Answer Posted / shahid khan
relay senses the abnormal condition and whenever it exists ,
relay contacts get closed which in turn closes the trip
circuit of circuit breaker.
The term "Contactor" is often used for electromechanical
witches that control large motor loads.
both are used for switching but contactor for high currents
and relay used upto 5 or 6 amp. current
