Contactors

A contactor is a relay designed to switch a large amount of electrical power through its contacts, and is commonly used in the control of electric motors and lighting systems. A contactor can function on its own as a power control device, or as part of a starter.
Designed to be connected to high-current load devices, contactors incorporate spring loaded contacts that make or break power supply lines to a load. These contacts are designed to open and close very rapidly to assist with arc suppression, ensuring the contactors ability to interrupt heavy motor currents with minimal damage over a longer life cycle.
In any device that is frequently turned off and on, a contactor is often employed, and different contactor configurations are designed for different current requirements. From uses in basic light switches to complex applications such as controlling electromagnets, contactors are highly versatile.
The RS Range of contactors are available in a variety of pole and throw combinations, to suit your application.
