Abstract

In a residual current circuit breaker having a tripping solenoid (11) for opening switch contacts (RC1, RC2) to interrupt current flow to a load (10) in response to a load current imbalance being detected (4,3) a Triac (54) is included to interrupt the current flow more rapidly than the time taken to open the switch contacts, whereby enhanced safety is achieved.
