PRODUCT INFORMATION
Introduction
Operation
Service Information S280-40-7 provides Maintenance
instructions for Types RXE and WE three-phase, electronically controlled, oil interrupted reclosers. Included is
a general description of the recloser and its operation,
instructions for periodic inspection and routine maintenance, testing procedures, and instructions for shop
repairs. A service parts list, keyed to exploded-view drawings of the recloser is included at the back of the
manual.
The Type RXE and WE reclosers trip open an overcurrent (either phase or ground faults) and then reclose
automatically. If the overcurrent is temporary the automatic recloser restores normal service. If the fault is permanent a preset number of trip and reclose operations
are performed to lockout. All three phases of the RXE
and WE reclosers open, reclose and lockout simultaneously.
Refer to the specific electronic recloser control service
information for control checking, testing, and troubleshooting procedures.
Read This Manual First
Read and understand the contents of this manual and follow all locally approved procedures and safety practices
before installing or operating this equipment.
Additional Information
These instructions cannot cover all details or variations in
the equipment, procedures, or process described, nor
provide directions 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, contact your
Cooper Power Systems sales representative.
IEEE Standards
Kyle type RXE and WE reclosers are designed and tested in accordance with IEEE standards C37.60-1981™
and C37.61-1973™.
Quality Standards
The Quality System at the Cooper Power Systems Kyle
Distribution Switchgear plant is certified to the ISO 9001
standard.
Handling and Storage
Be careful during handling and storage of the control to
minimize the possibility of damage. If the recloser is to
be stored for any length of time prior to installation, provide a clean, dry storage area.
Opening sequences can be all fast, all delayed, or any
combination of fast operations followed by delayed operations up to a total of four. Fast operations clear temporary faults before branch-line fuses can be damaged.
Delayed operations allow time for fuses or other downline
protective devices to clear so that permanent fauIts can
be confined to smaller sections of Iine.
Fast arc interruption is provided by bridge-type contacts
which provide two breaks in series per phase. Each current break has a self-generating type arc interrupting
structure with a series of vented chambers. As the contacts open, the arc generates gas pressure within the
structure chamber which blasts oil across the arc and out
through the vents. The moving-bridge type contacts are
driven by the release of opening springs that are loaded
when the recloser mechanism is closed.
Closing energy, as well as energy to charge the opening
springs, is supplied by a high-voltage closing solenoid
momentariIy connected phase-to-phase through a highvoltage contactor. The contactor is mechanically closed
by a rotary solenoid actuated by a signal from the electronic control.
A trip-free, yellow operating handle located under the
sleet hood will manually lock open the recloser. It cannot
manually close the recloser but must be in the CLOSED
position for the rotary close solenoid to operate. A red
contact position indicator linked to the recloser mechanism, but independent of the operating handle, is also
located under the sleet hood.
The location of the major operation components of the
RXE recloser is shown in Figure 2. They are similar for
the WE recloser. Being aware of the location of these
components and their part in the operation of the recloser will give a quicker and clearer understanding of the
recloser maintenance and repair procedures that follow.
Description
The Type RXE and WE reclosers are self-controlled
devices that protect distribution lines and equipment. A
complete unit consists of the recloser, an electronic control, and an interconnecting cable. Fault current sensing
is provided by the control which actuates the recloser.
Circuit interruption is provided by the recloser.

Mechanism Operation
The head mechanism performs the actual opening and
closing operations in response to signals from the electronic control. Contact opening is initiated by a trip coil.
Contact closing is performed by the closing coil, mounted below the mechanism. The basic operation of lever
arrangement is shown in Figure 3.
With the contacts closed (a) the opening springs are fully
extended. The trip coil push rod rests up against the toggle latch and when the trip coil is energized, the toggle
opens (b). The contact-and-toggle-support assembly and
the contact-and-trip arm assembly rotate on their shafts
and begin to push the contacts open. As the opening
springs rotate the contact-and-trip-arm assembly past
this point (c), the trip arm moves the reset trip lever,
which releases the reset lever. The reset lever is rotated
by a spring and snaps the toggle closed. This motion of
the reset lever also pulls the plunger out of the closing
coil. At this point the contacts are completely open.
The closing coil is energized by a signal to the rotary
solenoid on the side of the mechanism. The solenoid
closes the closing solenoid contactor, which energizes
the coil. The plunger is drawn into the coil and the reset
lever is pulled back (d) to its original position, at the same
time closing the contacts. The mechanism is then ready
for another cycle.

