Residual Current Circuit Breaker Rccb

RCCB (Residual Current Circuit Breaker) or RCD (Residual-current device) are aimed to protect people from the risk of electrocution and fire that are generally caused due to the faulty wiring. An RCCB is also very useful when a sudden earth fault occurs in the circuit.

RCCB is basically an electric wiring that trips or disconnects when imbalance or mismatch in electric current is detected. The best part about RCCB is that it does not take much time to take the control over the imbalanced electric current; RCCB takes only about 20 milliseconds to trip. RCCB is essentially a current sensing equipment that is used to control the low voltage circuit from the fault. It comprises a switch device which is used to turn off the circuit when there is a fault.
