Overvoltage arrester Low voltage

Weidmüller's overvoltage protection in the VPU I (Type I), VPU II (Type II) and VPU III (Type III) series effectively reduces interference coupling caused by transient overvoltages, even well below the limits specified by insulation coordination according to EN 60664-3 / DIN VDE 0110-3. As a result, the entire system is exposed to less interference. The coordination of the arresters is achieved by technical means. This means that no decoupling is required between types I, II and III. The arresters are tested according to product standard IEC61643-11 / DIN EN 61643-11 and can be installed in systems according to IEC 61643-12 / VDE 0675-6-12 or IEC 62305-4 / VDE 0185-4. This lightning and surge protection is suitable for use in power supply systems. Weidmüller offers various products depending on the type of grid and voltage level. Also for photovoltaic applications there is a special protection type I and type II, overvoltage protection, with remote contact, TN-C-S, TN-S, UP (L / N-PE) ≤ 1.5 kV
