    For reliable and efficient three phase switching.

    Used in 3 phase AC applications, three phase contactors switch and control high current electrical circuits. All 3 phase contactors are AC contactors since phasing is a characteristic of AC power. 3 phase magnetic contactors are used in HVAC, heating and lighting applications among many others. 3 phase contactors are built for 3 phase motor use; however, they can be used for single phase motors if you rewire the connections. Although it is more economical to use 3 phase contactors and single phase contactors with their respective motors. When you combine a 3 phase contactor with an overload, you get a three phase starter.

    Types of three phase contactors.

    Three phase contactors are built rugged to accommodate the demands of 3 phase motor circuits. 3 pole contactors can be definite purpose contactors or general purpose and are available across a number of current ratings. Three pole 30A, 40A, 50A, 60A and even 100A contactors are all popular configurations. Most three phase contactors utilize 120V coils or 240V coils though they can utilize coils as high as 600V depending on the horsepower rating.
