TYPE R THREE-PHASE RECLOSER MAINTENANCE INSTRUCTIONS MN280026EN November 2015
Product information
Introduction
Service Information MN280026EN provides maintenance
instructions for Eaton’s Cooper Power™ series Type R threephase recloser serialed 3733 and above or beginning with
CP57. A service parts list is included.
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.
Opening sequences of the recloser can be all fast, all
delayed, or a combination of fast and delayed. When the
combination sequence is used, fast operations always
precede delayed operations. On coordinated systems,
fast recloser operations are used to clear temporary faults
before branch-line fuses are damaged. Subsequent timedelayed openings allow fault currents to flow long enough to
be cleared by branch-line fuses. Therefore, outages caused
by permanent faults are confined to shorter sections of line.
The basic recloser functions described above can be
modified by one or more accessory devices designed
for the Type R. For complete information about these
accessories, refer to the recloser installation manual and the
bulletin covering recloser accessories.
Component functions
Additional information
These instructions cannot cover all details or variations in
the equipment, procedures, or process described nor to
provide directions for meeting every possible contingency
during installation, operation, or maintenance. For additional
information, contact your Eaton representative.
Acceptance and initial inspection
This product is completely assembled, tested, and
inspected at the factory. It is carefully calibrated, adjusted,
and in good condition when accepted by the carrier for
shipment.
Upon receipt, inspect the carton for signs of damage.
Unpack the control and inspect it thoroughly for damage
incurred during shipment. If damage is discovered, file a
claim with the carrier immediately.
Arc-interrupting structure
Included in the Type R recloser is a heavy-duty cross-blast
arc-interrupting structure for each phase. Circuit opening
is provided by the double moving contact assembly. When
fault current is interrupted, gas pressure—developed by the
arc in the interrupting chamber—blasts clean cool oil across
the arc in the exhaust chamber. Through this action the arc
stream is cooled and elongated and dielectric strength is
re-established between the open contacts.
Closing solenoid
Moving contacts are closed by the closing solenoid
which also extends the opening springs located in the
head assembly. This solenoid is energized only a few
cycles during each closing operation when it is connected
momentarily across two source phases.
Handling and storage
Be careful during handling and storage of this equipment to
minimize the possibility of damage. If the recloser is to be
stored for any length of time, provide a clean, dry storage area.
Standards
Eaton’s reclosers are designed and tested in accordance with
ANSI® standards C37.60 and C37.85 and ANSI® guideline
C37.61.
Snap-action contacts complete a circuit to the closing
solenoid for each closing operation.
Fuse
Overvoltage protection of the system is provided by two
closing solenoid fuses.
Hydraulic pump and lockout piston
Quality standards
ISO 9001 certified quality management system
Description
Closing-solenoid contactor
The Type R recloser is a self-contained device that senses
single- or three-phase fault currents and simultaneously
interrupts all three phases of a distribution circuit. If the fault
is temporary, the recloser automatically recloses to restore
service and then resets for another cycle of operations.
If the fault is permanent, the recloser locks open after
one, two, three, or four operations, depending upon its
predetermined adjustment.
Each time the recloser trips, the hydraulic pump makes
one stroke, forcing a measured amount of fluid under the
lockout piston. This causes the lockout piston to advance a
definite amount during each recloser trip operation. In turn,
the lockout piston advances a lockout bar. After the selected
number of fast operations, the lockout bar causes the
series-trip solenoid plunger linkage to engage the time-delay
units. When the selected number of trip operations has
occurred, the lockout bar prevents reclosing and locks out
the recloser.

