Answer / pravesh
relay is the device acttached to any circuit which makes it
work automatically.it has less operating voltage but in
contactor it works on the principle of cantact making that
either single phase voltage or 110v ac supply , the plunger
makes the other three phase contact and thus operats on
some high operating voltage

Answer / gafoor
Most circuit breakers are thermal devices that when excess
current run through them they heat up and trip (open up).
They can also be used as a switch to open a circuit.A
contactor is a electric relay that is essentially a
solenoid and a pair of electrical contacts. The solenoid is
activated and it closes the contacts
