How to Wire a Contactor: 8 Steps (with Pictures)

Many large pieces of equipment are powered directly from high voltage lines. These lines far exceed the 120 volts AC standard in most homes. 240 volts AC and 480 volts AC are commonly used for these large pieces of equipment, such as motors, industrial machines, and large household appliances like washers and dryers.

Wiring Diagram For A Starter Controlling A 480v Motor With 120v Start/stop Button. Of course the coil voltage must be and the motor can be whatever voltage, this with a PLC output straight to a starter and get rid of the Start/Stop switch. To add an additional remote station wire the new STOP button in series with the.

How to Wire a Three

Contactors are typically used on three-phase air conditioning motors requiring at least 480 volts to operate. These devices do not use a physical switch for switching. A contactor uses a low-voltage signal to control the high-voltage circuit. This low-voltage signal can be controlled by an electrical relay or a computer.
