Residual Current Circuit Breaker Diagram. It contains a switch device that switches off whenever a fault occurs in the connected circuit. It is a leakage current sensing device which can automatically measure and disconnect the circuit whenever a fault occurs in the associated circuit or the current exceeds the rated sensitivity.
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. 23 01 2011 by lemau 7 comments. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
The circuit equation isn t quite right given the indicated current directions on the diagram.

I1 and i2 are the same positive in phase value so the first equation should then be di i1 i2 0 note that in this case it is a minus not plus. 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.
