Answer Posted / dipak patil
the main difference beetween Isolator and CB is that,
isolator has no Making or braking capacity, that is that it
cann't break or make the circuit that carrying load current
unlike circuit breaker. CB can make as well as break the
circuit under normal load condition or under fault
condition.Under fault condition protection operates CB.
Both Isolator and CB can be operated manualy or
automaticaly as per application.
