An RCCB (Residual Current Circuit Breaker) is a safety device designed to protect people from electrical hazards. It immediately disconnects the power supply when a residual current (leakage current) exceeding the permitted limit is detected, typically caused by leakage through a person or to the ground. Applicable Standards for RCCB IEC 61008-1 specifies the general […]
