4. WORKING PRINCIPLE
RCCB (Residual Current Circuit Breaker)
There are two types of electrical faults which are very dangerous. One is when there is a high current fault due to some short circuit current, which can be protected by an MCB. Second is when earth leakage arises due to wet hands touched by someone. And an MCB cannot detect this fault, whereas it can be detected by the RCCB. The main principle behind the function of the RCCB is when current is flowing through the appliances it may return in full. There is the difference of milliampere and it may detect and trip the power supply in the circuit. When the current flows out from the appliances, then it is known as residual current. The RCCB is designed in such a way so that the difference can be compared between residual current values between the live and the neutral wires. If there is a small change between the current value of an account, it will trigger the RCCB to trip the circuit. Now it can be said that RCCBs sense the difference between the current value in phase and neutral and can break the circuit.
In the RCCB circuit breaker, the ON and OFF buttons are clearly visible with the help of a window provided at the top of the housing. With the use of advanced technology, some of the manufacturers have come out with the entire protection for the short circuit as well as for the earth fault, this device is also known as the RCBO. In such a situation, the MCB is not required.