TYPE R THREE-PHASE RECLOSER MAINTENANCE INSTRUCTIONS MN280026EN November 2015
Location of maintenance
Series-trip solenoid
This device in each phase carries full line current. When
current greater then the minimum trip value flows, the
solenoid plunger moves downward, causing a recloser trip
operation. The plunger is restrained by time-delay units
when delayed openings are called for and therefore requires
more time to trip the recloser.
Time-delay
A sealed time-delay unit for each phase provides consistent
delay action by forcing hydraulic fluid through an orifice. In
order to ensure reliable timing characteristics, fluid used in
the time-delay units is HFA (Hydraulic Fluid, Aircraft) and not
switchgear oil.
Routine inspection, minor maintenance, most adjustments,
and replacement of oil can be performed on a recloser
without removing it from the mounting frame. Repairs or
major maintenance work should be performed in the shop.
Table 1. NEMA® Standard Duty Cycle for Power Class II
Reclosers
Percent of
Interrupting Rating
Reclosers are applied widely to increase service continuity,
reduce system operating costs, and increase revenue. The
Type R performs these recloser functions, and also meets
requirements for many new applications made possible by
the Type R’s two-cycle clearing time and 100 mVA maximum
interrupting capacity. However, the Type R can perform at
peak efficiency only if it is maintained in good condition.
While maintenance is relatively easy and inexpensive, it is
important.
Oil condition
Oil plays an important role in several recloser functions.
It is essential in arc interruption, insulation, counting, and
reclosing. However, because arc interruption contributes to
oil decomposition, the oil steadily diminishes in dielectric
strength as the recloser continues to clear fault currents.
Breathing action may result in moisture absorption by the
oil, thus lowering its insulation value. For effective recloser
operation, oil must be replaced before it deteriorates
beyond a safe level.
Maintenance intervals
Frequency of maintenance depends upon local climatic
conditions and the interrupting duty imposed on the
recloser. It is recommended that the unit be completely
inspected, cleaned, and filled with new oil at least once
each year. If the Type R operates through a duty cycle
in less than one year, periodic maintenance should be
per-formed then. Refer to Table 1 for the NEMA® standard
duty cycle for Power Class ll reclosers.

