Lighting/Surge Arresters Combi Controller

Cape Electric Corporation offers lighting/surge arresters ? Combi controllers. Operation and fields of application: lightning and surge arrester V25-B+C ensures lightning protection potential equalisation in accordance with DIN EN/IEC 61643-11. The device is an arrester of requirement Class B+C. It ensures potential equalisation for the energy supply line in lightning protection installation for buildings. The arrester can also be used in buildings that are supplied with power via an overhead line, since direct or partial lightning currents may be expected there as well. Version V25-B+C/3+NPE (requirement Class B+C) is a special surge arrester for TN-C-S, TN-S, TT and IT systems. This device was developed for the requirements of DIN EN/IEC 60364, to allow simple, safe installation of the devices. High-performance arrester OBO V25-B+C has a special varistor circuit made up of powerful zinc oxide varistors with a highly non-linear characteristic (a>30). This design ensures maximum protection even with powerful surges. Even at a maximum load Imax of 50 kA the protection level is below 1.5 kV. This enables this type of device to withstand even partial lightning currents from direct lightning strikes. In the event of an overload, the built-in isolating device isolates the faulty arrester module from the network and indicates this with a red field. Because of the low residual voltage, OBO lightning arrester V25-B+C can also be used as a combined arrester B and C. Features at a glance V25-B+C: simple installation via the marked terminals; combined arresters B and C for compact application; plug-in upper part; pre-wired arrester blocks, 1-4-pole blocks; thermal isolating device with optical indication; arrester with NPE spark gap in one module; and C 25-B+C/NPE with protection against reversed insertion (coding).
