Brand: Germany OBO Product Details Price: Minimum purchase quantity: Any Brand / Model: / lightning protection zones: 1-2 Products OBO power mine V20-C / 3 + NPE- lightning arrester Details Brand / Model: / lightning protection zones: 1-2 Maximum discharge current: 40K Response time: less than 25n temperature range: -40-80 nominal discharge current: 20K Scope: branching distribution cabinet OBO lightning protection in buildings is V20-C / 3 + NPE- lightning protection functions and applications in accordance with the requirements of DIN VDE 0675, Part 6 (Draft 11.89) A1, A2, the surge protector V 20-C is part of C-level surge protection device. It protects electrical equipment from a variety of voltage surges. It is available from a single module to 4 modules of different types. Type V 20-C / 3 + NPE (C grade) for TN-CS, TN-S, TT and IT systems in particular surge protector. The protector is designed according to DIN VDE 0100, Part new demands 534 / A1, and to achieve a simple, secure installation. V 20-C contains a high non-linear characteristic (α> 30) of zinc oxide varistors. The device has a short response time, low-level protection, the advantages of high-pass flow and long life, especially when the lightning surge protection device by subsequent current does not appear. If the surge protector is damaged due to overload, the built-in circuit breaker means timely action, disconnect the power source, while fault indication window display color changes from green to red. Installation V 20-C can be easily installed in any distribution box or switch box 35 mm rail. Multi-module protector modules are connected by an internal grounding jumper in the factory, so protection is only needed once the ground (PE) connection. 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.
