be required for each entrance, then for each floor and then for each individual apartment.Already knew?A main distribution is the first distribution after the transformer station. From here, the energy is distributed to commercial buildings, residential buildings and other consumers.Thus everything after the main distribution is a sub-distribution, field distribution or group distribution. Please refer to the product descriptions for the specifications for using the small distributors (for example: maximum rated current, number of modular units).Why do I need a small installation distributor?Electrical systems within a building are based on a primary sub-distribution. How useful a further sub-distribution is depends on the complexity of the system. Each installation small distributor thus serves as a node for a specific section. This results in the following advantages:Overview and control of the subsequent installationFrom this point it is easy to determine individual rooms. Possible errors and defects can be localized quickly. In addition, individual devices such as electric stoves or heating controls can be precisely assigned. Ensuring short cable routes to the end user or to the next fuseShort distances mean less voltage losses and line losses. Installation costs are lower. Maintenance work and repairs do not take that much time. Possibility of individually securing or switching off an areaThe installation after the distributor is secured separately. In the event of a problem or damage, only this area is affected without affecting the entire system. Picture: Hensel Mi 1444 machine housing 48TEIs the structure of a small installation distribution board standardized?A small installation distributor is a component of the electrical installation and is subject to certain regulations and standards. In Germany, these are regulated in the DIN standard 43880. The size of a junction box can be freely selected to a certain extent and is determined by your needs. The internal structure is determined by the DIN rails on which circuit breakers, circuit breakers, sockets and other devices are mounted. The top-hat rails must be at least 150 mm apart in height. This distance may be increased in increments of 25mm if required by the installation. The DIN rail, also known as the mounting rail, is divided into 12 modules. A pitch unit is indicated in the descriptions with 'TE' and is 18 mm wide as standard. This allows the capacity of an installation small distribution board to be clearly described. TIP:The external dimensions of a distributor vary from manufacturer to manufacturer. These say nothing about how many devices you can install. The capacity of a distributor is specified in division units. An example: If the description says 48TE 4x12x18mm IP54, you know that this distributor has 4 DIN rails. Each rail comprises 12 pitch units of 18 mm. The sum of the devices that you can install is 48 TE. The manufacturers follow this grid dimension and offer their modular installation devices in 1 HP, 2 HP, 3 HP and so on. The specification IP54 refers to the degree of protection. This describes how well the distributor is protected against the ingress of water or other foreign bodies from the outside. The first digit stands for foreign bodies and touch, the second digit for water. In the example given, the '5' means protection against dust and larger particles, the '4' means protection against splash water.Which devices may be installed in a small installation distribution board?The lines of the individual circuits come together in the small distributor. Here you can find the following built-in devices:Miniature circuit breakers and RCDs/residual current circuit breakers and other switchesAutomatic circuit breakers and fusesrelays and contactorstransformersStaircase light machinestimersindicator lightsSchuko socketsterminal blockstransducerOvervoltage protectionprogrammable logic controllersautomation componentsIn addition, a combined installation with the electricity meter is possible. Where and how can small distribution boards be installed?A suitable installation location must be selected depending on the function performed by the distributor. The installation can be flush-mounted or surface-mounted. Flush-mounted distributors, for example, are the first choice for masonry. Surface mounting makes sense on concrete walls. A place in the house connection room should be provided for a main sub-distribution. There are usually other media such as gas and water. For additional sub-distributions on the floors or in the apartments, observe the following installation criteria:Choose a suitable place with average room temperature.Avoid high humidity and strong temperature fluctuations.Install the small distribution board at a comfortable height. The distance from the floor to the center of the distributor should be at least 1.10 m and maximum 1.85 m.Ensure there is sufficient light and freedom of movement in and around the small distribution board.Make sure that the distributor is always easily accessible. This facilitates access to the installation if necessary.   Catalogue content:In this eibabo® catalogue Distribution boards > Small distribution board you will find items from the following product groups:Item overview:Arrester housingAutomatic installation unitBusbar systemCable holderClick technologyCombination distributorConfiguratorConnection housingDistribution cabinetEmpty CaseEmpty closetInstallation small distribution boardInsulating distributorMedia distributorMicroperforatedMistral spreaderMultimedia distributorPolycarbonatePower distributionProject delivery formRenovationSealableSingle housingSmall surface-mounted distributorSpace unitsSub-distributionTelecom fieldWall boxfrom the following manufacturers:Manufacturer overview catalogue Installation small distributor:ABNAcomeDehnEatonGSABHagerHenselHomewayLegrand BticinoNiedaxOBORittalSchneider ElectricSiemensSpelsbergStriebel & JohnTehalitTelevesWaltherWeidmüller
