SFP 1-20/120AC - EMC filter surge protection device

Device protection, according to type 3/class III, with mains interference filter to prevent high-frequency interference voltages, for 1-phase power supply networks with separate N and PE (3-conductor system: L1, N, PE), with remote indication contact.

  • Optimized protective effect with combined protective circuit for absorbing transient overvoltages for attenuating high-frequency interference
  • Symmetrical design of the protective circuit with surge protection components on the input and output sides of the filter
  • Protection against excessive heating with thermal monitoring of the protective circuit
  • Versatile in use with universal circuit design
