Socket - A socket is much more than an inconspicuous power supply on the wall. Find out here which sockets are available and why you can never have enough of them. In addition to buttons and switches, sockets are among the most important products of all manufacturers of switch programs. A socket is installed either permanently on a wall (surface-mounted socket) or recessed (flush-mounted socket). Sockets can also be part of a mobile line coupling, such as table or multiple sockets. There are also sockets on extensions that are intended for mobile use. A socket is mostly used for the power supply. There are also sockets for telephone / telecommunications and for the data transmission sockets. Devices are usually supplied with single-phase alternating current (in Europe 230 volts) or three-phase alternating current (three-phase current with 400 volts) via classic sockets. There are also standardized sockets for 12V direct current. There are separate socket systems for the supply of higher voltages and currents.Basic information about sockets - in a nutshellA distinction is made between the flush-mounting and surface-mounting types. With the flush-mounted variant, sockets are mounted in switch boxes, which in turn are embedded in the wall. In the 'surface-mounted' variant, sockets are attached to existing walls, usually with dowels and screws.Double sockets are usually nothing more than two single sockets. They obtain the energy from the same supply line. Flush-mounted variants can be optically connected to one another via the frames of the switch range. With surface-mounted devices, both sockets are supplied in one housing.A socket insert is a device for installation in the switch box. It is either attached using claws (clamp connection) or by screwing the base plate of the insert to the screw holes of the switch box. The insert must be supplemented by the frame of the switch range.High-quality moisture-proof sockets usually have a self-closing cover and a rubber seal around the base. They are used in bathrooms, kitchens or utility rooms.Outdoor sockets must protect the current-carrying cables from rain and snow. Their housings are often particularly stable in order to prevent damage from mechanical influences.The degree of protection is a determining variable for the place of use. The best known is the two-digit IP protection class (IP = International Protection / Ingress Protection). The first digit stands for protection against contact and foreign bodies, the second digit for protection against water. The higher both digits, the safer. Planning of sockets - there is no such thing as too muchIf I were to build a house again, I would do many things differently.' You hear it very often like this or something similar when you talk to builders. Not infrequently, the planning and implementation of the electrical installation is one of the things that could be better. It is often the insufficient number of sockets that makes everyday life unnecessarily cumbersome. For example, if there is no socket in a dark corner of the room, you must lay an extension cord for the lamp. You probably won't connect very many electronic devices in a bathroom. A living room is usually equipped with many devices and is occasionally rearranged. Many sockets offer flexibility here. TIP:Sockets are very cheap to buy compared to the whole building. Do not plan too tightly, but generously. But positioning also plays an important role. Plan ahead with the layout of your home, the furnishings, and the purpose of the room. Think about the different uses throughout the year. For example, the following are often overlooked:Sockets in the window reveal to supply the Christmas lightsSockets at ceiling height for extractor hoods, infrared heaters and the likeSockets in the attic (for later expansion)the right sockets in hobby rooms, if necessary for devices that require three-phase currentOutside sockets on the balcony or terraceOutdoor sockets near a cistern or water barrel to feed a pumpOutside sockets in the carport or near storage areas for wood and the likeOutside sockets on the property line / driveway The Schuko sockets in the eibabo® online shopThere are many types of sockets. The so-called Schuko socket is the standard in Europe. The abbreviation SchuKo stands for 'protective contact' and is a designation for the German-speaking area. Internationally, these devices are referred to as type F sockets. Cables with three cores are connected to sockets of this design, one of which serves as a protective contact. This derives leakage currents. The matching plugs (e.g. on electrical devices) are also constructed according to this principle. In this catalogue, we present you with high-quality