Switch cabinet empty - You still don't know which control cabinet to buy? You are not sure about the choice of size, materials and equipment? You will find the right control cabinet for your needs in this eibabo® catalogue. The control cabinet is the heart of an electrical installation. This is where all wires 'literally' come together.What is a switch cabinet?The control cabinet is a protected storage place for electrical devices and switchgear. This serves to ensure the safety of the devices and the people who work with them. A control cabinet contains, among other things, circuit breakers, fuses, relays, measuring devices and control devices. In addition, electricity meters, multimedia connections or power supplies can be installed in them. Control cabinets are usually differentiated according to design, size and function. The area of application of a control cabinet is often determined by its IP protection class (ingress protection). This indicates how well a control cabinet is protected against foreign objects and moisture. Most control cabinets are made of metal or plastic. Metal control cabinets are the best choice when it comes to security. Plastic cabinets are less robust and more likely to be damaged in the event of a fire. These are preferably used as terminal housings / terminal boxes for sub-distributions.What are the differences between the individual control cabinets?Control cabinets differ primarily in their design and location. Floor-standing control cabinets are designed for installation on the floor. They have a high load capacity and are ideal for heavy installations. Most floor-standing control cabinets have a double floor to ensure optimal ventilation. Wall switch cabinets are mounted on the wall or recessed from the floor to the middle between 1.10 m and 1.85 m. You will often find add-on control cabinets in server rooms. These are designed to be mounted side by side. Cabinets within a row do not have side panels. This saves space and simplifies installation across multiple cabinets. Their structure ensures optimal cooling of the installed devices. TIP:You can have special control cabinets for complex requirements made individually with additional cut-outs, bores, ventilation or viewing windows. Terminal boxes are usually smaller than control cabinets. Depending on the place of use, they are used to accommodate cables or lines and are particularly space-saving. Outdoor control cabinets are specially designed for outdoor use and are particularly resistant to the effects of the weather. These are often used in industrial plants or on construction sites. Corrosive environmental conditions can prevail in the pharmaceutical and food industries. You should therefore choose particularly robust materials such as stainless steel for such locations. These are especially suitable for use under difficult conditions.What is the function of a control cabinet?A control cabinet protects the electrical and electronic equipment inside. Dust and water should be kept away. In addition, sufficient cooling of the installation should be ensured to prevent overheating. The control cabinet itself must also be designed in such a way that it protects against external influences such as vandalism. A control cabinet usually has a modular structure. An individual subdivision into power ranges and control ranges is ensured by mounting rails and mounting plates. In addition to a flexible structure, these also enable simple maintenance and repairs. The components must be arranged within the control cabinet in such a way that no electromagnetic or mechanical influences occur.Image: Schneider Electric NSYS3D6425 control cabinetA control cabinet shields the installation from electromagnetic emissions from its environment. Control cabinets are usually closed so that nobody can accidentally come into contact with the installations. In addition, a control cabinet is used for fire protection inside and outside. Controlling the current flow is also an important task of a control cabinet. It may be necessary to regulate or switch off the flow of electricity in certain areas of the network, for example when a device needs to be repaired or replaced. This ensures that just the right amount of current is flowing and that there is no danger to equipment or people.Is the temperature in my control cabinet correct?The temperature in the control cabinet is an important factor for the function of the components installed in it. However, it is not only the temperature itself that is important, but its constancy. Extreme fluctuations damage the electronic components. In general, one speaks of an optimal average temperature of 25°C. If there are larger fluctuations, condensate can form. This may impair the function of the installed devices. Thus, the average temperature is not a reliable guide. You should make sure that the temperature remains as constant as possible. If this is slightly higher than the room temperature, this usually does not damage the installation. On the contrary: the evaporation of moisture is promoted. Most of the components in the control cabinet are designed for an operating temperature of up to 50°C. In order not to impair the service life, a temperature of more than 35°C should not be exceeded permanently.What should you consider when choosing a control cabinet?Choosing the right control cabinet depends on numerous factors. Control cabinets are available in a variety of sizes, designs and price ranges and can be used for different purposes. Ask yourself the following questions:In which environment will the control cabinet be installed? This affects the material and the IP protection class.Is it a private system or a complex installation? The size of the closet depends on that.What meters and devices will be installed and how many?Will the cabinet be installed in a public or semi-public area? Then it should be lockable.Who should be granted access to the control cabinet?Is an alarm system necessary?Should the operating conditions be monitored (temperature, humidity)?Is air conditioning necessary?Is a smoke detector or extinguishing system necessary?and much more NoticeControl cabinets are not indestructible and can be damaged by vandalism, improper handling or extremely high temperatures. Therefore, when buying, you should pay attention to its suitability for the intended purpose.The control cabinets from the eibabo® shop are robust and durable. In this catalog you will find numerous variants of the best quality.

