Differential switch type A 4P 40A 300ma


Differential switches are devices that are placed in front of them and protect against leakage currents to earth unacceptable. They protect people against electric shock.

In case of a leakage current with a residual pulsating direct current, an imbalance appears in the primary coil of the toroid, thereby generating a residual magnetic field in the core. This residual magnetic field in turn generates a voltage and a current in the secondary coil which solicits over. The relay in turn solicits the release device and open the contacts under spring pressure.

Switching characteristics

  • According to EN 61008
  • Rated current on / off switching Im = 500A
  • Rated residual current on / off switching I?m?500A for 16 to 40A; I?m = 800A to 100A at 63
  • Protection against short-circuit protected by fuse = 10000A Inc at 230 / 400V 80A fuse gG