sockets from over 30 manufacturers, including Gira, Jung, Merten, Hager, Berker, Legrand BTicino, Busch-Jaeger and Siemens.How much load can a single socket withstand?A classic 230 volt household circuit is usually protected with 16 ampere fuses. This results in a maximum load capacity of the circuit of 3680 watts (16 amps x 230 volts). This means that you could theoretically draw 3,600 watts of power from a standard household socket. NoticeWhen it comes to electrical installation, it is advisable never to push individual devices to their capacity limits. In practice, about 2500 watts should not be exceeded at a socket. Based on Central European standards, 200 watts to 300 watts per individual socket is assumed in everyday use. With double sockets it is up to 500 watts. You should take this guideline into account when planning the maximum number of outlets per circuit for your installation.Does eibabo® also offer sockets of other standards?eibabo® is an international online mail order company and offers sockets that are common outside of Europe. The best-known form is the NEMA standard, which is not used in Europe (with a few exceptions). NEMA stands for National Electrical Manufacturers Association and describes a whole range of different sockets and power plugs. These are commonplace in America, such as the United States, Mexico, and Canada. Type B (NEMA-5-15) single-phase AC power is most commonly used in the United States. The regular operating voltage is 120 V, the mains frequency is 60 Hz. NEMA-6 series connectors are intended for heavy loads such as electric ovens. The NEMA system is also in use in parts of Asia, including Japan and Thailand, China and the Philippines. In addition, at eibabo® you will find sockets according to British Standard, Swiss Standard or Australian Standard.How do I integrate a standard Schuko socket into the smart home?An existing socket can be easily expanded in terms of functionality using a WLAN socket. As a rule, these are adapter plugs that you plug into the existing socket. These represent a link between the end device and the socket. An associated application (software) enables the connection to the home network. But it doesn't have to be WiFi. Other models use Zigbee, Z-Wave and Bluetooth as radio technology. If your electrical installation is just being planned, we recommend reserving a few sockets for your smart home. Then you have the option of using the corresponding flush-mounted sockets. These look visually appealing like classic sockets. You no longer need an additional adapter plug.Already knew?At the beginning of the electricity age, sockets and light switches were considered status symbols. Those who were self-respecting presented the electrical installation of the house 'surface-mounted' and clearly visible to everyone.The advantages of such sockets are, on the one hand, that the devices connected to the sockets can be disconnected from the power supply quickly and easily via the smart home system. In this way, the devices do not run on standby and save electricity. On the other hand, you can operate the sockets when you are not at home. If such a device is compatible with Apple HomeKit, Google Assistant or Amazon's Alexa, you can use it to control it.What is the difference to a socket with increased contact protection?At first glance, a socket with increased contact protection can hardly be distinguished from a classic socket. Some manufacturers mark such a model with a small symbol on the case.Image: Gira 045327 Schuko socket outlet with child protectionSockets with increased contact protection have an additional internal safety device that can vary depending on the manufacturer. In some models, this consists of rotary vanes. These open when both pins of a connector exert pressure on them at the same time. With other systems, the central insert can be rotated. So no object can be inserted into the holes of the socket. The installation of such sockets is recommended, for example, where children may have access to them. In other wordsThe designation 'Schuko' for protective contact has nothing to do with protection against accidental contact. Protection against accidental contact must also be provided. An alternative to the socket with increased protection against accidental contact can be separate socket protection. These plug into a standard socket and often work with a twist or slide motion as well. It is very safe with socket locks or lockable flaps.Why should I lock an outlet?Sockets are everywhere. These cannot always be monitored. In times of constantly rising energy costs, one often hears about electricity being stolen unnoticed via a hidden socket. This is made particularly easy for thieves