INTRODUCTION
Service Information S275-10-3 provides maintenance instructions for the Type Cl three-phase fault interrupter. Included is a
general description of the interrupter and control, and their operation. A service parts list, keyed to exploded-view drawings of
the interrupter, is included at the back of the manual.
DESCRIPTION
The Type Cl fault interrupter (Figure 1) is an automatic, nonreclosing, three-phase interrupting device that will interrupt currents through 12000 amps symmetrical on systems rated
through 38 kv. A compact, lightweight device, the Type Cl features submersible construction, a stored-energy mechanism,
and dry, solid insulated vacuum interrupters.
Line currents are sensed by 1000:1 ratio encapsulated bushing current transformers on each phase on the interrupter. This
provides a continuous measurement of phase and ground current, which is monitored by the Electronic Trip Control. When

87863KMA
the selected minimum-trip current value is exceeded, and after a time
delay, the control sends a trip signal to the interrupter operating mechanism. Control operating power is also obtained from the BCT’s; thus
no external power is required for timing or trip functions. The control is
easily programmed for various minimum trip values and time-current
characteristics on both phase and ground.
The integral galvanized-steel mounting frame with predrilled mounting holes facilitates wall, floor, or ceiling mounting. The electronic control, enclosed in a weatherproof (nonsubmersible) cabinet and connected to the interrupter through two shielded plug-in cables, can be
mounted on either side of the interrupter frame or at a remote location
up to 100 feet away.
High-voltage connections are made to either 200 amp universal
bushing wells or 600 amp bushings depending on the continuous current rating of the unit selected. Both are molded as an integral part of
the solid insulation system, and they interface with industry-standard
200 amp loadbreak and nonloadbreak bushing plug inserts or 600
amp shielded cable connectors.
These instructions do not claim to cover all details or variations in the equipment, procedure, or process described, nor to provide direction for
meeting every possible contingency during installation, operation, or maintenance. When additional information is desired to satisfy a problem not
covered sufficiently for the user’s purpose, please contact your Cooper Power Systems sales engineer.

Interrupter contact opening and closing is through release of
stored-spring energy. Both the opening and closing springs are
charged by a 120 volt ac motor which runs automatically
immediately after each opening operation. A push-pull spring
charging feature permits manual spring charging should motor
power be lost.
In addition to automatic tripping on fault current, the Type Cl
interrupter can be tripped with a remote contact, with the manual operated switch on the control panel, or with the mechanically-linked trip-reset lever, on the front of the mechanism tank.
It can be closed with a remote contact, with the manual control
switch on the panel, or with the mechanically-linked close lever
at the front of the tank.

Operations
Fault Interrupters for AC Systems,” it is recommended that the
following maintenance procedures must be performed yearly, or
at the completion of an equivalent duty cycle.
• However, in the absence of specific operating experience, it
is recommended that an external inspection be made on a
yearly basis. (See “Maintenance Procedure” below.)
Periodic Maintenance Inspection
Each periodic maintenance inspection, done at the completion
of an equivalent duty cycle, should include:
1. Bypass and remove interrupter from service.
2. Inspect external components.
A. Check for broken or cracked interrupters. Replace as
necessary.
B. Check for scratched paint, repaint as needed.
C. Note counter reading and enter in the record log.
3. Perform an insulation level withstand test.
4. Remove tank to expose internal components.
5. Oil fills the cavity around the moving contact operator rod. If
oil or oil residue is observed within the tank, carefully
inspect the base of each interrupter to determine the source
of the leak. If an interrupter is leaking, it should be returned
to the factory for repair.
6. Clean internal components.
CAUTION
Never use volatile solutions, detergents, or water-soluble
cleaners.
7. Check contact erosion of the vacuum interrupters. With the
contacts closed the dimension between the support plate and
boss, see Figure 2, should not exceed 5/8".
MAINTENANCE
Frequency of Maintenance
Because interrupters are applied under widely varying operating and climatic conditions, maintenance intervals are best
determined by the user based on actual operating experience.
To assure proper operation, interrupters must be maintained
when they have operated the equivalent of a complete duty
cycle and before the dielectric strength has deteriorated below
prescribed levels. In the absence of specific operating experience, the following procedures are recommended.
• When Type Cl interrupters are operated under usual service
conditions as defined in ANSI (American National Standards
Institute) C37.60,’`Requirements for overhead, Pad
Mounted, Dry Vault, and Submersible Automatic Circuit
Reclosers and

