An RCCB detects leakage current by comparing the current flowing into and out of a circuit. When an imbalance is detected, it disconnects the supply to support protection against electric shock and insulation faults.
Browse ABB and Schneider Electric 2-pole and 4-pole RCCBs in common current ratings from 25 A to 63 A, with 30 mA and 300 mA sensitivity options. An RCCB does not provide overload or short-circuit protection by itself and is normally coordinated with a suitable miniature circuit breaker. If combined protection is required in one device, see the RCBO collection. Final selection should be confirmed by a qualified electrician.
