Rccb Internal Circuit Diagram. Rccb means residual current circuit breaker. It is a current sensing device which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
Then rccb trip the circuit. Earth leakage circuit breaker or elcb. Typical circuits fed direct are lighting freezer storage heating.
This video about the rccb working principle rccb wiring connection and residual current circuit breaker installation diagram explanation rcd wiring dia.
Rccb residual current circuit breaker falls under the category of wide range of circuit breakers as we know there are several types of miniature circuit breakers like mccb which works on different operational principle and has different safety purposes. Rccb means residual current circuit breaker. Earth leakage circuit breaker or elcb. If any current leaks from any electrical installation there must be any insulation failure in the electrical circuit it must be properly detected and prevented otherwise there may be a high chance of electrical shock if anyone touches the installation an earth leakage circuit breaker does it efficiently.
