INTRODUCTION

The motor operator (Fig.

be opened, closed, or reset remotely. It has the capability

for lock

off, push

trip, and manual operation. Electrical

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.

change wire leads, just pull out the wire connector,

and connect the new wire leads to the screws or

tabs of the terminal block. (See Fig. 2

OPERATION

Note: The motor operator does not permit a breaker

handle to indicate

its

“TRIP” position. If

desir

able that the

trip

position be indicated, the breaker

may be equipped with bell alarm contacts which

“MAKE” or “BREAK” upon automatic trip operation.

Contacts may be wired

an external

light

or other

indicating device to then indicate trip.

2).

2. Energizing the “OFF” push button will cause the

breaker to go to its “OFF” position.

3. Energizing the “ON” push button will cause the

breaker to go to its “ON” position.

4. Press the “PUSH

TRIP” button (see Fig. 3

energizes the motor when

the carriage has moved sufficiently to close the circuit

breaker. The lower switch de

energizes the motor when

the carriage has moved sufficiently to reset the circuit

breaker.

1. Disconnect the motor operator from the supply volt

age.

2. Remove the cover screws and the motor operator

cover.

3. Use a .125-in. dia. pin (customer supplied) and

insert into the 30

CAUTION

.125 IN. DIA. PIN SHOULD BE REMOVED BEFORE

REINSTALLING THE COVER.

4. For upper limit switch adjustment, loosen the two

travel. Move the switch down to decrease the car

riage travel. After adjusting, tighten the screws.
