WebMay 30, 2004 · An RCD (Residual Current Device) is a generic term for several types of devices which protect a circuit against hazards from earth leakage faults. RCD's monitor imbalance in phase and neutral and "trip" when such an event occurs. An MCB (miniature circuit breaker) is a device which protects circuits from overcurrent and short circuits … WebThe earth fault relay is a type of relay that can sense the faults between the phase and earth. The major function of an earth fault relay is to operate for the leakage currents to the earth. This relay can detect the earth’s fault, so we can say that RCCB does the same function.
