VR-Ser ies+ Replacement Circuit Breaker
SECTION 1: INTRODUCTION
This instruction booklet provides information on receiving and
handling, storage, installation, operation and maintenance of the
DST-2 VR-Series+ vacuum replacement circuit breaker. The Vacuum
Replacement circuit breakers (also referred to as VR-Series+) are
designed to be used in existing Federal Pacific type DST-2 metal-clad
switchgear. The VR-Series+ circuit breakers provide superior electrical
and mechanical performance as compared to the design ratings
of the original circuit breaker. VR-Series+ circuit breakers provide
reliable control, protection and performance, with ease of handling
and maintenance. Like ratings of the VR-Series+ circuit breakers are
interchangeable with each other.
The VR-Series+ circuit breaker element offers:
• 10-year or 10,000 operation scheduled maintenance intervals.
When applied in “usual service conditions” as defined by IEEE
C37.04-1999, the VR-Series+ circuit breaker element requires
maintenance only once every ten years or ten thousand
operations, which ever comes first.
ote:N See Inspection & Maintenance section in this booklet for details.
• Increased mechanical endurance. Circuit breakers in repetitive
duty applications offer 50% more operations over conventional
vacuum circuit breaker elements before parts replacement may
be needed.
• Increased short circuit capability. The VR-Series+ circuit breaker
short circuit capability can be increased to 41 kA, provided a bus
bracing study is performed and the switchgear is adequately
braced to meet the requirements per IEEE C37.59.
Use this instruction bulletin in conjunction with the technical
information provided with the original equipment order which
includes electrical control schematic and wiring diagrams, outline
diagrams, installations plans, and procedures for installation and
maintenance of accessory items.
Satisfactory performance is dependent on proper application, correct
installation, and adequate maintenance. It is very important that
this installation and maintenance instruction booklet be read and
followed closely to achieve optimum performance and a long useful
circuit breaker life in its application.

SECTION 2: SAFE PRACTICES
VR-Series+ circuit breakers are equipped with high speed, high
energy operating mechanisms. They are designed with several builtin interlocks and safety features to provide safe and proper operating
sequences.
DANGER
TO PROTECT THE PERSONNEL ASSOCIATED WITH INSTALLATION,
OPERATION, AND MAINTENANCE OF THESE CIRCUIT BREAKERS, THE
FOLLOWING PRACTICES MUST BE FOLLOWED:
•
Only qualified persons, as defined in the National Electrical
Safety Code, who are familiar with the installation and
maintenance of medium voltage circuits and equipment,
should be permitted to work on these circuit breakers.
•
Read these instructions carefully before attempting any
installation, operation or maintenance of these circuit
breakers.
•
Always remove the circuit breaker from the enclosure before
performing any maintenance. Failure to do so could result in
electrical shock leading equipment failure, resulting in death,
severe personal injury, equipment damage and/or improper
operation.
•
Do not work on a circuit breaker with the secondary test
coupler engaged. Failure to disconnect the test coupler could
result in an electrical shock leading to death, severe personal
injury, equipment damage and/or improper operation.
•
Do not work on a closed circuit breaker or a circuit breaker
with closing springs charged. The closing spring should be
discharged and the main contacts open before working on
the circuit breaker. Failure to do so could result in cutting or
crushing injuries.
•
Do not use a circuit breaker by itself as the sole means of
isolating a high voltage circuit. Remove the circuit breaker
to the ‘Disconnect’ position and follow all lockout and
tagging rules of the National Electrical Code and any and all
applicable codes, regulations and work rules.
•
Do not leave the circuit breaker in an intermediate position
in the circuit breaker compartment. Always have the circuit
breaker either in the ‘Test’ or ‘Connect’ position. Failure to do
so could result in a flash over causing the equipment to fail,
resulting in death, severe personal injury, equipment damage
and/or improper operation.
•
Always remove the maintenance tool from the circuit breaker
after charging the closing springs.
•
Circuit breakers are equipped with safety interlocks. Do not
defeat them. This may result in equipment failure, resulting
in death, severe personal injury, equipment damage and/or
improper operation.