Field inspection and maintenance
WARNING
Hazardous voltage. The switchgear (apparatus and
control) and high-voltage transformer must be in a test
cage or similar protected area to prevent accidental contact with the high-voltage parts.
WARNING
Do not operate this equipment if energized parts are not
immersed in dielectric fluid. Operation when parts are
not properly immersed in dielectric fluid may result in
internal flashovers that will damage the equipment and
can cause death or severe personal injury.
G104.4
Solidly ground all equipment. Failure to comply can
result in death, severe personal injury, and equipment
damage.
T221.5
WARNING
Hazardous voltage. This equipment must be de-energized and grounded prior to conducting any maintenance, dielectric fluid sampling, or dielectric fluid filling
procedures. Failure to comply can result in death or
severe personal injury.
T239.2
WARNING
Do not rely on the open position of the yellow operating handle or the contact position indicator; it does
not ensure that the line has been de-energized. Always
establish a visible disconnect. Failure to follow proper
safety practices can result in contact with high voltage,
which will cause death or severe personal injury.
G114.1
CAUTION
Equipment damage. Recloser must be open (yellow
operating handle, under sleet hood, 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
CAUTION
Equipment damage. Keep work areas clean to prevent
debris from accumulating on or in the hydraulic mechanism during disassembly and reassembly procedures.
Failure to comply can result in hydraulic failure and
recloser misoperation.
T254.0
Figure 2. Moving contact assembly, after severe duty, is
shown behind new assembly example.
4. Inspect moving contacts. Arcing tips of the moving
contacts can experience considerable erosion before
replacement is necessary. The contacts should be
replaced before their effectiveness is impaired by
erosion of the load current contact surfaces.
NNote: Figure 2 shows a set of moving contacts after one
duty cycle, compared to a new set. The used contact
and yoke assembly should be replaced as described
in the Arc-Interrupting Assembly section for the
appropriate serial number.
5. Inspect exhaust chamber orifices. Each time a fault
or load current is interrupted by the recloser, the
twelve holes in each exhaust port (Figure 3) will
experience some erosion. If any of these holes become
enlarged to 9/64-inch diameter, the exhaust structure
should be replaced. A convenient gage is a 9/64-inch
drill. Disassembly instructions are contained in the
Arc-Interrupting Assembly section of this manual.
CAUTION
Falling equipment. Use the lifting lugs provided and follow all locally approved safety practices when lifting and
mounting the equipment. Lift the unit smoothly and do not
allow the unit to shift. Improper lifting can result in severe
personal injury, death, and/or equipment damage.
G106.3
1. Bypass, trip, and de-energize the recloser.
2. Inspect external components. Check for broken
bushings, paint scratches, or other mechanical damage.
3. Lower the tank to expose internal components. Attach
sheaves of the tank hoisting mechanism to the recloser
tank and take up slack. Then remove the ten head bolts
to free the tank from the head casting.
4
Figure 3. Exhaust port orifice.
6. Inspect stationary contacts. If replacement of the
exhaust chamber or moving contacts is indicated,
also inspect the stationary contacts. This inspection
can be omitted if the exhaust chamber and moving
contacts appear to have further useful life. Stationary
contacts are designed to last at least as long as moving
contacts.
TYPE R THREE-PHASE RECLOSER MAINTENANCE INSTRUCTIONS MN280026EN November 2015
Both contact shoes of each stationary contact assembly
can be changed without replacing the fiber parts of
the arc-interrupting structure. It is recommended,
however, that both stationary contact tube assemblies
be replaced if arc erosion has spread to the load-current
transfer surfaces of the stationary contacts.
NNote: Disassembly instructions for stationary contact
assemblies are contained in the Arc-Interrupting
Assembly section of this manual.
7. Clean all internal components and remove all carbon
traces by wiping with a clean, lint-free cloth. Pay
particular attention to all insulation members. Flush the
mechanism with clean, dry transformer oil.
CAUTION
This equipment relies on dielectric fluid to provide electrical insulation between components. The dielectric
strength of the fluid must be checked on a regular basis,
as part of the routine maintenance inspection, to ensure
that it is at or above minimum dielectric requirements.
Use of this equipment with dielectric fluid that does not
meet minimum requirements can result in internal flashovers that will damage the equipment and can cause
personal injury.
G107.3
8. Check fluid level in time delay units. A little loss of fluid
can be expected during normal operation. Check the
fluid in each of the three delay units as described in the
Time-Delay Units section of this manual. Add fluid as
needed.
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
9. Drain old oil by removing the 1/2-inch plug at the
bottom of the tank, or by opening the tank valve if one
has been installed. Rinse the tank with clean oil and
wipe out all carbon traces with a clean, lint-free cloth.
12. Clean the o-ring head gasket and the tank gasket seat.
Move the control lever to the closed position to avoid
any possible binding while raising the tank. Position the
tank so the special nameplate is on the same end as
the sleet hood and control levers. Raise the tank and
secure it to the head casting with the ten head bolts.
WARNING
Hazardous voltage. Never use a manual closing tool
to close an energized recloser. Manually closing an
energized recloser can result in contact with high voltage
that will cause death or severe personal injury.
T231.1
13. Check operation counter, control lever, contact position
indicator, and non-reclosing lever. Correct operation
of each of these components can be observed by
manually operating the recloser.
CAUTION
Do not turn the manual closing tool more than onequarter turn clockwise. Forcing the tool beyond the
mechanism stop may shear the pin on the closing shaft
of the recloser.
T222.0
CAUTION
Personal injury. Failure to maintain enough pressure to
hold down the closing shaft against the stop will cause
the opening springs to release and aggressively snap
the manual closing tool counter-clockwise resulting in
personal injury.
T283.0
14. Manually operate the recloser a few times after the
tank has been filled and secured in position to insure
that the dashpot and hydraulic pump are filled with oil.
Remove the closing tool port cover and gasket and insert
a KA90R closing tool. Manual operation can now be
achieved by closing with the KA90R tool and tripping the
recloser with the manual control lever. See Figure 4.
If a Type R recloser is to be operated out of oil, use the
closing tool to open the contacts. While one person turns
the tool clockwise against the stop, another can move the
trip lever, shown in Figure 5. Now let the tool slowly rotate
counterclockwise to open the contacts. Turn the tool 1/4
turn clockwise to close the contacts.
10. Inspect tank liners and replace any liners that appear
to have absorbed moisture. Any soft or spongy areas
in the liners indicate that moisture has been absorbed.
These areas are most likely to occur near the bottom of
the tank.
11. Fill recloser tank with oil using only new transformer oil
with dielectric strength of at least 26 kV, as measured
across a standard 0.1 inch gap in accordance with
methods illustrated in ASTM Publication D117. The oil
level should be 2-1/4 inches from the top of the tank
with the mechanism removed. Finally, the level must be
checked with the oil dipstick after the mechanisms and
head casting have been fastened in place. Add or drain
to level if necessary.

Shop maintenance
When shop maintenance or repairs are to be performed,
remove the ten bolts that secure the tank and head
castings. With a suitable hoist, raise the recloser
mechanism out of the oil and allow it to drain. During
maintenance, the recloser can be left suspended by the
hoist, or inverted and placed on a workbench.
Arc-interrupting assembly (units below serial no.
7701)
After the Type R recloser has performed a complete duty
cycle, each arc-interrupting assembly should be dismantled
completely and any worn parts replaced.

