difference between isolater and circuit breaker?

Answer Posted / sagar kakade

Isolator is nothing but a switch which is used for just on
and off the circuit. Circuit breaker is also used for on
and off the circuit, but the major benifit of using circuit
breaker in place of isolator is to trip on major electrical
faults like, a) Earth fault, b) over load, c) Under
voltage / No voltage, d) Short circuit fault. and damage to
the human beings as well as the electrical machinaries like
transformers, HT/LT panels, HT/LT cables, can be prevented.
