VPU AC II 3+1 300/50
Weidmüller VPU I (type I), VPU II (type II) and VPU III (type III) surge suppressors effectively reduce coupling interference that can occur during transient overvoltages, even well below the insulation coordination limits prescribed in EN 60644-3 / DIN VDE 0110-3. As a result, the entire installation is thus less disturbed. Surge arresters are coordinated by technical means. Thus, the decoupling between types I, II and III is unnecessary. The surge arresters are tested according to IEC 61643-1 / DIN EN 61643-11 and can be installed on systems according to IEC 61643-12 / VDE V0675-6-12 and IEC 62305-4 / VDE 0185-4. This lightning and surge protection for use in power supply systems. Weidmüller offers different products depending on the type of electrical network and the voltage level. Special type I and type II protection is even available for photovoltaic applications.
