Contactors are nothing more than a coil and a set of contacts. The coil of the contactor can be 24, 115, or 230 V, and even higher depending on the application. The contactor arrangement can be single ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

In many electrical installations, general-purpose contactors are used to switch the supply voltage to a small dry-type transformer on and off. One common reason this is done is for area lighting ...

When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

The REC Series is twenty times more durable than equivalent mechanical contactors and succeeds in handling high frequency switching. The REC Series is comprised of a 3-pole non-reversing version with ...

The new series of Cutler-Hammer Definite Purpose Contactors (DPs) are now available in a sleek, new sealed design. They are designed to improve control of refrigeration, air conditioning, ventilation, ...
