40A 30Ma Ac 2P Tracon Differential Circuit Breaker

Residual Current Device 40A 30mA AC 2P

A residual current device is a protective device used in electrical installations that protects against electric shock by detecting insulation leaks in electrical circuits. It works by comparing the electric current in two wires – the live and neutral – running through the circuit. Under normal conditions, the current in both wires should be equal. In the event of an insulation leak, i.e., a current leak to earth, the current in the wires becomes unequal, which causes the residual current device to trip and interrupt the circuit. A differential circuit breaker is used in various electrical systems, particularly those with a high risk of electric shock, such as installations in wet rooms, near machinery, in industrial plants, and in rooms where people work directly with electrical equipment. It is a mandatory device in electrical installations in residential and public buildings, as required by building regulations. It is also used in industrial and agricultural installations.
