P/N & Price

The Residual Current Circuit Breaker(RCCB) with Overload Protection 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 between the live and neutral wires.
