2 HP 220V Motor

IMPORTANT: This magnetic switch toggles a motor ON and OFF, and helps provide thermal overload pro- tection for the motor if the operating temperature gradually increases due to heavy work loads. The thermal overload relay inside is not designed to cut power in the event of a sudden motor overload or stall. To help protect a motor from this type of overload, the power supply circuit must be properly sized for the full-load current rating of the motor.

OPERATION: When pushed, the green ON button on the outside cover of the magnetic switch allows cur- rent to flow to the magnetic coil, which pulls the contactor closed. The main current then passes through the thermal overload relay to the motor. If the motor begins to overheat, the relay breaks the magnetic field, which opens the contactor and cuts current to the motor. The red OFF button manually breaks the magnetic field, which opens the contactor and disconnects the current to the motor.