MAINTENANCE
Frequency of Recloser
Maintenance
Because reclosers are used under widely varying operating and climatic conditions, maintenance intervals are
best determined by the user, based on actual operating
experience. To assure proper and trouble-free operation,
reclosers must be maintained when they have operated
the equivalent of a rated duty cycle, refer to Table 3. In
the absence of specific operating experience, the following procedures are recommended:
A. When RXE or WE reclosers are operated under
usual service conditions as defined in ANSI standard
C37.60, “Standard Requirements for Overhead, Pad
Mounted, Dry Vault and Submersible Automatic
Reclosers and Fault Interrupters for AC Systems”, it
is recommended that the following maintenance procedures be performed at the completion of an equivalent duty cycle.
NOTE: ANSI C37.61, “Guide for the Application, operation
and Maintenance of Automatic Circuit Reclosers”
gives a procedure for converting the standard duty
cycle, as shown on page 6 of these instructions into
an equivalent duty cycle based on the actual operating duty of the recloser.
B. If the recloser has not completed an equivalent duty
cycle within three years, it is recommended that an
inspection be made at that time. See Periodic
Recloser Inspection and Maintenance.
Periodic Recloser Inspection
and Maintenance
Each periodic inspection should include the following steps:
WARNING: Hazardous Voltage. This equipment
must be de-energized and grounded prior to conducting any maintenance, oil sampling, or oil filling procedures. Failure to comply can result in death or severe
T239.1
personal injury.
!
1. Bypass and remove recloser from service using all
locally approved safety practices. Carefully transport
the unit to a suitable service facility.
CAUTION: Equipment damage. Keep work
areas clean to prevent debris from accumulating
on or in the hydraulic mechanism during disassembly
and reassembly of components. Failure to comply can
result in hydraulic failure and recloser misoperation. T254.0
!
2. Inspect external components.
A. Check for broken or cracked bushings and replace
as necessary. Refer to Bushings section of this
manual.
B. Check for paint scratches and other mechanical
damage. Paint to inhibit corrosion.
C. Record counter reading from control in recloser
record log.
WARNING: Hazardous Voltage. The switchgear
and high voltage transformer must be in a test
cage or similar protective device to prevent accidental
contact with the high voltage parts. Solidly ground all
equipment. Failure to comply can result in death,
severe personal injury, and equipment damage. T221.3
!
3. Perform a dielectric withstand test to check the insulation level of the recloser and the dielectric integrity
of the interrupter assemblies. Refer to Insulation
Level Withstand Tests section of this manual.
CAUTION: Equipment damage. Recloser must be
open (yellow operating handle, under sleethood, down)
before untanking. Tripping the mechanism out of oil will
cause excessive mechanical shock to the operating
mechanism, which will cause accelerated wear and/or
damage to the mechanism.
T202.0
4. Untank the recloser to expose the internal components.
CAUTION: Dielectric failure, equipment damage. Never use volatile solutions, detergents, or
water-soluble cleaners when cleaning the interior of
this equipment. These cleaners will contaminate the
insulating oil, reducing its dielectric strength. Operation
with contaminated insulating oil can result in internal
flashovers that will cause equipment damage and possible personal injury.
T201.2
!
5. Clean all internal components.
A. Remove all traces of carbon by wiping with a
clean, lint-free cloth.
Note:
Although current interruption takes place in a
sealed vacuum chamber, the closing solenoid
contactor operates in oil and will produce some
carbon deposits.
B. Flush the mechanism with clean, dry insulating oil.
6. Remove the moving contact assembly from the bottom of the contact lift rod to check the erosion of the
contacts.
Arcing tips of the moving contacts can experience
considerable erosion before replacement is necessary. Slight pitting and discoloration can be dressed
with a piece of crocus cloth. However, erosion of the
load current carrying contact surfaces requires
replacement of the entire internal structure before its
effectiveness is impaired. Figure 4 shows a set of
moving contacts after they have experienced severe
interrupting duty and a new set for comparison. The
used contacts have reached the condition where they
should be replaced.