8. Check circuit components attached to the operating
mechanism.
A. Check condition of wiring to terminal strips and
make sure all connections are tight.
B. Check condition and operation of all microswitches
and trip solenoids.
C. Check condition of current transformers and the
associated wiring, if equipped.
9. Replace tank gasket. Apply quick-set adhesive to position and hold gasket in groove at corners of tank.
10. Check the tightness of all cable connectors and other
fastners.
11. Clean gasket seat and retank the interrupter. Replace
the head bolts and tighten to 10-15 ft-lbs. torque. Apply
clamping force gradually and equally, in rotation, to
each bolt to achieve an evenly distributed gasket sealing pressure. Leak test tank, see procedure page 3.
Insulation Level Withstand Tests
High-potential withstand tests provide information on the dielectric condition of the interrupter. Testing is performed at
75% of the rated low-frequency withstand voltage.

TEST RESULTS: These high potential withstand tests provide
information on the dielectric condition and integrity of the interrupters.
A. If the interrupter passes the closed-contacts test (Tests 1
and 2) but fails the open-contacts test (Test 3),a deterioration of one or more of the interrupters is likely to be the
cause. Check each interrupter individually to determine the
failed phase or phases, and replace the interrupter(s).
Retest to confirm the repair.
B. If the interrupter fails the closed-contacts tests (Test 1 and
2) the cause is likely to be failed insulation. Replace damaged interrupter and retest.
SHOP MAINTENANCE PROCEDURES
Leak Testing Tank
If the interrupter is installed in an environment where it may be
submerged, it should be leak tested after the tank has been
removed and replaced, to ensure that all seals are fluid tight.
*May be limited by cables or terminations.
CAUTION
WARNING
Proper cable terminators must be used to attach test supply to the interrupter bushing terminals. Use of improper
cable terminators can result in flashovers, damage to
equipment, serious personal injury or death.
TEST 1: Proceed as follows:
1. Manually close interrupter.
2. Ground tank and frame.
3. Connect three upper bushings together.
4. Apply proper test voltage to lower bushings.
5. The interrupter should withstand the test voltage for 60
seconds.
TEST 2: Proceed as follows:
1. Manually close interrupter.
2. Ground tank and frame.
3. Ground Phase A and Phase C.
4. Apply proper test voltage to Phase B.
5. The interrupter should withstand the test voltage for 60
seconds.
TEST 3: Proceed as follows:
1. Manually open interrupter.
Do not pressurize tank assembly to more than 5 psi. Pressures
beyond 5 psi can cause permanent damage to the tank assembly and seals.

Interrupter Replacement
The vacuum interrupters used in the Type Cl interrupter are of
an encapsulated design. If the interrupter or interrupter housing are damaged in any way the entire assembly must be
replaced. To replace an interrupter assembly proceed as follows, refer to Figure 9 for item references:
6
Rotating the body of the aperseal may break the seal between
body and cable. This will provide a path for moisture, or other
contaminants, to enter the interrupter operating mechanism
tank. This will damage the mechanism and may render it inoperative.
To remove or install an aperseal secure the aperseal body with
soft-jawed pliers (to prevent it from rotating), while turning the
nut. When tightening—tighten to 45-55 inch-pounds torque.
Electronic Trip Control
The electronic trip control monitors the current level passing
through the Cl interrupter, by measuring the voltages produced in
the bushing mounted current transformers. If excessive current
levels are present, the control initiates a trip signal.
Repairs to the control are limited to the replacement of damaged components, ie. control circuit board, switches or diodes.

