Surge protection devices of class 1

Overvoltage protection in single and three-phase voltage circuits [230 / 400V] 50 Hz.

The most important characteristic of Class 1 arresters is their ability to drain Iimp lightning current (pulse form 10/350 ms).

The devices in this series are intended for installation in zones 0A-1 in accordance with the concept of protection zones (IEC 61312).

  • voltage protection level Up≤4,0 and 2.5 kV;
  • patented sealed gas discharger and arc control pot;
  • no blow hole - it is not required to keep the permissible distance to other devices;
  • lightning current limit up to 100 kA (10/350 ms);
  • V-shaped connection is possible;
  • no leakage currents - possible installation before the counter;
  • optional remote signaling contact (FM version);
