G4573 Magnetic Switch
Thermal Relay Overload Amp
Adjustment Dial: Turn this dial
to the amperage setting speci-
fied by the motor manufacturer.
Typically, this setting is 100–
110% of the amperage load listed
on the motor data plate. Please
note that turning this dial has
no effect on increasing motor
horsepower. If turned too high,
the motor can overheat and be
damaged before the relay trips.
Trip Indicator: If this window
turns yellow, the thermal relay
has tripped.
Manual Trip Test Lever: If the
thermal relay function is in ques-
tion, run the motor and use a
wooden toothpick to slide the
yellow test lever to the left. If the
motor shuts off, the thermal relay
has tripped and is functional.
OFF Button: When pushed, the current going to the magnetic field
coil is cut, which opens the contactor and cuts power to the motor.
When pushed, the contactor
is manually closed for trouble-
shooting purposes only.
ON Button: When pushed,
power is sent to the magnetic
field coil, closing the contactor
and sending power to the motor.
Manual/Auto Reset Lever: In
the up position, the thermal relay
is in manual reset mode. This
means you must re-install the
outside cover and push the red
OFF button, then push the green
ON button to reset the thermal
relay. In the down position, the
thermal relay will automatically
reset when it has cooled.
Reset Button: When pushed,
the thermal relay is reset, clear-
ing the yellow trip indicator win-
dow.
