RCCB is the abbreviation of Residual Current Circuit Breaker, and its Chinese name is "residual current circuit breaker". It is an electrical device used to protect personal safety and prevent fires. RCCB is mainly used to detect leakage current in the circuit. Once the leakage current is detected to exceed the set value, RCCB will quickly cut off the circuit to avoid electric shock accidents and fires.
