WARNING: Before installing, operating,
maintaining or testing this equipment,
carefully read and understand the contents
of this manual. Improper operation, handling
or maintenance can result in death, severe
personal injury or equipment damage.
WARNING: Hazardous voltage. Contact
with high voltage will cause serious
personal injury or death. Follow all locally
approved safety procedures when working
around high-voltage lines and equipment.
WARNING: Hazardous voltage. Do not
rely on the contact position indicator
to determine that the line has been
de-energized. Always establish a visible
disconnect and establish person grounds
when performing de-energized line work.
Failure to follow proper safety practices can
result in contact with high voltage, which
can cause death or severe personal injury.
WARNING: Hazardous voltage. Recloser
and control must be solidly grounded.
Improper grounding can result in contact
with high voltage, which will cause severe
personal injury or death and equipment
damage. Disconnecting the control cable
when the recloser is energized could result
in high voltage on the pins if the recloser
tank is not grounded as specified.
WARNING: When testing at high voltage,
the MVR and high-voltage test equipment
should be in a test cage or similar
protective area to prevent accidental
contact with the high-voltage parts. All
equipment needs to be solidly grounded.
Failure to comply can result in death,
severe personal injury and equipment
damage.
CAUTION: All MVRs are sealed and leak
tested prior to shipment to prevent moisture
ingress. Do not open the lower cover as it is
possible that the MVR will not reseal when
the cover is closed. While the diaphragm
will keep moisture from ever entering the
high-voltage chamber, excessive moisture
ingress
could cause damage to the magnetic
actuator
mechanism and misoperation.
CAUTION: Do not remove and replace
the side terminal in the field. The MVR
incorporates a unique diaphragm
technology that fully encapsulates the
high-voltage chamber in the MVR. The side
terminal must be vented during installation
and then sealed to prevent pressure
build-up against the diaphragm during the
installation process. Improper installation
may cause equipment damage and possible
personal injury.
CAUTION: Rotating the terminal connector
without properly loosening the connector
will apply excessive force on the terminal
stud and could damage the interrupter
assembly.
CAUTION: The complete recloser
system, including control, requires routine
inspection and maintenance if damage is
found to ensure proper operation. If it is not
maintained, it may fail to operate properly.
Improper operation may cause equipment
damage and possible personal injury.
CAUTION: Follow approved safety
practices when lifting and mounting the
MVR. Use lifting rings on three-phase units
and lift smoothly, limiting shifting to avoid
damage. Do not lift three-phase MVRs by
the side terminals as damage could result.
CAUTION: Do not energize the recloser for
service until all control settings have been
properly programmed and verified. Refer
to the appropriate SEL®control manual
for programming procedures. Failure to
comply may result in control and recloser
misoperation.
"EEJUJPOBM*OGPSNBUJPO These instructions
are not intended to cover all details or
variations in the equipment, procedures or
processes described. Nor are they designed
to provide directions for meeting every
possible contingency during installation,

Acceptance and Initial Inspection
Each MVR is shipped completely assembled, pretested and in the closed position from the factory.
Upon arrival, uncrate the unit (refer to Crate Removal and Visual Inspection section). Check the unit does not have
missing parts and it is in the closed position. Also check the unit for any damage that may have occurred during
shipping. Should any damage be found, file a claim with the shipping carrier and contact the factory or your local
Thomas & Betts representative.
Crate Removal and Visual Inspection
Packaging may differ depending on the units being shipped. Carefully remove the MVR from its packaging. In the case of
units shipped in crates, remove the outer crate top by removing the screws or bolts attaching it to the skid. Then unbolt the
recloser from the skid. It is then possible to lift the unit directly off the skid with a hoist. Take care when opening packaging
not to nick or cut the EPDM/silicone insulation on the MVR.
After uncrating, visually inspect the MVR for any shipping damage, including the insulation, bushings, trip lever, mounting
frame, etc. If damage has occurred, please file a claim with the shipping carrier immediately and contact your local Thomas
& Betts representative. Do not attempt to install the equipment with damages or missing parts.
Lifting
Single-phase units can be lifted and moved by
hand or by fastening a loop around the main
body. Three-phase units must be lifted using
the lifting rings.
Follow all approved safety practices when making
hitches and lifting the equipment. Lift the MVR
smoothly by using the four lifting rings on the
recloser as shown. Do not allow the unit to shift.
Be careful that the lifting sling exerts no forces
on the side terminals or on the individual poles.
CAUTION: Follow approved safety practices when lifting and mounting the MVR. Use lifting rings on three-phase units and
lift smoothly, limiting shifting to avoid damage. Do not lift three-phase MVRs by the side terminals as damage could result.

