1. INTRODUCTION
General Information
The shunt trip (Fig. provides remote controlled elec -
trical tripping for the circuit breaker. It consists of an inter -
mittent rated solenoid with a tripping plunger and a cutoff
switch attached to a plug
- in module. The plug - in module
is mounted in slots in the accessory mounting deck in the
right pole of the circuit breaker. When the solenoid is
energized, the plunger extends and presses against the
trip bar. As the circuit breaker trips, the molded trip bar
rotates and allows the cutoff switch to open, disconnect
-
ing power to the solenoid and preventing coil burn out.
Table
1 - 1 lists application and electrical operating ratings
data for the shunt trip.
Fig. 1-1 Shunt Trip Installed in R-FrameCircuit Breaker.
The standard wiring configuration for the shunt trip is pig -
tail leads exiting the right side of the cover. An optional
terminal block (Cat No. TBRD) may be mounted to the
right side of the circuit breaker to terminate attachment
ieads. The 18
- inch (457.2 mm) long pigtail leads are color
identification; numbered identification labels are
provided for pigtail leads.
This instruction leaflet (IL) gives detailed procedures for
installing the shunt trip.
Note:The shunt tr i p can be field installed in RD
and RDC circuit breakers under UL File E64983.
The shunt trip can be fieid - installed in RW and RWC
circuit breakers.
The
UL File E7819.
shunt
trip is listed for factory installation under
Before attempting to install the shunt
trip, check that
the catalog number
is correct as ordered and that the
rating of the accessory satisfies job requirements.
The shunt trip, shown in kit form in Fig. 2 - 1, is installed in
the right pole
of a 3 - or 4 - pole circuit breaker. To install
the shunt trip, perform the following procedures:

WARNING
THE VOLTAGES IN ENERGIZED EQUIPMENT CAN
CAUSE DEATH OR SEVERE PERSONAL INJURY.
SPECIAL ATTENTION SHOULD BE PAID TO
REVERSE FEED APPLICATIONS TO ENSURE
NO
VOLTAGE IS PRESENT. BEFORE MOUNTING THE
SHUNT TRIP IN A CIRCUIT BREAKERINSTALLED
IN
AN ELECTRICAL SYSTEM, MAKE SURE THE CIR -
CUIT BREAKER IS SWITCHED TO THE OFF POSI-
TION AND THERE IS NO VOLTAGE PRESENT
WHERE WORK IS TO BE PERFORMED.
Note: Internal accessories are most easily installed
in
a circuit breaker before it is mounted in an elect-
ri
cal system. Although it is recommended that a cir-
cuit
breaker mountedin an electricalsystembe rem-
oved to install accessories, it is possible to perform
this task in
a mounted circuit breaker provided no
voltage
is present and proper safety precautions
are followed.
2-1. Switch circuit breaker to OFF position.
Note:To install accessory, circuit breaker must be
in tripped position.

Remove cover screws and cover.
2 - 4. Install shunt trip as described in following steps:
Note: For ease of installation auxiliary switch acces -
sories (if used) should be installed in the accessory
mounting deck before the shunt trip or
other acces -
sories.
a. Select position for shunt trip on accessory mounting
deck (see Fig
2 - 2).
b. Place legs of shunt trip mounting bracket into slots in
accessory mounting deck.
c. Slide the shunt trip toward the line end of the circuit
breaker until the retaining clip snaps into recess in
deck (see Fig.
2 - 3).
If installing more than one shunt trip, attach a num -
bered wire marking label to each set of leads.
Labels marked and
" 2 " are provided to allow for
the installation of up to the maximum of two shunt
trips.
PIGTAIL LEADS COULD BE DAMAGED IF IN CON -
TACT WITH MOVING PARTS. PIGTAIL LEADS
SHOULD BE FORMED AND ROUTED
TO CLEAR ALL
MOVING PARTS
WHEN ACCESSORY IS PROPERLY
INSTALLED.
Attach cable tie mounting pad to side of circuit
breaker (See Fig.
2 - 4 for location). Route leads to
mounting pad. Ensure leads line up with slot
in
cover and are clear of all moving parts. Secure
leads to mounting pad with cable tie. Leads from
multiple accessories may be secured by a single
cable tie and mounting pad (see Fig.
2 - 3).
Remove barrier indicated in Fig. 2 - 4 from cover
accessory lead slot.
WHEN CHECKING ACCESSORY, DO NOT PUT FIN -
GERS NEAR MOVING PARTS INSIDE THE CIRCUIT
BREAKER CASE. SPRINGS CAUSE INTERNAL
PARTS TO MOVE QUICKLY AND WITH FORCE.
CON -
TACT WITH MOVING PARTS CAN CAUSE INJURY.

Note:The circuit breaker's cover interlock will pre -
vent the breaker from being latched while th e cover
is removed.T he interlock consists of
a spring load-
ed lever pivoting on the right side plate just below
the handle (see
Fig. 2-3). Use a tool t o depress and
hold the lever even wi th
the top of the circuit break-
er base while performing mechanical tests.
Perform mechanical check of shunt trip after instal -
lation:
a. With the circuit breaker still electrically isolated,
depress the cover interlock lever and reset circuit
breaker.
b. Using a small flat
- blade screwdriver, depress shunt
trip plunger (Fig. 2
- 3). Circuit breaker should move to
trip position.
c. If mechanical check does not trip circuit breaker, see
if shunt trip is correctly installed. If shunt trip appears
to be properly installed and problem persists, contact
Eaton.
Test cutoff switch. Connect ohmmeter across pigtail
leads or terminal block connections. Check continu
-
ity as follows:
a. Circuit breaker tripped no continuity.
b. Circuit breaker closed less than 9000 ohms.
(Depress cover interlock lever to close breaker) Cir
-
cuit breaker opened - less than 9000 ohms.
c.
If cutoff switch fails test, make sure that shunt trip
module is properly seated in mounting deck slots.
problem persists contact Eaton.
CAUTION
WHEN INSTALLING CIRCUIT BREAKER COVER,
MAKE SURE
THAT PIGTAIL LEADS ARE CLEAR OF
THE COVER.
2 - 10. With circuit breaker handle in tripped position and
accessory pigtail leads routed as required, install
circuit breaker cover.
2 - 1 1. Position accessory labels supplied with kit on cir -
cuit breaker as shown in Fig. 2-4.
Note: Accessory labels show connection diagram
for shunt trip. Pigtail leads are color coded white
and yellow.
2 - 12. Install circuit breaker. Torque cover screws to
24 in - lbs (2.71 Nm).
2 - 13. Connect shunt trip as required (see Fig. 2 - 5).