Series-trip solenoid (units below serial no. 9001)
Series-trip solenoids can be equipped with either standard
coils or an alternate coil. Standard coils, contained
completely within the solenoid frame, are used to achieve
tripping at approximately 200 percent of full-load rating.
Alternate 400X coil, with one-half turn outside the solenoid
frame, is used to achieve tripping at approximately 140
percent of full-load rating. The same basic procedure is used
to dismantle either solenoid.
Solenoid disassembly
1. Remove cotter pin, and slide out pin and spacer that
connect the insulated operating links, Figure 22, and
the solenoid plunger.

plunger. Next connect plunger to operating links.
Secure connecting bar and tighten the bolt on the other
end of the bar to complete reassembly.
NNote: Do not tighten screws that hold the guide clips.
These clips should be left free to move slightly.
However, reclosers now being produced have
bushings under the guide clip screws to prevent
over-tightening.
Series-trip solenoid (units above serial no. 9000)
Series-trip solenoids can be equipped with either standard
coils or an alternate coil. Standard coils are used to
achieve tripping at approximately 200 percent of full-load
rating. Alternate 400X coils are used to achieve tripping at
approximately 140 percent of fulload rating. The same basic
procedure is used to dismantle either solenoid.
Solenoid disassembly
1. Remove cotter pin and slide out the groove pin that
connects the insulated operating links and the solenoid
plunger (Figure 25).
2. Remove the terminal bolt that fastens both the bushing
lead and the outer coil terminal to the support bracket
(Figure 25).

strap and the fiber end of the support bracket to the
contact nut of the generator contact tube.
4. Remove the two frame mounting bolts that secure the
solenoid frame to the mounting board and lift the entire
solenoid assembly off the mounting board.
Figure 26. Solenoid disassembly.
Solenoid reassembly
Check upper coil washer before replacing coils. For coils
280 amperes and below, the upper and lower coil washers
are identical. For the 400 and 400X ampere coil a washer
with a larger center slot (1-17/32’’ long instead of 17/32”)
is substituted for the upper washer. The bottom washer
remains the same for all coils.
1. Place the lower insulation washer in position (Figure
27). Pass the upper insulation washer over the terminal
strap and position it on top of the coil in the position
shown in Figure 26. Push the coil into the solenoid
frame and slide the upper washer into its normal
position. Replace in order the guide channels, guide
clips, and plunger.
2. Place the solenoid assembly back on the mounting
board and secure it with the two frame mounting bolts.
3. Connect the operating links to the plunger with the
groove pin and replace the cotter pin.
4. A separate sleeve is provided with each coil to insulate
the outer coil terminal from the frame. Slide sleeve over
this outer coil (Figure 25).
Figure 27. Lower insulation washer.
Figure 25. Disassembly of series-trip solenoid. Above

5. Connect the terminals to the contact tube and the
bushing lead to complete reassembly.
Closing-solenoid contactor
If replacement of the double-break contacts is necessary,
the entire closing-solenoid contactor should be replaced as
follows:
1. Disconnect closing solenoid and fuse leads identified in
Figure 28.
TYPE R THREE-PHASE RECLOSER MAINTENANCE INSTRUCTIONS MN280026EN November 2015
3. Clean the mechanism of any carbon deposits with a
clean, lint-free cloth and rinse the unit in new oil. Be
sure the ball check valve in the bottom of the lockout
piston cylinder is free to operate. If it is necessary
to replace the hydraulic pump piston for any reason,
mark its vertical position relative to the operating link
identified in Figure 28. Note that the outer piston shell
is restrained from rotation by a small indentation.
4. Thread the new outer piston shell on the pump piston
and adjust to the position marked on the operating link
in step 3. Test for correct operation before staking the
outer shell to the piston.
NNote: Removal of the head casting is necessary before this
test can be performed. This procedure is required to
observe the lockout bar. See Head Casting Removal
section in this manual for head removal instructions.
Figure 28. Closing solenoid contactor and protective
fuses.
2. Remove two C rings to release pin that connects the
operating link to the toggle mechanism.
3. Remove the three hex-head cap screws, not shown,
that secure contactor to the frame. These screws are
located on the underside of the frame. Contactor is
now free to be removed.
4. Install the new contactor by reversing steps 1, 2, and 3.
Hydraulic pump and lockout piston
If the insulating oil has been allowed to become very dirty,
it may be advisable to remove the pump and lock-out piston
for cleaning. Removal is as follows:
1. With a 7/16-inch open-end wrench, remove the
two hex-head cap screws that secure the hydraulic
mechanism to the solenoid frame plate.
To test the hydraulic mechanism for correct operation:
Lower the unit into oil until the pump is covered
completely. Then operate the pump manually a few
times to remove any trapped air. Allow the lockout
piston to fully reset. Now manually trip and close the
recloser and observe the advance of the lockout bar.
After the next-to-last trip operation has occurred, one
end of the lockout bar should touch the control lever
trip latch.
5. If increased lockout-bar-travel is needed, unscrew the
outer piston shell to increase the effective length of
the piston. To decrease lockout-bartravel, screw the
shell farther onto the piston. Adjust in one-half turn
increments and repeat the test described in step 4 until
proper operating performance is achieved. When the
adjustment is completed set the new piston shell with
a small punch.
Time-delay units
CAUTION
Equipment damage. Keep work areas clean to prevent
debris from accumulating on or in the hydraulic mechanism during disassembly and reassembly procedures.
Failure to comply can result in hydraulic failure and
recloser misoperation.
T254.0
Maintenance of the time-delay units generally will be
confined to an inspection of fluid level. Some loss of fluid
level is normal and so this inspection should be made each
time periodic maintenance is performed. Refer to Figures 30
and 31.
Figure 29. Removing hydraulic pump and lockout mechanism.
2. Lift the mechanism housing as shown in Figure 29.
Both pistons and the fast reset valve rod will slide out.

