Hager 63A 30mA RCD / RCCB

Hager earth leakage trip, trips with 30mA fault, switch rated at 63A.

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 over current (overload) or short-circuit conditions.