In addition to the switch cabinet itself, there may be other switch boxes or sub-distributors, depending on the complexity of the system. Empty and unequipped, the housings are made of metal or plastic. Depending on their size and equipment, these have bases for accommodating terminal strips or devices for mounting rail systems. In any case, you buy cheaply from eibabo® and receive your delivery in the shortest possible time.  Catalogue content:In this eibabo® catalogue Cabinet enclosures > Enclosure/switchgear cabinet (empty) you will find items from the following product groups:Item overview:Add-on cabinetAdd-on distributorBusbar systemCloset systemClosetsControl boxCorner cabinetCounter fieldElectrical enclosureElectronics housingEmpty plastic caseFood safeHousing solutionsHousing systemsHygienic housingIndoor housingIndustrial housingLarge closetLow-voltage distributorMetal frameworkOutdoor cabinetOutdoor heatingPlasticPlastic cabinetPlastic casePolycarbonateSingle cabinetSmall casefrom the following manufacturers:Manufacturer overview catalogue Switch cabinet empty:ABNAssmannBoplaDeviEatonEldonEnocHagerHeitecnVent ThermalPhoenixRittalSchneider ElectricSiemensSpelsbergTelevesTriaxVertivWeidmüller
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.

Combined arresters - eletric - Are you looking for combination devices to divert lightning currents and surge voltages for your electrical installation? But you are still not sure what requirements such a device has to meet? Learn more here. In order to be able to decide on a specific device, you must be aware of the dangers caused by lightning currents or surge voltages. Admittedly, these events are rare and often only last a few milliseconds. Nevertheless, major damage can result. We therefore always recommend appropriate protective measures to prevent damage to buildings and sensitive electronic devices. We support you in choosing the right item.Image: Dehn DSH-TNS-255 combined arresterWhat are combined arresters in power engineering?Combined arresters are of enormous importance for safety in electrical engineering. These limit lightning currents and overvoltages in electrical lines and divert them. Combined arresters are therefore used to protect sensitive devices such as computers, televisions or hi-fi systems.But what requirements do these devices combine?To understand this, we need to take a closer look at the overvoltage phenomenon. In Germany and large parts of Europe, the mains voltage is 230V. Overvoltages go well beyond this value. These are caused by switching operations by the network operator, lightning strikes, short circuits or electrostatic discharges. The resulting consequences depend on the level of the overvoltage, the duration and the speed of the voltage pulse. If suitable protective measures are missing, fires can break out or people can be injured. Since the type and extent of a fault caused by overvoltage and lightning current cannot be predicted, protective devices are constructed in three stages. We distinguish between coarse protection (type 1), medium protection (type 2) and fine protection (type 3). With each level, the overvoltage is further reduced until it can no longer pose a threat to the end devices. Combined devices for dissipating lightning current and surge voltage usually meet the requirement classes type 1 and type 2. In the following text we will explain in more detail what this means.Surge arresters and combination arresters are also referred to as Surge Protective Devices (SPD). They are usually installed in the installation distribution board or in the sub-distribution boards between the active conductors and earth. The devices are usually designed as pluggable modular devices or as devices for mounting on DIN rails. Other properties, some of which are optional, are:connectable lightning current and surge arrestershigh discharge capacity for lightning current surges up to 100 kA (10/350?s)optical status display / defect displayremote signallingshockproof and tolerable to vibrationsConnections can be labeled The construction of a lightning protection system with overvoltage protectionIn order to be able to decide on a specific combination arrester, you should know the entire structure of a lightning protection system with overvoltage protection.side noteBuildings are classified in lightning protection classes I to IV. This assesses 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.Whether a combination device is suitable for a building with a specific lightning protection class can usually be found in the product description. 