Bushings
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
Figure 30. Time-delay unit for Type R reclosers between
serial nos. 3732 and 5514.
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
Maintenance of bushings is generally limited to an
occasional cleaning. However, if a bushing should become
cracked or broken, replace it as follows:
1. Remove hex nut and lock washer on the lower end of
the bushing to release the flexible lead straps.
2. Remove the three hex-head cap screws that secure the
bushing clamps (Figure 32) to the head casting. Lift the
bushing assembly up through the head casting.
3. An aluminum clamping ring cushions the pressure
between the bushing and bushing clamps. If it is in
good condition, the ring can be reused. Twist the ring to
slip it from the bushing.
Figure 31. Time-delay unit for type R reclosers above
serial no. 5513.
To check the fluid level, remove the filler plug located on
the side of the unit for Type R reclosers under serial number
5514. For Type R reclosers above serial number 5513,
remove the socket-head filler plug located on the side of
the brass adjusting block. A special kit, catalog number
KA806R2, is available to restore fluid level. This kit contains
an eye dropper and two ounces of the special time-delay
unit fluid (HFA—Hydraulic Fluid, Aircraft). Add enough fluid
to bring the level to the filler plug hole. Be sure to replace
the filler plug.
Closing solenoid fuses
To replace the fuses simply disconnect the long lead at
the closing-solenoid contactor, the short lead at the fuse
end, and loosen the mounting bolt. Refer to Figure 28.
Slide the fuse out and install the new one. A tag attached
to each closing solenoid coil indicates by color-band coding
the correct fuse to protect the coil. This information is also
tabulated on Table 3, in the Voltage Ratings section of this
manual.
Figure 32. Exploded view of bushing assembly.
4. Now the bushing assembly can be replaced completely,
14
TYPE R THREE-PHASE RECLOSER MAINTENANCE INSTRUCTIONS MN280026EN November 2015
or new porcelain only may be installed. If new porcelain
is to be used, unscrew the bushing terminal and draw
the bushing lead rod out the lower end of the porcelain.
Insert the rod in the new porcelain and replace the
bushing terminal. Be sure to use a new terminal gasket.
5. Replace the bushing assembly, using a new gasket
between the bushing and the head casting. When
securing the bushing clamps, be sure to tighten the
three bolts evenly, a little at a time.
NNote: When reconnecting bushings, position flexible leads
at least one-half inch from any vertical insulating
support.
Figure 34. Auxiliary switch linkage disconnection.
6. To reassemble, carefully lower head casting in place
with the tubular spacers mounted on the six lugs. Start
the six 1/2-inch bolts and tighten evenly to avoid binding
of the mechanism.
7. Engage the contact position indicator, non-reclosing
lever, and manual operating lever. Reconnect the
auxiliary switch if used.

Current ratings
Continuous current ratings of Type R reclosers can be
changed easily by installing new coils in the series trip
solenoids. Coils rated 25, 35, 50, 70, 100, 140, 160, 185,
225, 280, 400, or 400X are available.
When the recloser is equipped with standard trip coils,
tripping occurs at approximately 200 percent of full load
rating.
Tripping occurs at approximately 140 percent of full load
rating when alternate coils (400X) are used. For the method
of changing these coils, see the appropriate Series-Trip
Solenoid section of this manual.
Voltage ratings
Closing solenoid coils are available for eight voltage* ranges
from 2.4 to 14.4 kV. The method for changing these coils
is described in the Series-Trip Solenoid section of this
manual.
When a coil is changed, the protective fuses may also have
to be changed. Therefore, two fuses are shipped with each
replacement coil.
