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.
