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 come in many forms with varying capacities and features.
Contactors and relays are operated by applying a voltage to the coil of an Electro-magnet, which will cause a switch, (or several switches) to close. The circuit that applies the voltage to the coil is referred to as the control circuit, because it controls the main device that the contactor or relay is switching.
