1-0 INTRODUCTION
The motor operator (Figure 1-1) allows the circuit break-
er to be opened, closed, or reset remotely. It has the
is removed.
The motor operator mechanism is driven by a reversible
electric motor connected to a ball screw. The ball screw
drives the circuit breaker handle. Limit switches are
used to control the motor.
2-0 INSTALLATION
The motor operator is UL listed and suitable for field
Figure 1-1 Motor Operator Installed on L-Frame Series C
Circuit Breaker
!WARNING
If the motor operator is to be installed on an OPTIM
breaker, an OPTIM Connector Kit, Catalog Number
OPEOPCK, should be ordered to allow the Optimizer to
be connected on the face of the operator. The kit
includes a connector socket and an extension cable to
the trip unit port.
The motor operator is normally supplied as a separate
item for mounting on an uninstalled circuit breaker. If a
motor operator is to be mounted on an installed circuit
breaker, all power must be removed from the circuit
breaker before proceeding to mount the motor operator.
!WARNING
installation on L & MDL-frame circuit breakers and
molded case switches under UL File E64124.
BEFORE MOUNTING A MOTOR OPERATOR ON A
CIRCUIT BREAKER INSTALLED IN AN ELECTRICAL
SYSTEM, MAKE SURE THE CIRCUIT BREAKER IS
SWITCHED TO THE OFF POSITION AND THAT
THERE IS NO VOLTAGE PRESENT WHERE WORK
IS TO BE PERFORMED. SPECIAL ATTENTION

TIONS TO ENSURE NO VOLTAGE IS PRESENT.
THE VOLTAGES IN ENERGIZED EQUIPMENT CAN
CAUSE INJURY OR DEATH.
ENERGIZING THE MOTOR OPERATOR WHEN IT IS
NOT MOUNTED TO A CIRCUIT BREAKER MAY
DAMAGE IT. ENSURE THAT THE MOTOR OPERA-
TOR IS SECURELY MOUNTED TO A CIRCUIT
BREAKER BEFORE OPERATING ELECTRICALLY.
A minimum 1 Kva power source is recommended
for motor operator.
When the circuit breaker is already installed, the
existing hardware must be replaced.
When the motor operator is mounted to the circuit
breaker, the circuit breaker nameplate is not visible.
Before mounting the motor operator, make sure the
circuit breaker nameplate information is recorded
for future reference. A blank nameplate is supplied
for this purpose. The nameplate should be placed
on the top side of the motor operator.
The installation procedure consists of inspecting the
motor operator for completeness and mounting the
motor operator to the circuit breaker and connecting the
control wires. To install the electrical operator perform
the following steps:
2-1. Remove motor operator from packing. Inspect it
for completeness (Figure 2-1). Check the motor opera-
tor nameplate to make sure that the rating agrees with
the installation requirements; and make sure that
mounting hardware is included.
The motor operator is suitable for application with 3 and
4 pole series C circuit breaker types LDB, LD, HLD,
LDC, LW, HLW, MDL, LWC, plus LA circuit breaker
family.
2-2. Install circuit breaker handle extension using 3
thread cutting screws supplied. Torque screws to
2-3. The breaker must be mounted with special studs
(Figure 2-1) supplied. If the circuit breaker is already
installed, replace mounting hardware. (At least one of
the studs must be grounded to insure that the motor

2-4 For L-Frame Mount breaker with (4)
special mounting studs supplied. Assemble
mounting clamp to the studs on line end of
the breaker using the (2) 10-32 x 1.50” flat
head screws supplied.
For MDL-Frame: Remove (4) breaker cover
screws. Insert keyhole clamp into line-end,
right side cover screw hole above the
breaker handle.
2-5 For L-Frame turn breaker to the “Off”
position. Attach the handle extension from
the parts kit. Mount the motor operator to
the circuit breaker using (2) 10-32 x 7/16”
long screws and lock washers on the line
end and using (2) 10-32 x 1.5” long screws
and lock washers on the load end.
For MDL-Frame turn breaker to the “Off
position. Attach the handle extension from
the parts kit. Mount the motor operator by
placing the keyhole slot in the motor
operator frame over the keyhole clamp and
sliding it into position. Install the (3) 8-32 x
2.25” button head screws in the remaining
cover holes from step 2-4.
Torque each screw to 20-22 lb-in (2.26-2.49
N-m). The handle extension must be located
between the rollers of the operator bracket
assembly, and the motor end of the operator
is positioned towards the line end of the
breaker (Figure 4-1).
2-6 The motor operator is equipped with
two “PUSH-TO-TRIP” actuators for use on
either solid state (left hand actuated) or
thermal magnetic (right hand actuated) trip
units. Mount the red “PUSH-TO-TRIP”
BUTTON MOLDING TO THE CORRECT
ACTUATOR USING THE (2) 4-40 X .25
LONG SEMS SCREWS SUPPLIED. Then
turn on the circuit breaker, press the “PUSH-
TO-START” button, to verify the breaker
trips.
2-7 To connect the power and control
wiring, refer to (figure 2-2).
2-8 Replace the motor operator cover and
screws. If dust cover sliders become
separated from the operator cover, they
must be installed in a proper orientation.
Viewing the cover from the rear with the
“PUSH-TO-TRIP ” slot on the bottom. The
smaller plate is placed on the medium plate
which is placed on the longest plate, then to
the inner cover surface located under the
guide rails
2-9 To verify the manual operation of the
motor operator, refer to paragraphs 3.5 to
3.7.
2-10 To verify the electrical operation of the
motor operator, refer to paragraphs 3.1 to
3.4.
2-11 To adjust the motor operator if it fails to
fully open, close or reset the circuit breaker
during the electrical operation, refer to
paragraphs 4.1 to 4.5.

