INSTALLATION INSTRUCTIONS
1. Place circuit breaker in off position. Position the shaft
support assembly in the Off position by turning the
mechanism counterclockwise until at a solid stop.
Place the mechanism onto the circuit breaker such
that the slot on the slider on the mechanism mates
into the breaker handle. Mount the breaker and
mechanism per the customer's application using the
necessary hardware (as shown in the chart on page
1). Evenly tighten the screws to the giv en torques (as
shown below chart on page 1).
NOTE: Before mounting the shaft support assembly
and breaker to the back pan, see installation instruction item 4 to be certain to acquire minimum front
panel dimensions for door clearance.
If mounting the breaker directly to the back of the
pan, see the figure on page 1 for mounting hole
dimensions.
CAUTION
BE CERTAIN TO CORRECTLY ASSEMBLE SHAFT
SUPPORT TO THE CIRCUIT BREAKER. FAILURE TO
DO THIS WILL CAUSE IMPROPER OPERATION AND
BREAKAGE OF PANS.
DO NOT EXCEED TORQUE LIMITS ON SCREWS.
HIGHER TORQUES COULD CAUSE CRACKING ON
THE SHAFT SUPPORT ASSEMBLY AND IMPROPER
OPERATION.
SCREW INTO BACK PAN L = C -106
L = C - 4 3/16 IN.
DIN RAIL L = C -119 MM
L = C - 4 11/16 IN.
SNAP-IN BASE PLATE L = C -108 MM
L = C - 4 1/4 IN.
Note: Dimension C is the measurement from the back
pan to the top surface of the front panel.
3. Place the shaft into the shaft support assembly as
shown on page 1 and tighten the set screw on the
collar.
4. Measure the distance from the hinge to the center of
the shaft. Measure the distance perpendicular to the
last measurement from the center of the shaft to one
of the sides of the enclosure. With the front panel
door open, mark the inside panel door with these
measurements and drill a 5/16 Dia. hole. Carefully
close the panel door and check to see if the hole is
center to shaft. From inspection of the 5/16 dia. hole,
drill a 3/8 Dia. (35mm) hole.

5. After drilling, close the door of the front panel and
place the full size cutout template on the front panel.
Center the template over the shaft and align the top
edge of the template so that it is parallel with the line
end of the breaker . Mark the handle screw holes and
drill (2) 7/32 Dia. (5.5mm) holes as indicated on the
template.
6. Apply the mounting screws to door and handle.
7. With main power Off, check the mechanism opera-
tion in the On, Off, and reset positions.
