Residual Current Circuit Breaker Diagram. Purpose of rccb. Rccb means residual current circuit breaker.
The proper rccb connection diagram with mcb is given below. Then rccb trip the circuit. It contains a switch device that switches off whenever a fault occurs in the connected circuit.
A residual current circuit breaker rccb is a key safety measure when it comes to the protection of electrical circuits.
It contains a switch device that switches off whenever a fault occurs in the connected circuit. Residual current circuit breaker. Residual current circuit breaker is essentially a device which senses current and disconnects any low voltage unbalanced current. As rccb cannot give protection from short circuit and overload faults so generally rccb is always used with mcb.