7
Types RXE and WE Electronically Controlled Recloser Maintenance Instructions
If dielectric strength is less than 22 kV rms, it must be
replaced:
A. Drain the tank, and clean out all sludge and carbon deposits.
B. Fill with new, clean insulating oil up to 2-1/4 inches below the top of the tank flange.
NOTE:Tank capacity is approximately 41 U.S. gallons.
Refer to Oil Condition section of this manual.
9. Clean and examine the head gasket. Replace if it is
cracked, cut, or otherwise damaged, or if it has been
permanently deformed.
10. Clean the head gasket seat and retank the recloser.
Figure 4.
Left: contact assembly new; right: moving contact
assembly after one full duty cycle
7. Check circuit components attached to the recloser
head, frame and operating mechanism.
A. Check condition of the wiring to the terminal strip
and make sure all connections are tight.
B. Make sure that the rotary solenoid and the trip
solenoid are firmly attached to the recloser frame.
C. Check SW1, SW2, and SW3 switches as applicable:
WARNING: Hazardous material. Do not open
mercury switches or come in direct contact with
switches exhibiting any sign of mercury leakage.
Exposure to mercury can cause serious health problems.
T281.0
!
• For units with two mercury switches and one
microswitch:
1. Check that the two mercury switches (SW2 and
SW3) are securely held in place by the nylon
mounting straps.
Note:
Mercury Switch-to-Microswitch Retrofit Kit
KA349WE is available to replace existing
mercury switches with microswitches.
Contact your Cooper Power Systems representative for additional information.
2. Check condition of microswitch (SW1)
mounted above main shaft.
• For units with three microswitches: Check condition of all three microswitches.
D. Check condition of the bushing current transformers and the associated wiring.
E. Check the control cable receptacle (Figure 2). If
circuit component malfunction is suspected, refer
to Operational Checks section of this manual.
8. Check the dielectric strength of the insulating oil. An
oil sample taken near the bottom of the tank should
have a dielectric strength of not less than 22 kV rms.
8
A. Move the yellow operating handle to the up position to avoid any possible binding while retanking.
B. Replace the head bolts and tighten to 35-55 ft-lbs.
torque. Apply clamping force gradually and equally, in rotation, to each bolt to achieve an evenly
distributed gasket sealing pressure.
NOTE: Type WE reclosers serial 800 through 6049 and
RXE below serial 345 require the following special thread-sealing procedure to keep moisture
from entering the tank along the threads of the
head bolts.
1. Before reinstalling the head bolts, apply a liberal amount of a non-hardening pliable
sealant, Permatex® Form-A-Gasket® No. 2, to
the end of each bolt. The four leading threads
should be completely coated.
2. When the bolt is installed, a slight bead of
material (resembling an o-ring) should
remain on the top of the tank flange. Apply
the sealant each time the head bolts are
removed and reinstalled.
11. Check the oil level with the dipstick in the head and
adjust the level to the upper line on the dipstick.
NOTE: If the recloser is equipped with an oil-sight gage, the
oil level should be above the sight gage. If the oil
surface line is visible in the window, add oil to raise
the level to the upper line on the dipstick.
11. Perform a dielectric withstand test to check the insulation level of the recloser and the vacuum integrity of
the interrupters. Refer to Insulation Level Withstand
Tests section of this manual.

Withstand Test Results
These high potential withstand tests provide information
on the dielectric condition of the recloser and the integrity of the interrupters.
If the recloser passes the closed-contacts tests (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.
If the recloser fails the closed-contacts tests (Test 1 and
2) the cause is likely to be a diminished electrical clearances, low oil dielectric strength or failed insulation. After
correcting the problem, retest to confirm the repair.
Oil Condition
Oil provides the internal insulation barrier between phases and from phase to ground, and must be replaced
before it deteriorates below a safe dielectric level.
Replace the oil if its dielectric strength falls below 22 kV.
New oil should always be filtered before using even though
it is obtained from an approved source. Passing the oil
through a blotter press will remove free water and solid
contaminants such as rust, dirt, and lint. Keep aeration to a
minimum during filtering to prevent moisture in the air from
condensing in the oil and lowering its dielectric strength.
Used oil must be treated before reusing. Filtering may
remove absorbed and free water and other contaminants
to raise the dielectric strength to acceptable levels.
However, filtering does not always remove water-absorbing contaminants and the dielectric strength may fall
rapidly after being returned to service. Therefore the
recloser should be filled with new oil, or oil that has been
restored to like-new condition. Oil used in these reclosers
conforms to ASTM Standard D3487, Type l; its property
limits are shown in Table 4.
