A contactor is an electrically controlled switch used for switching an electrical power circuit. 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.
Learn what an electrical contactor is, how it works, and what types of contactors are available. A contactor is an electromechanical device that switches a power circuit, similar to a relay but with higher current ratings.
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.
Oct 1, 2019 · Learn what a contactor is, how it works, and what types of contactors are available. Compare and contrast contactors with relays, and find out how to shop for contactors.
Mar 17, 2021 · Learn about contactors, electrical components that switch circuits on and off, and their main components, types and applications. Find out the difference between contactors and relays, and the history and inventor of contactors.
A contactor is a large relay, usually used to switch current to an electric motor or another high-power load. Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts .
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.
