IMPORTANT:
This magnetic switch toggles a motor
ON
and
OFF
, and helps provide thermal overload
protection 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
current 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.
