What differance between Circuit brekar and Isolater?
Answer Posted / habib
Circuit breaker is device whcih disconnect the equipment
during fault condition automatically,but isolator does not
disconect the equipment automatically during fault
condition.
Isolator should be operate after deenergizing the
line,because isolator is not having any special arc
quenching facility like sf6 or vaccum in it.cb is having
this facility.
Note:- Isolator is a OFf load device it should follow the
CB operation
