    AC Contactors

    What is an AC contactor?

    AC contactors are used for applications that used alternating current. Their construction differs from DC contactors. Since AC power reverses the current relatively frequently, AC contactors rely on a special AC contactor coil that keeps the core from being affected by two frequencies at the same time. This coil keeps the the current steady and balances out the magnetic field created by the core.

    Switch your AC circuits with an AC contactor.

    AC contactors are used throughout a number of sectors for applications of all types. Vacuum contactors, definite purpose contactors, single phase and three phase contactors can all switch AC power. Used for HVAC systems, AC motors, heating and lighting systems, conveyors and much more, AC contactors are some of the most widely used contactors around, so whether you’re looking for an AC magnetic contactor, a solid state contactor, a single phase contactor or a 3 phase contactor, there’s an AC contactor perfect for your job.
