Earth Leakage Circuit Breakers (ELCB) and Residual Current Circuit Breakers (RCCB) protect against potential electric shocks caused by leakage currents. ELCBs detect leakage currents that may flow ...

An MCB (miniature circuit breaker) can be reset and uses an electromagnet to open a switch if the current goes above a certain value. MCBs switch off the current faster than a fuse. An RCCB ...
