This is a magnetic control for single phase motors. The main reason to use one of these is safety. If the power goes off with a magnetic control the motor will not restart unless you press the on button again. It will not turn on when the power is restored, only when the on button is pressed. This control is three phase, 220-240v, up to 5 hp, and adjustable for 12-18 amps. The wiring diagram is inside the cover. It uses standard US style wiring connectors.