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 The external lightning protectionAs the name suggests, external lightning protection is protective measures outside the building. These are lightning arresters, lightning conductors, earthing, fixings and so on. The external lightning protection diverts direct lightning strikes and the associated high lightning current into the ground before they reach the building. In Germany there is no obligation to install external lightning protection systems. Exceptions are buildings which:are over 20 meters highstanding free on a hilltophave a combustible roof (e.g. thatch or thatch)are open to the public (cinema, museum) However, external lightning protection always makes sense, even if your building does not meet any of these criteria. A lightning strike can cause serious damage. Information and high-quality items for setting up reliable external lightning protection can also be found here in the shop. Use our intelligent search.The internal lightning protectionEffective internal lightning protection and overvoltage protection protects apartments, buildings, industrial plants and the devices in them. The internal lightning protection is designed as equipotential bonding. For this purpose, all metallic pipe installations and cable installations in a house are connected to each other and to the main earthing bar. This can prevent voltage differences, lightning flashovers in the building and the resulting danger to people and technology.The overvoltage protectionInternal lightning protection includes overvoltage protection. This is where the combined arresters offered in this catalog come into play. In order to be able to select a suitable device, please consider the type of possible interference as well as the type of devices to be protected. As already mentioned, the overvoltage protection has a three-stage structure. Accordingly, three requirement classes for overvoltage protection devices are also available. We distinguish between type 1 (rough protection), type 2 (medium protection) or type 3 (fine protection). Type 3 standard devices provide fine protection and protect against voltages up to a certain level. Enhanced Type 2 devices provide additional protection against transient voltage spikes. The high protection standard of type 1 also protects against impulse currents. But what exactly does that mean for the combination arresters offered here, which in many cases meet the requirements of types 1 and 2? NoticeSurge protection has been a mandatory part of an electrical system in Germany since December 2018 and must be installed in new buildings. Type 1 surge protective devices are also known as lightning arresters. These divert high lightning currents via the internal or external lightning protection of a building. The residual voltage is reduced to a level between 6000 volts and 1300 volts. However, this basic protection is not yet sufficient to protect the end devices.Type 2 surge protective devices provide medium protection. The residual lightning voltage, which is already reduced by the type 1 devices, is further reduced in this stage to values between 2000 volts and 600 volts. Type 2 devices also limit dangerous transient overvoltages. These are caused by the switching of motors, transformers, circuit breakers or inductive loads. Disturbances of this kind are short-lived. However, these occur more frequently and cause the tension to rise suddenly.Type 3 protective devices further reduce the remaining overvoltage. This fine protection is installed as close as possible to the end devices to be protected.What should you pay attention to when buying a combi arrester?You are now familiar with the structure of a lightning protection system with overvoltage protection. With the installation of combination devices, you usually cover the requirements of test classes type 1 and type 2 with just one device. When buying, pay attention to high-quality components from trusted and well-known manufacturers. We also recommend retrofitting surge protection in older buildings, because the number of devices with sensitive electronics in our households is constantly increasing. When buying, also pay attention to:mounting typeRated voltage AC/DCHighest continuous voltage for AC and DCDissipation capacity for lightning current surgesnumber of polesSuitability for buildings with a special lightning protection classProtection level (must not exceed the impulse withstand voltage of the installation and the connected equipment) Considering your electrical installation in connection with the assessment of your individual protection requirements will help you to choose the right combination arrester. TIP:With a combination device, you save money and space in the control cabinet. You get easy-to-install, comprehensive protection. At eibabo® you can get a large selection of combination arresters for electrical engineering in different designs.

These connections are usually implemented using Wago terminals, luster terminals or terminal strips. However, these terminals cannot remain unprotected and freely accessible. There are terminal boxes in various designs and sizes for this purpose. With some, the clamping rails are already pre-installed and you only have to assemble the cables and lines. You can use these indoors, for example, as sub-distributors to supply your garage with electricity. Others are empty and can therefore be used freely for your individual cable connections. Specially sealed polycarbonate housings with protection class IP68 are available for outdoor use. You can use it to create installations in the garden or on the terrace. In the eibabo online shop you can buy terminal boxes cheaply and conveniently.
