80 Amp x 100 mA Trip Switch

Earth leakage trip, trips with 100mA fault, switch rated at 80 Amps.

Mounts onto DIN rail.

An RCCB (residual current circuit breaker), sometimes called RCD (residual-current device), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCCBs are designed to disconnect quickly enough to prevent injury caused by such shocks. They are not intended to provide protection against overcurrent (overload) or short-circuit conditions.
