More about residual current circuit breakers
Residual current circuit breakers (RCCBs) are protective devices that detect leakage current flowing to earth and automatically disconnect the circuit. Unlike GFCI circuit breakers designed primarily for personnel protection, RCCBs are available in sensitivity ratings from 10mA to 300mA or higher. These circuit breakers provide ground fault protection only — for combined protection, residual current circuit breakers with overcurrent protection (RCBOs) integrate both functions.