TESTING CT PROTECTION BOARD
The CT protection board provides automatic protection for the
bushing mounted CTs. It is located within the mechanism tank,
on the left side of the mechanism frame. When the control is
removed from an in-service interrupter, the CT protection
board will automatically protect the CTs. If the CT protection
board malfunctions, CT(s) can be damaged. The following
tests can be used to verify that the protection board is working
properly.
Test circuits for the CT protection board are shown in
Figures 10 and 11. The board can be tested without removal
of either the mechanism tank or it may also be bench tested.
Test Procedure
TESTING IN PLACE
Assemble and connect the equipment as shown in Figure 10,
which shows the test current being applied to phase A.
1. Manually close the interrupted contacts, refer to manual
closing procedure.
2. Slowly increase the voltage on the variable transformer
while observing the voltage between pins A and D.
3. After approximately 115 volts, the voltage should drop off
even though the voltage from the variable transformer is
increased. If the voltage does not drop off, the CT protection board is not operating properly and must be replaced.
4. Disconnect input power and reconnect to test phase B and
then phase C. Ground can be tested between pins E & F
while the test circuit is connected to any phase.
BENCH TESTING
Assemble and connect the equipment as shown in Figure 11,
which shows the test voltage being applied to phase A.
1. Slowly increase the voltage on the variable transformer
while observing the voltage between the 1000:1 CT leads.
2. After approximately 115 volts, the voltage should drop off
8
even though the voltage from the variable transformer is
increased. If the voltage does not drop off, the CT protection
board is damaged and must be replaced.
3. Disconnect input power and reconnect to test phase B,
phase C and ground.
OPERATING PROCEDURES
The interrupter should not be operated or placed into service
until there is a full understanding of its operating procedures.
Mechanism and control levers and indicators referred to in this
section are identified in Figures 12 and 13.
Mechanical Operation Check
A simple nonelectric test of interrupter operation will assure that
the operator mechanism and the interrupter linkage are functioning properly. The following procedure may be used.
1. Remove control fuse from 120 volt ac fuse block in cabinet
interior to isolate mechanism from electrical system.
2. Check that the interrupter is open. The Contact-Position
Indicator visible from the front of the mechanism tank should
read OPEN.
NOTE: If interrupter is closed move the Trip-Reset handle at the
front of the mechanism tank to TRIP. This will release a latch in the
mechanism and open the interrupter contacts. The Contact-Position
Indicator will then read OPEN.
3. Using the manual closing procedure described in Manual
Closing section, close the interrupter. The Contact-Position
Indicator should read CLOSED.
4. Move the Trip-Reset handle to TRIP. The interrupter contacts
should open and the Contact-Position Indicators should read
OPEN.
Successful completion of the above four steps confirm proper operation of the interrupter operating mechanism.

Electrical Operation Check
The following procedure may be used to check the electrical
operation of the interrupter.
1. Make sure that the Trip-Reset handle on the mechanism
tank is set on RESET.
2. Apply 120 volt ac power. Upon application of power, the
spring-charging motor will run to charge the closing
springs. The spring-charging motor will stop running when
the springs are fully charged and the spring indicator will
indicate that the springs are charged.
3. To close the interrupter, move Manual Control switch on
control panel to CLOSE. The interrupter should close
immediately. The red indicator lamp on the control panel
should light and the Contact-Position Indicator at the front
of the mechanism tank should read CLOSED.
4. To open the interrupter, move the Manual Control switch to
TRIP. The interrupter should open. The green indicator
lamp on the control panel should light and the ContactPosition Indicator in the mechanism tank should read
OPEN.
Manual Closing
Manual deenergized closing into an energized line,without the
120 volt ac supply, can be accomplished with the Push-Pull
handle located on the left front of the mechanism tank (Figure
12).
1. If the electronic control is connected, make sure the manual
control switch on the control panel has been moved to the
TRIP position and released.
2. Move Trip-Reset handle, right front of mechanism tank to
either the TRIP or RESET position.
3. Pull Push-Pull handle approximately 30 times, or until the
operating spring indicator reads SPRING CHARGED.
4. Move Trip-Reset handle to CLOSE. Interrupter contacts will
close and handle will spring back to the RESET position.
Manual Tripping
A closed interrupter can be manually tripped at the operator
mechanism by moving the Trip-Reset handle at the front of the
tank to TRIP.
This will release a trip latch in the operating mechanism,
allowing the charged opening springs to drive the contacts to
their open position.
The interrupter cannot be closed while the Trip-Reset handle is in the TRIP position.
10
IN-SERVICE OPERATION
Initial Operation
To place the interrupter in operation, proceed as follows:
1. Make sure that the control cables extending from the interrupter are connected to the control and that 120 volt ac power
is supplied to the control.
2. Make sure that the Trip-Reset handle at the front of the interrupter mechanism tank is in the RESET position.
3. Move the Manual Control switch on the electronic control
panel to CLOSE. The interrupter will close. The red indicator
lamp on the control panel will light and the indicator flag in the
mechanism will read CLOSED.
Automatic operation
Once the unit is closed and in service, the electronic control will
automatically trip the interrupter in accordance with the programmed operating characteristics when a phase or ground fault
occurs. While closed, the red indicator lamp on the control panel
will provide a continuous indication of closed contacts. The indicator flag, visible through a viewing port at the front of the mechanism tank, will display CLOSED.
To open the interrupter while it is in service, move the manual
control switch to TRIP. The interrupter will immediately open.
Whether tripped automatically or manually, the green indicator
lamp on the panel and the OPEN position of the mechanism flag
will indicate open contacts.
If the remote control operating feature is being used, operations initiated by the remote trip and close dry contacts will be
identical to those initiated with the Manual Control switch.
Indicator lamp and Contact-Position Indicator displays will also
be the same.
