2. Installation
For assembly steps, refer to Figure 1, unless otherwise noted.
1. For a single breaker, mount the breaker with four stand-offs and
lock washers. For dual breakers, mount each breaker with two
standoffs and lock washers (inner mounting holes of the breaker)
and two mounting screws and lock washers (outer mounting
holes of the breaker). Tighten 28 in.-lb (3.16 N
●
m).

2. Install the handle to the enclosure by removing the two screws
and lock washers from the outer handle mechanism. Place the
outer handle mechanism with attached gasket over the enclosure
cut-out (for cut- out dimensions, refer to Figure 7). Insert the top
¼-20 outer handle mechanism mounting screw and lock washer
through the enclosure and thread into the outer handle mecha-
nism for a few turns, but not all the way.
3. Slide the toggle mechanism assembly over the top of the handle
mounting screw. Insert the bottom outer handle mechanism
mounting screw and lock washer through the toggle mechanism
bracket, through the enclosure, then into the handle. Tighten
both mounting screws 23 - 37 in.-lb (2.60 -4.18 N
●
m) maximum.
4. Rotate the bell crank towards the handle and rotate the outer
handle to the “ON” position. Align the actuator link (hole that is
marked “1”) and attach it to the bell crank.. Secure it using an
E-Ring (see Figure 5).
5. Connect the long end of the spring through hole in handle actua-
tor link. Hook the shorter end of the spring into the tab on the
lower portion of the toggle mechanism (see Figure 6).

6. Put outer handle mechanism in the “TRIP” position for ease of
mounting the actuator mechanism.
7. Mount the actuator mechanism to the breaker. Insert the four
#8-32 x .50 screws and lock washers through the mechanism
and into the standoffs. Tighten 28 in.-lb (3.16 N
●
m).
8. Mount the door interlock pin and lock washer to handle. Tighten
23 - 37 in.-lb (2.60 - 4.18 N
●
m).
9. Operate the handle mechanism to ensure functionality. To oper-
ate, either close the door or defeat the door interlock lever.
10. If minor adjustments are necessary, refer to the “Adjustment
Checklist” in Section 3.
11. Install the appropriate door hardware (supplied) (see Figure 7).
