 Functions and applications 

 Lightning surge protector V 25-B + C according to VDE 0185, Part 1 and Part 100 requirements, and the design of a lightning protection equipotential connector. The device is in line with DIN VDE 0675, Part 6 (Draft 11.89) A1, A2 rating of B + C-level protection requirements. Lightning protection installation in a building project, it guarantees that the power lines and other potential connections. When the power cord into the building overhead, the overhead line may introduce some direct lightning strike lightning current, in which the introduction of building the power lines overhead, the protector can also be applied. 

 V 25-B + C / 3 + NPE (B + C level) for TN-CS, TN-S, TT and IT systems in particular, the surge protector. The protection is based on DIN VDE 0100, Part 534/A1 from the latest design needs, allowing the pair protector simple, secure installation. 

 High Performance Surge Protector OBO V 25-B + C has a special pressure-sensitive resistor circuit, the device contains a good nonlinear characteristics (а> 30) of zinc oxide varistor. Even if the circuit is high-energy surge occurs, the device also can get the maximum degree of protection. Even when the surge current reaches 60 kA, the protector of the voltage is still less than 1.5 kV. Therefore, the protector can withstand lightning current cloud-to-part. In overload situations, the built-in thermal protection circuit protection module can be spun off from the main circuit, ensuring power supply system to work, at the same time status display window from green to red. 

 OBO surge protection V 25-B + C is not only able to withstand high flow capacity of the lightning current, but also has characteristics of low-voltage protection, can be used as a B + C joint protection uses. 

 Installation 

 OBO V 25-B + C can be easily installed on any distribution box or switch box of the 35 mm rail. NPE protection module C 25-B + C / NPE and the base between the clever design, the module can not be reverse-inserted. This ensures the protection of the right module
