AC contactor for pump application. 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.
A contactor is an essential part that is used to control the various equipment's electrical/electronic circuits. for example, starting of an induction motor,

26 Jul 2021 · Learn what a contactor is, how it works, how to wire a contactor, and the difference between a contactor and a relay.
Magnetic Contactor. The design of this type of contactor is most advanced among all other types of contactors. This is an electromagnetic type contactor and it can operate automatically. It requires a small amount of control circuit to turn on and off the load. Therefore, the operation of this contactor is safe compared to manual contactor.
30 Jan 2023 · A contactor is a specific type of relay, although there are some important differences between a relay and a contactor. Contactors are principally designed for use in applications where a large amount of current needs to be switched.
5 Apr 2023 · The solution to this problem is an electromagnetic contactor, a special class of relay intended for motor control. In addition to more rugged construction and larger, more robust contacts than relays, they employ arc suppression techniques that include special materials and faster contact closing and opening.
A contactor consists of an electromagnet, a set of power contacts, and a spring enclosed inside an enclosure. Some of them have built-in economizers, that can reduce power consumption in their coils. Certain arrangements for arc extinction are also made inside for making and breaking the operation.
1 Okt 2019 · Basically, a contactor is an electrical switching device. It is used for switching an electrical circuit on and off. It is a special type of relay, but there is a basic difference between the contactor and a relay.
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 .
