Residual Current Circuit Breakers

P/N & Price

A Residual Current Circuit Breaker is essentially a current sensing device. It will trip off whenever a fault occurs in the circuit. RCCB is designed such way that it continuously senses and compares for difference in current values (residual current value) between the live and neutral wires.