Surge Arrester Mounting
Each single-phase recloser mounting ring has a provision for mounting an optional
bracket on either side of the recloser to support two customer-supplied arresters
(one line-side and one load-side). Refer to the supplied recloser drawings for specific
installation dimensions. Alternate configurations are shown at right.
Three-phase reclosers have provisions for mounting an optional front bracket to
support three load-side, customer-provided surge arresters. A rear mounting bracket
for three additional line-side arresters is also available as an option as well as an
option to mount multiple transformers. Refer to the supplied recloser drawings for
specific installation dimensions. See example at right.
Since arresters are designed to provide lightning overvoltage protection, they
should be mounted as close as practical to the recloser if the standard arrester
brackets are not used.
Control Wiring
Control power must meet the requirements stated on the drawings supplied with the
recloser control. Please refer to the appropriate SEL®control manual. Each recloser and
control cabinet assembly comes with standard interconnection cables that are keyed at
each end to assure proper installation. Please see figures below for descriptions of the

Grounding
To ensure the maximum amount of protection for internal
control components during possible power surge events,
the recloser and control cabinet need to be solidly grounded
together. The recloser ground conductor must be connected
to the supplied #10–2 AWG ground lug located on the
recloser’s frame base. All separate grounds should be
connected to the main ground wire. All connections to the
SEL®control (including the control cable, which contains a
ground) must be routed in close proximity to and parallel to
the main ground paths and should be approximately equal
in length. When using a power module with a 351R or 351R
Falcon, the power module box must also be grounded. See
Set-Up on QBHFfor a visual representation.
WARNING: Hazardous voltage. Recloser and control must
be solidly grounded. Improper grounding can result in
contact with high voltage, which will cause severe personal
injury or death and equipment damage. Disconnecting the
control cable when the recloser is energized could result in
high voltage on the pins if the recloser tank is not grounded
as specified.
Voltage Sensor Set-Up
All Elastimold®MVRs come with pre-calibrated, load-
side capacitive voltage sensors that are capable of
measuring amplitude and phase angle with an accuracy
of approximately 3% under normal operating conditions
(-10˚ C to 45˚ C) and +/-5% at extreme conditions
(-40˚ C to 65˚ C).
For 3-phase MVRs, optional pre-calibrated line-side
resistive voltage sensors are also available and are
capable of measuring the voltage with a higher accuracy
of approximately 1%. All sensors require an 8VAC LEA
voltage sensor input on the SEL®651Rx2 control. Refer
to the Elastimold®Source Side Voltage Sensor (ESSVS)
Installation Instructions for mounting details. The ESSVS
are not used with the SEL®351R, 351R Falcon or 351RS
Kestrel Controls.
Electronic Operation Test
Using the controller, open and close the MVR electrically by
pressing the marked open and close buttons. Confirm that
the selected button is in agreement with the position indicator
on the control panel as well as the recloser position indicator.
The recloser position indicator is located on the bottom of the
recloser as shown below.
MVRs are designed to operate with a total circuit resistance
of 6.5–7.3 ohms across the TRIP/CLOSE pins on the SEL®
control interface.
SEL is a registered trademark of Schweitzer Engineering Laboratories, Inc.
CAUTION: Do not energize the recloser for service until all
control settings have been properly programmed and verified.
Refer to the appropriate SEL®control manual for programming
procedures. Failure to comply may result in control and recloser
misoperation.
WARNING: Hazardous voltage. Do not rely on the contact
position indicator to determine that the line has been
de-energized. Always establish a visible disconnect and
establish grounds when performing de-energized line work.
Failure to follow proper safety practices can result in
contact with high voltage, which can cause death or
severe personal injury.

