Functions and applications Lightning Surge Protector V 25-B C according to VDE 0185, Part 1 and Part requirements + 100, and the design of a lightning protection equipotential connector. The unit is in line with DIN VDE 0675, Part 6 (Draft 11.89) A1, A2 rating of B + C grade protection requirements. Lightning protection installation in the building project, which guarantees equal potential power line connection. When an overhead power line into the building, part of the overhead line may introduce a direct lightning strike lightning current, on the introduction of such a building overhead power lines, the protective device may be used. V 25-B + C / 3 + NPE (B + C grade) can be used in TN-CS, TN-S, TT and IT systems in particular surge protector. The protection is based on DIN VDE 0100, Part latest needs 534 / A1 design comes in pairs protector allows simple, secure installation. High-performance surge protection OBO V 25-B + C has a special varistor circuit device containing good nonlinear characteristic (а> 30) zinc oxide varistor. High-energy surge even if the circuit appears, the device also can get the maximum degree of protection. Even when the surge current reaches 60 kA, protection voltage is still below 1.5 kV. Thus, the protective part can withstand a direct strike lightning current. In the case of overload protector built-in thermal protection circuit breaker can be detached from the main circuit module out to ensure the normal operation of the power supply system, at the same time status display window changes from green to red. OBO surge protector V 25-B + C is not only able to withstand high flow capacity of lightning current, but also has characteristics of a low-voltage protection, can be used as a B + C joint protection use. At a glance V 25-B + C with the use of the advantages of flag terminal, easy installation can cope with the impact of frequent surge current B + C joint protection, used in building the overall space smaller occasions install only the total distribution cabinet a protector protector pluggable components can damage the module hot plug replace protector connected to the base inside the base and the number of modules 1-4 easy installation of thermal windows indicating devices for circuit breakers and protectors wide scope of protection status at a glance with NPE spark gap module (applies to TN, TT and IT networks), the structure is more secure V 25-B + C / NPE has a reverse insertion protection to ensure the protection module simple, professional installation OBO V 25-B + C can be easily installed in any distribution box or switch box 35 mm rail. NPE protection module C 25-B + clever design C / NPE and between the base, so that modules can not be reversed insertion. This ensures correct installation protection module.