if the socket is publicly accessible. Even if animals, children or other vulnerable people are constantly in the immediate vicinity of the socket, we recommend a lock. Lockable sockets or socket locks are available in the eibabo® shop at reasonable prices. Use our intelligent search.Are there sockets for other areas of application?In addition to classic sockets for everyday use, there are sockets in special shapes. You may need sockets in a place where neither a flush-mounted socket nor a surface-mounted socket is possible. A classic example is the junction box. Here you need a socket with mounting options on the DIN rail. Such models are often adapted in width to the pitch units in the junction box. Another special form are the so-called CEE sockets. These are available in the strengths 16 A, 32 A, 63 A and 125 A and are equipped with three to seven pins. Different colors represent the appropriate nominal voltage. The eibabo® shop offers CEE sockets and sockets for the junction box in separate catalogues.  Catalogue content:In this eibabo® catalogue Domestic switching devices > Socket outlet you will find items from the following product groups:Item overview:Bike socketBrightness sensorConcealed insertsData socket insertFine protectionFlange socketGround pinHinged cover socketHospitalHousehold wall boxInstallation socketInstallation switchMachine socketOvervoltage protectionPin contactProtective contact wall boxRecording moduleRoom temperature controllerSchuko socketSchuko wall boxScrew fixingSocket connectorSocket coverSpare partSpecial deviceSurface-mounted housingTouch protectionWaterprooffrom the following manufacturers:Manufacturer overview catalogue Socket:ABLABNBachmannBEGA GantenbrinkBerkerBusch JaegerE+P ElektrikEatonElsnerElsoEltakoEVNGiraHagerHamaHeraHHGJungKleinhuisLegrand BticinoLegrand SEKOLützeMennekesMertenMurrelektronikOBOPehaPhoenixPollmannSchneider ElectricSiemensStahlStriebel & JohnTehalitWalther
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 include: CombiController, lightning current arresters, arresters for busbars, combined arresters for meter applications, type 1 + type 2 combined arresters. Also take a look at our extensive range of single-pole and multi-pole devices with integrated arrester back-up fuse.  Catalogue content:In this eibabo® catalogue Earthing, lightning and surge protection > Combined arrester for power supply systems you will find items from the following product groups:Item overview:Charging infrastructureCombiControllerCombined arresterCombiner boxComplete blockComplete unitElectromobilityEnergy distributorFuse holderGas arrestorInsulating distributorInsulating housingInverterLightning protectionLightning protection housingLightning protection moduleLightning rodLoading deviceOvervoltage protectionPhotovoltaicPhotovoltaic system solutionPhotovoltaic systemsRail conductorSurge protection deviceSurge Protection EnclosureSurgeControllerSystem solutionTerminal blockfrom the following manufacturers:Manufacturer overview catalogue Combined arresters - eletric:ABBDEHNEatonFinderHagerOBOPhoenixSchneider Electric
Hifi complete system - Do you still remember the huge hi-fi towers with turntables, receivers, double cassette decks and equally high loudspeakers that represented the center of home entertainment in many apartments up until the turn of the millennium? But those times are now over. Cassettes are no longer used, turntables are experiencing a renaissance among a few music enthusiasts, and streaming services and digital radio have significantly changed the way we consume music. Interfaces to other multimedia end devices represent the new challenges for complete hi-fi systems. In addition, the devices are becoming more and more compact without sacrificing acoustic performance. The latest generation of micro system systems, compact devices and hi-fi music centers in different price ranges and performance levels are available from the eibabo technology store.Catalogue content:In this eibabo® catalogue Consumer electronics > HiFi-set you will find items from the following product groups:Item overview:Audio systemAV home theater systemCompact systemDVD facilityDVD home theater systemHifiHiFi micro systemHiFi MicrosystemHiFi midi systemHiFi MidisystemHiFi mini systemHiFi MinisystemHiFi systemHiFi-setHome cinema systemHome theater systemInvestmentMicro complete systemMicro systemMicro system plantMidi systemMini hi-fi systemMini systemMusic CenterStereoStereo systemSystem plantWireless hi-fi systemfrom the following manufacturers:Manufacturer overview catalogue Hifi complete system:Beko Grundig CEGrundigGrundig Intermed(CE)LencoLG CE ElectronicsPanasonicPanasonic Deutsch.CESonyTechniSatTelestarWörleinW?rlein
