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.
When a relay is used to switch a large amount of electrical power through its circuits, it is given a new name, a Contactor. These contactors are very commonly used in industries for control of electric motors. Thus it is clear that contactor is only a special type of relay. Since a contactor is required for a higher load, a relay is always cheaper than a contactor. â¢ A relay is normally used in appliances below 5KW, while a contactor is preferred when the appliance is heavier. â¢ A relay is used only in control circuit while a contactor can be used in both control and power circuits.
