3P+N/Residual Current Circuit Breaker(RCB)

The Residual Current Circuit Breaker Series, also known as residual current operated protective device (RCD), is an electrical safety device that integrates overload protection, short-circuit protection and residual current protection functions. It can quickly cut off the power supply when personal electric shock, equipment leakage or grounding fault occurs in the circuit, so as to avoid electric shock accidents and electrical fires. It is widely used in the terminal power distribution systems of industrial plants, commercial buildings, residential dwellings, municipal facilities and other places. The series is mainly divided into two categories: residual current circuit breakers with overcurrent protection (RCBO) that integrate overload, short-circuit and residual current protection functions and can directly replace micro circuit breaker (MCB); and residual current circuit breaker (RCCB) that only have residual current protection function and need to be used in conjunction with micr…
