In process industries, a contactor is a vessel where two streams interact, for example, air and liquid. See Gas-liquid contactor. For other uses, see Contactor (disambiguation). AC contactor for pump application. A contactor is an electrically controlled switch used for switching an electrical power circuit. [1]
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,
Jul 26, 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.
Mar 17, 2021 · A contactor is a component used to switch an electrical circuit on or off. It is considered to be part of the relay family, but the main difference is that they are used for applications or in circuits that require more current.
Mar 11, 2024 · 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.
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.
Jun 12, 2022 · A contactor is an electromagnetic switch that is used to turn on and off an electrical circuit. It’s also a device that can be controlled from a distance. It should be able to make, carry, and break currents in normal and operational overload circumstances. It’s closest to the load centre.
Oct 1, 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.
May 13, 2022 · Relays and contactors are widely used in industrial automation applications. Both these terms for components are used interchangeably by many engineers. Both the devices act like switches and both of them use the principles of electromagnetic induction to function.
