Q. Function of circuit - breaker, difference between circuit breaker and 'isolator'?

Ans: The function of circuit breaker is to break the electrical continuity in the event of faults duly isolating the faulty part. Isolator is switching device, which operates in OFF load only. Circuit Breaker is switching device, which can operate in, OFF or ON load.
