for Series NRX fixed breaker
mounting feet
WARNING
(1) ONLY QUALIFIED ELECTRICAL PERSONNEL SHOULD BE PERMITTED TO
WORK ON THE EQUIPMENT.
(2) ALWAYS DE-ENERGIZE PRIMARY AND SECONDARY CIRCUITS IF A
CIRCUIT BREAKER CANNOT BE REMOVED TO A SAFE WORK LOCATION.
(3) DRAWOUT CIRCUIT BREAKERS SHOULD BE LEVERED (RACKED) OUT TO
THE DISCONNECT POSITION.
(4) ALL CIRCUIT BREAKERS SHOULD BE SWITCHED TO THE OFF POSITION
AND MECHANISM SPRINGS DISCHARGED. FAILURE
TO FOLLOW THESE
STEPS FOR ALL PROCEDURES
DESCRIBED IN THIS INSTRUCTION LEAFLET
COULD RESULT IN DEATH, BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
THE INSTRUCTIONS CONTAINED IN THIS IL AND ON PRODUCT LABELS
HAVE TO BE FOLLOWED. OBSERVE THE FIVE SAFETY RULES:
– DISCONNECTING
– ENSURE THAT DEVICES CANNOT BE
ACCIDENTALLY RESTARTED
– VERIFY ISOLATION FROM THE SUPPLY
– EARTHING AND SHORT-CIRCUITING
– COVERING OR PROVIDING BARRIERS TO
ADJACENT LIVE PARTS
DISCONNECT THE EQUIPMENT FROM THE SUPPLY. USE ONLY
AUTHORIZED SPARE PARTS IN THE REPAIR OF THE EQUIPMENT. THE
SPECIFIED MAINTENANCE INTERVALS AS WELL AS THE INSTRUCTIONS
FOR REPAIR
AND EXCHANGE MUST BE STRICTLY ADHERED TO PREVENT
INJURY TO PERSONNEL AND DAMAGE TO THE SWITCHBOARD.
Section 1: General information
Rear connected fixed circuit breakers can be mounted on a
suitable horizontal or vertical mounting surface using a pair of
left and right side mounting feet. In addition, front-connected
fixed circuit breakers can also use the mounting feet for
mounting a breaker on a suitable vertical surface, although
this is not the most common method used.
Seven pieces of mounting hardware are provided to mount
the pair of mounting feet (five M5 x 12 mounting screws, one
M5 x 25 mounting bolt, and one M5 nut). The M5 x 25 bolt,
and M5 nut are used with the right side mounting foot only to
ground (earth) the mounting foot to the breaker mechanism.
One mounting hole and one slot are provided in each mount-
ing foot for attaching the circuit breaker to an appropriate
horizontal mounting surface. Two mounting slots are provided
in each mounting foot for attaching the circuit breaker to an
appropriate vertical mounting surface. M8 or 5/16-inch mount-
ing hardware is recommended for mounting the breaker, and
is provided by the customer (Figure 1).

information.

Section 2: Mounting feet installation
To install the mounting feet, proceed with the following six
steps:
Step 1: Remove the four screws holding the front cover in
place (two on each side of the cover).
Figure 4. Step 1
Step 2: Remove the front cover. Pull down on the charging
handle to simplify removal.
Figure 5. Step 2
Step 3: Line up the three mounting holes in the right side
mounting foot with the mounting holes in the right side of
the circuit breaker. Use two M5 x 12 screws, one M5 x 25
mounting bolt, and one M5 nut of the mounting hardware
provided to attach the right side mounting foot to the right
side of the breaker. The M5 x 25 mounting bolt and M5 nut
are used in the lower front mounting hole, and provide for a
grounding (earthing) connection to the breaker mechanism.
The M5 x 25 bolt goes through the side of the breaker hous-
ing and is secured from the inside by the M5 nut. Grounding
(earthing) is not required for UL 489 product only. The M5
x 25 bolt with M5 nut are still used on UL 489 product to
attach the mounting foot to the frame only. The two M5
x 12 screws are used in the upper mounting holes. Once all
mounting hardware is in place, complete the process by tight-
ening the mounting hardware to 5–6 ft-lbs (6.6–8.1 Nm).

Step 4: Once mounted, the right mounting foot should look
as shown.
Figure 7. Step 4
Step 5: The left side mounting foot is then mounted in a
similar fashion to that just described in Steps 3 and 4 using
the three remaining M5 x 12 mounting screws. Torque these
screws to 5–6 ft-lbs (6.6–8.1 Nm) also.
Step 6: Replace the front cover and secure it in place with
the four mounting screws previously removed in Step 1.
Section 3: Mounting
feet removal
To remove the mounting feet, reverse the procedure just
