Difference between MCB and MCCB RCCB Taking circuit breaking capacity a notch up — RCCB or Residual Current Circuit Breaker is a standard protective device, recognized as essential lifesaving equipment. It disconnects the circuit offering protection against electrical leakage or electric shock caused by...
MCB (Miniature Circuit Breaker)—rated current not more than 100 A. MCCB (Molded Case Circuit Breaker)—normal rated current is up to 2,500A with the thermal or thermal-magnetic operation. The characteristics of low-voltage circuit breakers are given by international standards such as IEC 947....
