Contactor - Wikipedia
A contactor is an electrically controlled switch used for switching an electrical power circuit. [1] A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
What is Electrical Contactor? Types of Magnetic Contactors
A contactor is an electrically controlled switch used for switching a 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 are oftenly used for 150 Hp motor.
What is Contactor? Construction, Working, Operation
Definition: Contactors are nothing but electrically operated switching devices that work based on Faraday’s electromagnetic induction principle. The primary operation of that is much like a relay, but they are manufactured to carry high current typically up to 12500A.
What is a Contactor? Their Operation, Application & Selection
A contactor is a switching device, widely used for the switching of motors, capacitors (for power factor correction), and lights. As the name indicates it is used to make or break contacts like an ordinary on-off switch.