ADJUSTMENTS
Control
Refer to the control installation manual for applicable procedures for adjusting operations to lockout, reclosing time,
phase-trip sequence, minimum-trip values, resetting time,
ground-trip sequence, phase-trip timing and ground-trip
timing.
Control Lever Overtravel Adjustment
Check for proper adjustment of the control lever by first
removing the sleet hood cover to expose the control lever.
From the OPEN position, slowly push the control lever
toward the CLOSED position. As the lever is pushed up,
latching of the recloser will be felt. At this point the dimension between the top of the control lever and the underside
of the sleet hood should be 1/4 inch (Figure 9).
If the control lever is not adjusted properly, remove the Cring and slide the control lever from the shaft. Rotate the
control lever clockwise to reduce the dimension or counterclockwise to increase the dimension. Slide the control
lever back onto the shaft and recheck the dimension.
When the proper dimension has been obtained replace the
C-ring.

PROCEDURES
5. Twist off the split aluminum clamping ring from the old
bushing and install on the new bushing if it is in good
condition; replace the ring if damaged.
WARNING: Hazardous Voltage. This equipment must be de-energized and grounded prior
to conducting any maintenance, oil sampling, or oil filling procedures. Failure to comply can result in death or
severe personal injury.
T239.1
CAUTION: Bushing damage. The split aluminum ring
must be replaced if damaged. The clamping ring cushions and distributes the pressure between the bushing
flange and the bushing. If bushing clamps are assembled without a new clamping ring, the bushing may be
damaged when clamp hardware is tightened.
T234.1
!
CAUTION: Equipment damage. Keep work
areas clean to prevent debris from accumulating
on or in the hydraulic mechanism during disassembly
and reassembly of components. Failure to comply can
result in hydraulic failure and recloser misoperation. T254.0
!
The operations described in this section should be performed under the cleanest conditions possible. The repair
work (except for bushing replacement), will be simplified if
the workbench is arranged so the mechanism/head
assembly can be inverted (bushings down). No special
tools are required for any of the repair procedures.
Bushings
Bushing maintenance generally consists of a thorough
cleaning and a careful examination for chips, cracks or
other mechanical damage during the periodic maintenance inspection. Bushings must be replaced whenever
damage is discovered. Refer to Figure 10 and proceed
as follows:
1. Bypass and remove recloser from service using all
locally approved safety practices.
2. Carefully transport the unit to a suitable service facility.
6. Install the bushing assembly (new or reworked) into
the head using a new lower bushing gasket. Position
the bushing with the stud end of the terminal pointing
outward.
7. Position the clamping ring with the split centered
between two clamping bolts.
CAUTION: Dielectric failure, bushing damage.
To prevent gasket leaks or bushing damage,
clamping force must be applied gradually and equally
in rotation to each bolt. If the clamping force is not
evenly applied, seal leakage can result, compromising
the dielectric capabilities of the recloser and can cause
possible personal injury. Unequal clamping force can
cause bushing breakage.
T235.2
!
8. Reassemble the bushing to the head casting. Tighten
the bolts evenly, a little at a time, to a torque of
10-15 ft-lbs.
NOTE: Clamping forces must be applied gradually and
equally in rotation to each bolt. This results in an
evenly distributed gasket sealing pressure
9. Reconnect the lead to the bushing rod.
3. Disconnect the bushing lead from the bottom end of
the bushing rod.
4. Remove the three hex-head cap screws and clamps
that secure the bushing to the head and lift out the
complete bushing assembly.
5. Remove and discard the lower bushing gasket.
6. Depending upon the extent of damage, the complete
bushing assembly can be replaced or new ceramic
only can be installed. If new ceramic only is to be
installed, refer to Figure 11 and proceed as follows:
A. Unscrew the bushing terminal and withdraw the
rod from the bottom of the bushing ceramic; discard the terminal gasket.
B. Insert the rod assembly all the way into the new
ceramic, making sure the roll pin is seated in the
locking groove in the top of the bushing.
C. Assemble the terminal to the bushing rod using a
new terminal gasket; tighten to 35 ft-lbs. of torque.
NOTE: Apply a very small amount of petroleum jelly to
the knurled surface of the inside face of the terminal before assembly to the bushing rod.

