General

Handle with permit locking the disconnect device in the OFF

position using up to three locks having shackles up to 3/8 in.

in dia. Provision for locking in ON position is provided/ but the

handle plate must have the material covering the locking

notch removed. This can be done with a hacksaw or file. The

handle has a voidable interlock. Voiding the interlock requires

inserting a small screwdriver into the rectangular opening in

the handle plate, which will release the handle.

A. Measure distance F from breaker mounting surface to

top surface of cover. If distance F is less than 8 in. then

remove shaft guide bracket.

B. Find length G by subtracting 5.50 in. from F dimension.

Mark length G from underside of operating plate on shaft

and cut shaft squarely at mark.

NOTE: Breaker must be “tripped” during installation. Push red

button marked PUSH TO TRIP (1).

C. Loosen the two 8-32 screws (2) that secure both terminal

shields to the breaker, remove the two .28 in. dia.

knockouts (3) and fasten circuit breaker with four 3.56

total length fastening members (4). Wire circuit breaker

and replace terminal shields. Using 1/4-20 x 11/2 in. R.H.

screws together with lockwasher and washer supplied

with kit, attach mechanism plate assembly on breaker as

shown.

D. Insert end of operating shaft into square socket in cast

operating arm so that top of shaft has proper relationship

to handle as illustrated in photograph on front of instruc-

tion sheet. (Breaker or handle may be rotated in 90

increments so long as relationship of handle and top of

operating shaft is held.) Tighten set screw in side of cast

operating arm (recommended torque—75 in. Ib.).

Handle Mounting

Holes in cover to be as shown in Figure 2. Mount handle with

cork gasket on cover and handle mounting plate on inside of

cover. Fasten together loosely through cover with the two

short screws provided. The two .31 in. dia. mounting holes

must be rotated in the same 90ø increments to maintain the

handle and operating shaft relationship. Close cover, adjust

handle with actuator to be free of binding. Tighten handle

mounting screws and operate handle ON and OFF to see that

circuit breaker operates satisfactorily.
