Answer Posted / snowwhite10
isolator is a knife switch and it is used to open a circuit
under no load.such switches are used in the both sides of
the circuit breakers so that repair and replacement of the
circuit breakers could be done.they are never opened when
current is flowing in the line.....
circuit breaker is an equipmnet which can make or break
contacts under load ,no load or fault conditionsrelay is
always used with circuit breaker ..relay detects the fault
and circuit breakers does the function of current interruption..
