Residual Current Circuit Breaker (RCCB)
NB1LG-40 Residual Current Operated Circuit Breaker
Final electrical appliances, residual current operated circuit breakers are mainly applicable to AC 50Hz, rated voltage single-pole two-wire, two-pole 230V, rated current up to 40A circuits. When a person is electrocuted or the grid leakage current or voltage exceeds the specified value, the residual current operated circuit breaker can act within an extremely short time.
