In the most convenient way, a contactors is an electronic switch or contactor transmitter typically used for turning off and on an electrical circuit. This is the integrated component relay families; however, the distinguishing feature is a contactor being used in such applications where higher potential or capacity currents are involved. Contactors are commonly employed in lighting circuits, motors, heating, and many other electrical loads since a contactor would work automatically or as a control system for a device or motor starter component.
Enrgtech offers a few of the top brands of electrical contactors, such as Schneider Electric, Siemens, Eaton, ABB, and Allen Bradley. We also have a variety of add-ons that improve the performance of the contactor, such as mechanical interlocks, auxiliary contacts, and contactor overload relays.
What are Electrical Contactors?
Typically manufactured to be linked with a high voltage load component, interfaces integrations spring-loaded interfaces which create or break power supply distribution load. They are manufactured to start and close so fast to help in arc control, making sure the contactor's the potential to interfere with heavy load motor currents by using limited impair over an extended lifetime. The majority of devices are more often turned off and on, whereas a contactor is frequently installed. Moreover, some contactor configurations are manufactured for various current criteria. Since they range from fundamental light switches to complicated applications, including controlling electromagnets, interfaces are extremely full-fledged.
How Does the Contactor Function?
Contrary to normal relays, interfaces are made expressly to be connected to high-current load devices. A contactor is a switch that can be controlled remotely and is used in larger-scale control circuit applications because it is made to switch a significant quantity of electrical power across its contacts. A device is referred to as a contactor if it can switch more than 10 amperes. Additionally, these devices have high coil voltages, which are uncommon in relays.
Contactor Configurations
As per your application's needs, there are several types of contactors, and each type has its own set of requirements. Some essential requirements are:
- AC Interface or DC Interface with coils including 12 V, 24 V, 48 V, 110 V, 240 V, 400 V, and 440 V.
- Switching or non-reversing operation.
- AC3 and AC1 classifications
- Contactors with two poles, three poles, four poles, and even eight and 10-pole variants.
- Numerous contact structures.
- IEC principles
