Thermal Relay Overload
Amp Adjustment Dial:
Turn this dial to meet your
motor manufacturer's
thermal overload amp setting
specification. Typically this
setting is 100-110% of what is
listed on the motor data plate as
the max amp load. Remember,
turning this dial has no effect on
increasing motor horsepower.
If this dial is turned to an amp
setting that is too high, the
motor can overheat and be
damaged before the relay
trips.
Trip Indicator: If the window
is flagged yellow, the thermal
relay has tripped.
Manual Trip Test Lever:
If the thermal relay function
is in question, 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.
ON Button:
When pushed, power is sent
to the magnetic field coil and
the contactor closes and
sends power to the motor.
Manual/Auto Reset Lever:
In the up position, the
thermal relay is in manual
reset mode, where if tripped,
you must first push the
red and then the green
ON button reset button
on the outside of the main
cover 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 and the
yellow flag shown in the trip
indicator window is cleared.
Manual Contactor Override Lug:
When pushed, the contactor is
manually closed for troubleshooting
purposes only.
OFF Button:
When pushed, the current going to the magnetic field coil is cut, which
opens the contactor and cuts power to the motor.
