circuit breaker can make,break and carry current under
normal,short circuit and overloaded condition..It operates
automatically.
contactor can make,break and carry current under normal and
overloded conditions only but not in short circuit
condition.It can operates more no of times without
maintenance.
Isolator can break currnt only through that part of circuit
which is bot carrying any current.It is manually operated..
