Circuit breakers are an essential part of any electrical system. But what’s the difference between an MCB, an RCD and an RCBO circuit breaker? An MCB (miniature circuit breaker) detects overcurrents, an RCD (residual current device) detects imbalances between the live and neutral currents, and a RCBO (residual-current circuit breaker with overcurrent protection) does both jobs in one go. The right product for you will depend entirely on what you’re working on.