SECTION 3: RECEIVING, HANDLING, AND
STORAGE
VR-Series+ circuit breakers are subjected to complete factory
production tests and inspection before being packed. They are
shipped in packages designed to provide maximum protection to the
equipment during shipment and storage and at the same time to
provide convenient handling. Accessories such as the maintenance
tool, code plate, (if applicable) etc. are shipped with the circuit
breaker.
3.1 RECEIVING
Until the circuit breaker is ready to be delivered to the switchgear
site for installation, DO NOT remove it from the shipping crate. If the
circuit breaker is to be placed in storage, maximum protection can
be obtained by keeping it in its crate.
Upon receipt of the equipment, inspect the crates for any signs of
damage or rough handling. Open the crates carefully to avoid any
damage to the contents. Use a nail puller rather than a crow bar
when required.
When opening the crates, be careful that any loose items or
hardware are not discarded with the packing material. Check the
contents of each package against the packing list.
Examine the circuit breaker for any signs of shipping damage
such as broken, missing or loose hardware, damaged or deformed
insulation and other components. If damaged or loss is detected,
file claims immediately with the carrier and notify an Eaton
representative.
Figure 3.1.a. Typical Tools and Accessories
Figure 3.1.b. Rotary Racking Handle
Tools and Accessories
Maintenance Tool (Style# 94C9506G01): This tool is used to
manually charge the closing springs. One maintenance tool is
provided with each vacuum replacement circuit breaker.
Rotary Racking Handle (Style# 94B4102G21): Rotary racking is
possible utilizing a speed-handle, suitable extensions and a standard
3/4” socket. One rotary racking handle is provided per order. If
necessary, additional racking handles may be purchased directly
from Eaton. This handle is used with the rotary racking system for
insertion and removal.
Levering Handle: The original DST-2 levering handle is used to assist
in moving the circuit breaker into and out of the cell. However, it
cannot be used with the rotary racking system. Its use is illustrated
in section 5 of this manual.
Secondary Connection Block Extension Cable: The extension
cable can be used to connect the circuit breaker to a “test cabinet”
or to the switchgear cell’s secondary receptacle block so that
the breaker can be electrically operated while not installed in the
switchgear cell. This extension cable is the same one provided with
the original Federal Pacific breaker and is therefore not included as
part of the vacuum replacement breaker
Lifting Strap (Style# 94B1194G01): Optional item recommended
for lifting the DST-2-VR+ circuit breaker.

3.2 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLATFORM FOR PERFORMING
MAINTENANCE, REPAIR OR ADJUSTMENT OF THE CIRCUIT BREAKER OR
FOR OPENING, CLOSING THE CONTACTS OR CHARGING THE SPRINGS.
THE CIRCUIT BREAKER MAY SLIP OR FALL CAUSING SEVERE PERSONAL
INJURY. ALWAYS PERFORM MAINTENANCE, REPAIR AND ADJUSTMENTS
ON A WORKBENCH CAPABLE OF SUPPORTING THE CIRCUIT BREAKER
TYPE.
VR-Series+ circuit breaker shipping containers are designed to be
handled either by use of an overhead lifting device or by a fork lift
truck. If containers must be skidded for any distance, it is preferable
to use roller conveyors or individual pipe rollers.
Once a circuit breaker has been inspected for shipping damage, it
is best to return it to its original shipping crate until it is ready to be
installed in the metal-clad switchgear.
When the circuit breaker is ready for installation, a lifting harness in
conjunction with an overhead lift or portable floor lift can be used to
move the circuit breaker. If the circuit breaker is to be lifted, position
the lifting device over the circuit breaker and insert the lifting harness
hooks into the circuit breaker side lifting points and secure (lifting
straps should have at least a 1000lbs lift capacity). Be sure the hooks
are firmly attached before lifting the circuit breaker. Stand a safe
distance away from the circuit breaker while lifting and moving.
Figure 3.2. Lifting DST-2-VR
+
3.3 STORAGE
If the circuit breaker is to be placed in storage, maximum protection
can be obtained by keeping it in the original shipping crate. Confirm
that the circuit breaker is free from shipping damage and is in
satisfactory operating condition before placing it in to storage.
The circuit breaker is shipped with its contacts open and closing
springs discharged. The indicators on the front cover should confirm
this. Insert the end of the maintenance tool into the manual charge
socket opening and charge the closing springs by moving the
handle up and down the full range of motion. When charging is
complete the ratchet will no longer advance and the spring charged
/ discharged indicator displays ‘Charged’. (Figure Set 3.3). Remove
the maintenance tool. Push the “manual close” operator. The circuit
breaker will close as shown by the circuit breaker contacts ‘Closed’
indicator. Push the “manual trip” operator. The circuit breaker will
trip as shown by the circuit breaker contacts ‘Open’ indicator. After
completing this initial check, leave the closing springs ‘Discharged’
and circuit breaker contacts ‘Open’.
Outdoor storage is NOT recommended. If unavoidable, the outdoor
location must be well drained and a temporary shelter from sun,
rain, snow, corrosive fumes, dust, dirt, falling objects, excessive
moisture, etc. must be provided. Containers should be arranged
to permit free circulation of air on all sides and temporary heaters
should be used to minimize condensation. Moisture can cause
rusting of metal parts and deterioration of high voltage insulation.
A heat level of approximately 400 watts for each 100 cubic feet of
volume is recommended with the heaters distributed uniformly
throughout the structure near the floor.
Indoor storage should be in a building with sufficient heat and
circulation to prevent condensation. If the building is not heated, the
same general rule for heat as for outdoor storage should be applied.
