INSTALLATION INSTRUCTIONS
Operating Mechanism
NOTE: For ease of assembly it might be advisable to
install the circuit breaker operator and then the circuit
breaker.
1. Remove nuts and washers from flange plate.
2. Place the operating mechanism into the enclosure with
the operating handle in the ‘Off’ position. Tilt the
assembly under the flange and at the same time bring
the handle through the slot provided.
3. Place flange plate studs through the holes in the flange
and mechanism frame while holding the assembly
against the under side of flange. Secure assembly to
flange.
4. Attach operating mechanism mounting bracket firmly
to the enclosure mounting plate surface. See line
drawing Page 1 (Bolts and spacers are furnished by
user).

mounting plate surface used to secure the circuit breaker
operating mechanism can be located previous to installa-
tion. Refer to line drawings on Page 2 .
Circuit Breaker Operator Mechanism
and Slide Mechanism
1.
Place the circuit breaker Operating Mechanism handle
in the “ON” position by first pushing the defeater
by-pass lever upward and then moving the operator
handle from “OFF” to “ON”.
2 . P l a c e c i r c u i t b r e a k e r t o g g l e l e v e r i n t h e “ O N ”
position.
3. Place circuit breaker Slide Mechanism on top of
breaker so that the slide bushings seat in the breaker
mounting holes, the toggle lever is through the slide
slot and the slot for receiving the bellcrank roller is
oriented
clockwise from the line side of the
circuit breaker terminals, as illustrated on Page 2 .

bracket, as illustrated on Page 2 .
Position circuit breaker assembly obtained in steps 3
and 4 so that the breaker line terminals are toward
the “ON” direction of the Operating Mechanism
handle and the bellcrank roller (operating mecha-
nism) is in the bellcrank slot (slide mechanism).
Align the four circuit breaker mounting screws with
the proper tapped holes in the Operating Mechanism
frame mounting surface. See illustrations on Page
2
for ITE and Westinghouse mounting.
CAUTION: Position circuit breaker so that mounting
screws are perpendicular to mounting surface and
secure the breaker to Operating Mechanism frame by
tightening the mounting screws.
NOTE: The circuit breaker can be secured onto the
Operator Mechanism mounting frame either before or
after the Operator Mechanism has been secured to the
enclosure flange.
ITE BREAKER WITH FJ FRAME AND WESTING-
HOUSE BREAKER WITH JA FRAME ONLY. Ad-
just the drive plate on the slide, per instructions
provided on Slide Mechanism.
Move Operator Mechanism handle from “ON” to
“ O F F ” a n d t h e n f r o m “ O F F ” t o “ O N ” t o e n s u r e
proper mechanical and electrical operation.
C A U T I O N : P l a c e O p e r a t o r M e c h a n i s m h a n d l e i n
“OFF” position before installation of wiring, for
maximum safety.
