RCCB (Residual Current Circuit Breaker) is an electrical device used to protect personal safety and prevent fires. Mainly used to detect leakage current in circuits. Once the leakage current exceeds the set value, RCCB will quickly cut off the circuit to avoid electric shock accidents and fires. RCCB is widely used in household, commercial and industrial fields and is a very important electrical protection device.
