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.
