A contactor is an electrically controlled switch used for switching an electrical power circuit, similar to a relay except with higher current ratings. A contactor is controlled by a circuit which has a much lower power level than the switched circuit.Contactors come in many forms with varying capacities and features.Unlike a circuit breaker, a contactor is not intended to interrupt a short circuit current. Contactors range from those having a breaking current of several amperes to thousands of amperes and 24 V DC to many kilovolts. contactor is controlled by a circuit which has a much lower power level than the switched circuit.

Contactors. A contactor is installed to provide the same function as a switch or circuit breaker, but has a completely different operating principle. When you move a switch or a circuit breaker into the closed position and then stop, the switch or circuit breaker will stay in that position.