Vacuum Interrupter Tests
Every recloser is quality checked and tested before leaving the factory to assure
it meets all design specifications. In order to verify proper operating condition after
shipment and before installation, two tests should be performed to evaluate the
vacuum contacts. These tests should be performed across each module separately
and can be performed again, as desired, throughout the life of the recloser.
WARNING: When testing at high voltage, the MVR and high-voltage test equipment
should be in a test cage or similar protective area to prevent accidental contact
with the high-voltage parts. All equipment needs to be solidly grounded. Failure
to comply can result in death, severe personal injury and equipment damage.
"$)JHI1PUFOUJBM5FTULoss of vacuum results in complete breakdown across open vacuum contacts at
voltages below 30kV RMS. Only AC high potential testing is meaningful. With the
recloser in the OPEN position, apply 30kV RMS across each individual contact for
15 seconds. To avoid possible generation of X-rays, do not apply more than 30kV RMS.
During the high potential testing, self-extinguishing, momentary breakdowns lasting only
a few seconds may occur. These breakdowns are not significant but can result in false
indication of vacuum loss if the test set uses a high-speed overload relay or breaker.
During normal operation with the recloser in service, loss of vacuum or a defective
module may be indicated by excessive AM radio noise with the recloser open or
by measuring a difference in surface temperatures (differential of more than 5º C
temperature rise above normal ambient) between poles on the same recloser.
When loss of vacuum occurs, contact resistance will typically increase.
$POUBDU3FTJTUBODF5FTUWith the recloser in the CLOSED position, measure the resistance across each module.
Resistance values should be less than 200 micro-ohms. If higher resistance values are
measured, contact your local Thomas & Betts representative.

Manual Trip Lever Test
With the switch closed, pull down the yellow trip lever as shown in center photo at right and
verify that the recloser opens. The position indicators located on the bottom of the recloser
will be GREEN for OPEN. The manual trip lever will remain in the down position until returned
to the up position. When in the down TRIPPED position, the manual trip will block all close
operations until it is manually restored to the up NORMAL position. When using the standard
SEL® 651Rx2, the control standard settings will also send a signal to open when the manual
trip handle is pulled. The recloser can be closed once the manual trip handle has been
restored to the normal position by pressing the close button on the control.

Operation
The recloser receives the
necessary signal to open and
close from the control circuitry.
For specific information
concerning the operation of
the control and how to change
settings, please refer the
appropriate SEL®control manual.
$5BOE7PMUBHF4FOTPSWhen
using standard SEL®settings files,
the CT ratio will already be preset
to 1000:1 and the voltage sensors
will come pre-calibrated (used
on the 651Rx2 only). If standard
settings files are not used, the
CT input in the SEL®control will
need to be adjusted to 1000:1. All
voltage sensors require an 8VAC
LEA input and are pre-calibrated
to a ratio of 10kV on the line to
1VAC into the SEL®control.
3FDMPTF4FRVFODFFor specific
information on how to adjust
settings and curves, please refer
to the appropriate SEL®control
manual. Note that certain SEL®
controls limit the number of
reclose sequences when AC
or battery is not present.
Please consult Schweitzer
Engineering Laboratories.
31PXFS.PEVMFFor
specifications, please refer to
the Power Module Box Installation
and Operation Instructions.
Maintenance
CAUTION: The complete recloser system, including control, requires routine inspection
and maintenance if damage is found to ensure proper operation. If it is not maintained,
it may fail to operate properly. Improper operation may cause equipment damage and
possible personal injury.
The Elastimold®MVR is designed to be maintenance free under normal operating
conditions, and the EPDM/silicone insulation is not prone to the cracking or chipping
that sometimes occurs with porcelain or epoxy insulators. However, should damage
occur as a result of an external event, in most cases it is possible to replace the
damaged components due to the modular design of the recloser. Both the top and
bottom silicone shed, as well as the side terminal, can be removed and replaced if
damaged by external arcing, a knife cut, etc. If damage extends to the main body
of the pole, the pole in each phase can be replaced individually. If damage occurs,
please contact Thomas & Betts customer service. If it becomes necessary to clean
the main body or sheds, recommended cleaning agents are soap and warm water
or isopropyl alcohol.

CAUTION: A ll MVRs are sealed and
leak tested prior to shipment to prevent
moisture ingress. Do not open the lower
cover as it is possible that the MVR will
not reseal when the cover is closed.
While the diaphragm will keep moisture
from ever entering the high-voltage
chamber, excessive moisture ingress
could cause damage to the magnetic
actuator mechanism and misoperation .
CAUTION: Do not remove and replace
the side terminal in the field. The MVR
incorporates a unique diaphragm
technology that fully encapsulates the
high-voltage chamber in the MVR. The
side terminal must be vented during
installation and then sealed to prevent
pressure build-up against the diaphragm
during the installation process. Improper
installation may cause equipment
damage and possible personal injury.
