A mains filter is an electrical circuit that both limits electrical interference from electronic devices into the public power grid and improves the electromagnetic compatibility of electrical devices against interference from the power grid.

VPU SERIES: long-lasting, safe, and future-oriented
We help our customers.

VPU SERIES: long-lasting, safe, and future-oriented

Our VPU I, II, and III surge protection devices effectively reduce the interference coupling that occurs with transient overvoltages, so that it remains well below the limits specified in EN 60664-3 (DIN VDE 0110-3). The entire system is exposed to fewer malfunctions. The arresters are coordinated by technical means.

Your advantages

  • No decoupling between Types I, II, and III required
  • Tested according to IEC 61643-11 and DIN EN 61643-11
