Answer Posted / sachin
A circuit breaker is designed to break a circuit which is
carrying current at the time. Where large currents and/or
voltages are present, the opening of the circuit may induce
dangerous arcing, so means such as air blast must be used
to "blow out" the arc.
An isolator is only designed to isolate a circuit or other
component after the current has already ceased, so it
doesn't need to have any means to stop the arc.
Thus in high voltage/high current installations such as in
power stations or grid switching stations, the initial
operation to isolate the circuit, whether planned or as a
result of a fault, is by the circuit breaker, the isolator
is then used to isolate the circuit breaker for maintenance
or repair.