3-0 OPERATION
The following procedures describe the operation of the
electrical operator and addresses electrical operation,
The motor operator does not permit a breaker handle to
indicate its “TRIP” position. If it is desirable that the trip
position be indicated either of the following two methods
may be incorporated:
1. The breaker may be equipped with bell alarm con-
tacts which “MAKE” or “BREAK” upon automatic trip
operation. Contacts may be wired to an external light or
other indicating device to then indicate trip.
MAKE SURE THAT ALL SENSITIVE EQUIPMENT
CONNECTED TO THE LOAD SIDE OF THE CIRCUIT
BREAKER IS DISCONNECTED BEFORE OPERAT-
ING THE MOTOR OPERATOR. SWITCHING OPERA-
TIONS COULD CAUSE DAMAGE TO EQUIPMENT -
ESPECIALLY EQUIPMENT REQUIRING A CON-
TROLLED SHUTDOWN.
!CAUTION
DO NOT EXCEED THE DUTY CYCLE OF “OFF” TO
“ON” TO “OFF” AT ONE PER MINUTE. EXCEEDING
THE MAXIMUM OPERATING RATE CAN DAMAGE
THE MOTOR OPERATOR.
DO NOT CONNECT THE MOTOR OPERATOR TO
VOLTAGES ABOVE THE RATED VOLTAGE OF THE
DEVICE. VOLTAGES THAT EXCEED THE RATED
VOLTAGE CAN CAUSE DAMAGE.
Electrical Operation
To check the electrical operation use the remote
momentary “ON” and “OFF” control devices, and per-
form the following steps: (refer to Fig. 2-2)
3-1. Pull up on the setting pin and slide the locking arm
(white line) to the Electrical Operation mode. (Figures
3-1 and 3-2)
3-2. Energizing the “OFF” pushbutton will cause the
breaker to go to its “OFF” position.
3-3. Energizing the “ON” pushbutton will cause the
breaker go to its “ON” position.
3-4. Press the “PUSH-TO-TRIP” button (see Figure
3-1); verify that the breaker trips. Energizing the “OFF”
button, motor operator will “RESET” the breaker.

4-0 ADJUSTMENT
The following procedures describe the adjustment of the
motor operator limit switches if necessary:
The motor operator has been adjusted at the facto-
ry. Before attempting to adjust the motor operator,
verify that a 1 Kva power source is being used and
that all installation instructions above been fol-
lowed. Verify that the circuit breaker can be operat-
ed without the motor operator. Under standard con-
adjustment.
Two limit switches control the travel of the motor opera-
tor carriage. The upper switches control the travel of
the motor operator carriage. The upper switch de-ener-
gizes the motor operator when the carriage has moved
4-1. Disconnect the motor operator from the supply
voltage.
4-2. Remove the cover screws and the motor operator
cover.
TAPE SHOULD BE REMOVED BEFORE
REINSTALLING THE COVER.
4-4. For upper limit switch adjustment, loosen the two
pan head screws securing the upper switch assembly.
Move the switch up to increase the carriage travel.
Move the switch down to decrease the carriage travel.
After adjusting, tighten the screws.
4-5. For lower limit switch adjustment, loosen the two
pan head screws securing the lower limit switch assem-
bly. Move the switch down to increase the carriage
travel. Move the switch up to decrease the carriage
travel. After adjusting, tighten the screws.
