Assembly
1. Unpack the circuit breaker and inspect it for any
shipping damage. Ensure that the breaker has
the proper ampere range, sensor rating, voltage
rating, and interruption rating for the application.
Since this breaker is available in a wide variety of
configurations, compare the catalog number of your
purchased breaker with the catalog number key in
Table 1. Installation of an incorrect breaker could
result in misapplication, lack of system coordination,
or reduction in system functionality.

4. Attach the terminal lugs, listed in Table 4, following the
instructions supplied with the lug kit. Use one kit for
either line or load end; two kits are required for both.
WARNING: It is important that the terminal covers are
installed correctly to ensure proper circuit breaker
operation.
IMPORTANT: Il est important de vérifier que tous
couvercles ou caches de protection sont correctement
installés afin d’assurer le bon fonctionnement de
l’appareil.
6. Finally, connect all associated components that are
required for the breaker to function properly, using
the instructions supplied with each component.

NOTE: Trip units as received may have settings that are
undesirable for the specific application. Ensure that
settings are appropriately adjusted before energizing
the breaker.
Operation
The circuit breaker status is indicated by ON/OFF
markings, universal I/O symbols, and an indicator
window that shows red for ON, yellow for TRIP, and
green for OFF. The corresponding handle positions are
illustrated in Figure 2. To close the breaker from the
OFF position, move the handle to the ON position. To
close the breaker from the TRIP position, first move the
handle to the OFF (reset) position, and then back to the
ON position.
A Push-To-Trip button is provided for convenience in
testing the mechanical operation of the breaker.

It is recommended that the following operations be
performed annually:
External Accessories
The following external accessories are available for
Spectra RMS SK Frame breakers. Catalog numbers
and other ordering information for these external
accessories may be obtained from your authorized GE
distributor.
• Mounting kits
• Plug-in base, bolt-on base
• Back-connected studs
• Padlocking devices
• External Handle operator
• Motor operators

1. Turn off the power to the equipment being serviced.
2. Clean the surfaces of the breaker and surrounding
area of any dirt, soot, or other debris.
3. Inspect the breaker for any signs of damage.
4. Operate the push-to-trip button and toggle handle
several times to exercise the mechanism and test
the mechanical operation of the breaker.
