Siemens 5SV5644-6 Leakage Current Three Phase 40A/300MA
Siemens 5SV5644-6 Leakage Current Three-Phase 40A/300MA These devices provide protection against dangerous surge 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.
