IMPORTANT: This magnetic switch toggles a motor ON and OFF, and helps

provide thermal overload protection for the motor if 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, this magnetic switch MUST be connected to a properly sized

power supply circuit with a correct fuse or circuit breaker.

OPERATION: The green push button switch allows current to go to the magnetic coil which pulls the contactor

closed. Main current now passes through the thermal overload relay and then to the motor. This relay monitors

motor current draw. If the motor begins to overheat, this relay breaks the magnetic field, which opens the

contactor and cuts current to the motor. The red push button breaks the magnetic field, which opens the

contactor and disconnects the current to the motor.
