Legrand XC3 4X 63A 30Ma Residual Current Switch 403192

Legrand XC3 4X 63A 30Ma Residual Current Switch 403192 These devices provide protection against dangerous shock currents in case of direct or indirect contact with live conductive objects. Wiring faults, insulation problems, defective appliances, or faults in electrical systems can trigger dangerous leakage currents, leading to accidents or electrical fires. Residual current devices can prevent this. Residual current protection relays cut off the energy in the circuit they are connected to quickly and safely if the threshold differential current is exceeded. Residual current relay provides protection against undesired situations in the electrical installation with its 30mA life protection and 300mA fire protection feature due to its working principle.