Operational Checks
An internal connection diagram of the recloser circuits is
shown in Figure 27. The operating sequence for the various circuit components is diagrammed in Figure 28.
These components should provide trouble-free operation
with little or no maintenance. However, if the recloser
does not operate properly, the following checks can be
made to trouble-shoot the recloser circuits.
Refer to the specific electronic recloser control service
information for control checking, testing, and troubleshooting procedures.
The recloser need not be untanked to perform these
checks.
CONTROL CABLE
Using an ohmmeter, check the continuity between like
pins and pin sockets of the connector plugs on either end
of the electronic control cable and for discontinuity
between unlike pins and pin sockets to determine the
condition of the control cable.
NOTE: Pins or pin sockets N and P on either plug are not
connected.
Repair or replace the control cable if defective.
CIRCUIT COMPONENTS
(read the effective dc resistance of the closing coil)
confirming that the closing solenoid contactor is

All measurements are made at the pin sockets of the
control cable receptacle on the recloser head. A reading
within + 15 percent of the specified value indicates components are operational. Any component failing to meet
the specified checks should be replaced. Figure 29 identifies the various circuit components.
The current sensing transformers are mounted on the
source side bushings underneath the head casting. The
battery charger CT power source (if applicable) is mounted on the load side center bushing.
NOTE: If the electronic control battery is used to supply the
25 vdc power, connect as directed for only as long
as necessary to perform the specified action to prevent excessive battery drain.
1. Connect an ohmmeter, in turn, to pin sockets K and
G, K and H, and K and J to check the continuity of the
three current sensing transformers. The meter should
read approximately 7 ohms, the dc resistance of each
winding.
Trip-Solenoid
1. Connect an ohmmeter between pin sockets A and B.
The meter should read approximately 9.5 ohms.
2. Lift up the yellow manual operating handle under the
sleet hood and manually close the recloser with the
T-handle closing tool as described on page 9.
3. Momentarily apply 25 vdc to pin sockets A (+) and
B (+). The recloser should trip.
Rotary Solenoid and Closing Solenoid Contactor
1. Connect an ohmmeter between pin sockets E and F.
The meter should read approximately 19 ohms.
2. With the yellow manual operating handle in the up
position and the recloser contacts open, momentarily
apply 25 vdc to pin sockets F (+) and E (-). The rotary
solenoid should operate producing an easily distinguishable sound. Repeat two or three times.
3. Connect the ohmmeter across source side B and C
phase bushings, or from source side C bushing to
recloser ground (depending upon the recloser coil
connection) and again energize the rotary solenoid.
The meter should indicate closing coil continuity
20
Continuity Check
2. Connect the ohmmeter to pin sockets K and L to
check the continuity of the battery charger CT winding, if used. The meter should read approximately
1000 ohms. A zero ohms reading indicates the 0.2
mfd capacitor may be short-circuited. Readings deviating more than ± 20% from 1000 ohms indicates a
damaged resistor or transformer winding.
Ratio Test for Sensing CT's
1. Connect all three phases of the recloser in series as
shown in Figure 30 and close the recloser contacts
with the manual closing tool.
2. Connect a 100 ampere ac test current to test points 1
and 2.
3. Energize the 100 ampere test source.
4. Using a multimeter on the 0-500 milliamp range,
check the current output across socket pins K-G, K-H,
and K-J (Figure 30A). The output of each CT should
measure 100 ma + 10%.
NOTE: Be sure to allow for the tolerances of meter being
used. The resistance of certain type of meters is not
negligible. Use as high a scale (lower resistance) as
is accurately readable.

2. Energize the 100 ampere ac test source.
A. All three transformers should have the same
polarity; the output should measure 300 ma.
B. If one transformer has its polarity opposite of the
remaining two the output will measure 100 ma.
3. De-energize the test source and remove the jumper
wire from the receptacle.
NOTE: Ratio and polarity test-circuits shown are the effective circuits that contribute to the testing.
Components not having an effect on the current
flow are not shown. Dotted lines in the polarity-test
circuit are test leads.
Output Test of Battery Charging CT, if Used
1. With the phases still connected in series, energize
100 ampere ac source.
2. Measure the output between pin socket K and L of the
control cable receptacle. The output should measure
40-60 ma.
3. Readings within this range indicate sufficient output
to maintain control battery charge.
