General Information
When properly installed, the rotary handle operator provides
single point latching of the enclosure door For maximum
protection against unauthorized entry into the enclosure,
additional latching means should be provided. The handle can
be padlocked in the OFF position with up to three 5/16 in.
padlocks. The breaker operator can also be padlocked in the
OFF position.
Drilling of Enclosure
A. Catalog number RHOSSD standard depth shafts are
used for minimum depth enclosures. Refer to minimum
dimension K in Figure 2. Catalog Number RHOSVD
variable depth shafts are used for all other enclosure
depths. Shafts are cut to length L as shown in Figure 4.
B. Drill and tap circuit breaker mounting holes in breaker
mounting surface (1) and handle mounting holes in enclo-
sure door (2) as shown in Figure 1.
Installation of Breaker and Breaker Operator
(RHOJBO)
A. Remove the two terminal shields (3) from the circuit
breaker and punch or drill out the two .53 in. dia.
knockouts.
NOTE: Cut slots in terminal shields as shown to allow access
to terminal lugs after installation of breaker operator
without prior removal of mechanism.
Caution: Replace the terminal shields.
B. Mount circuit breaker to enclosure panel using the four
breaker mounting screws (4) as shown. Tighten to 75 in.
lb.
C. Insert spacers (5) into the four circuit breaker mounting
holes and attach the breaker operator (6) using the four
1/4-20 X 1-3/4 in. mounting screws (7) and 1/4 in.
lockwashers (8) as shown. Tighten to 75 in. lb.
Installation of Shaft (RHOSSD, RHOSVD)
A. Shaft length for Variable Depth Operators L = K - 3.61 in.
Attach the shaft (9) to the operating arm (10) of the
breaker operator and tighten the set screw to 70 in. lb.
min.
NOTE: The proper orientation of the “wings” (11) (shown in off
position) at the end of the shaft when the breaker is in the
OFF position (Figure 4).
NOTE: It is recommended that the shaft support bracket (12)
be installed if the enclosure depth exceeds 10 in. Attach
as shown in Figure 3. Tighten to 45 in. Ib.
Installation of Handle (RHOH, RHOH4)
A. Attach the handle (13) and gasket (14) to the enclosure
door (2) and secure with the four bolts, lockwashers and
nuts supplied (15). Tighten to 75 in. Ib. (Figure 5).
B. Make sure that when the enclosure door is closed, the
handle interlocks with the shaft in all handle positions
except RESET/OPEN. To open the enclosure door when
the breaker is in the ON position, rotate the screw slot on
the handle plate counterclockwise. This procedure will
defeat the interlock.
C. To lock the handle in the OFF position, pull the lock plate
(16) from the handle into the grooves on the handle plate
(17) located at the interlock defeater screw and insert the
padlocks.
D. The unit can be modified to lock in the ON position by
cutting slots in the boss located beneath the letters ON.
NOTE: The score lines on the inside diameter below the letters
ON indicate the slot locations.
