Differential switch type A 2P 63A 300ma

Differential switch type A 2P 63A 300ma

function

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.

operation
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.
