1-2 GENERAL INFORMATION
The purpose of this book is to provide instructions for
unpacking, storage, use, operation and maintenance of
Type VCP-W Drawout and Type VCP-WR Fixed 38kV
Vacuum Circuit Breakers. They are similar in many ways
with the main differences centering around the
secondary/primary connection methods and the mounting
methods used. The differences are specifically addressed
in this book. The Type VCP-W is a horizontal drawout, roll
on the floor type removable interrupter element. The
Type VCP-WR is a fixed interrupter element with the
customer responsible for all required operational and
safety interfaces. Designed to ANSI Standards for
reliable performance, ease of handling, and simplified
maintenance, VCP-W and VCP-WR circuit breakers
provide reliable control and protection for electrical
equipment and circuits. In addition, these technologically
advanced circuit breakers provide higher insulation levels
in less space, thus reducing the overall switchgear size.
WARNING
SATISFACTORY PERFORMANCE OF THESE
BREAKERS IS CONTINGENT UPON PROPER
APPLICATION, CORRECT INSTALLATION AND
ADEQUATE MAINTENANCE. THIS INSTRUCTION
BOOK MUST BE CAREFULLY READ AND
FOLLOWED IN ORDER TO OBTAIN OPTIMUM
PERFORMANCE FOR LONG USEFUL LIFE OF THE
CIRCUIT BREAKERS.

SECTION 2: SAFE PRACTICES
2-1 RECOMMENDATIONS
Type VCP-W and VCP-WR Vacuum Circuit Breakers are
equipped with high speed, high energy operating
mechanisms. They are designed with several built-in
interlocks and safety features to provide safe and proper
operating sequences. Cell interlocks used with drawout
circuit breakers are meant to interact with the appropriate
cell interface and levering mechanism.
WARNING
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.
If the final breaker design is drawout, always remove
the breaker from the enclosure before performing any
maintenance. If the breaker is applied in a fixed con-
figuration, always make sure that primary and
secondary power are disconnected from the breaker.
Failure to do so could result in electrical shock leading to
death, severe personal injury or property damage.
Do not work on a drawout circuit breaker with a
secondary test coupler engaged. Failure to
disconnect the test coupler could result in an
electrical shock leading to death, personal injury
or property damage.
Do not work on a closed circuit breaker or a
breaker with closing springs charged. The closing
springs should be discharged and the main circuit
contacts open before working on the circuit
breaker. Failure to do so could result in cutting or
crushing injuries.
Do not use an open 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 lock-out and tagging rules of
the National Electrical Code and any other
applicable codes, regulations and work rules.
Do not leave a drawout circuit breaker in an
intermediate position in the cell. Always have the
circuit breaker either in the Disconnect/Test or
Connected position. Failure to do so could result in
a flash over and possible death, personal injury or
property damage.
• Always remove the maintenance tool from the
circuit breaker after charging the closing springs.
• Circuit breakers are equipped with safety
interlocks. Do Not remove, interfere with or in any
manner defeat them. This may result in death,
bodily injury or equipment damage.
Do not work on a circuit breaker suspended from a
lifting yoke or chains. Maintenance work should be
per-formed on a solid work surface, such as the
floor.

SECTION 3: RECEIVING, HANDLING AND
STORAGE
3-1 GENERAL
Type VCP-W and VCP-WR Vacuum Circuit Breakers
are subjected to complete factory production tests in
accordance with ANSI C37.09 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. Tools and accessories, such as
the maintenance tool, are shipped separately.
3-2 RECEIVING
If the circuit breaker is not to be used immediately but is
to be placed in storage, maximum protection can be
obtained by keeping it packed as shipped.
Upon receipt of the equipment, inspect the containers
for any signs of damage or rough handling. Open the
containers carefully to avoid any damage to the con-
tents. Use a nail puller rather than a crow bar when
required. When opening the containers, be careful to
save any loose items or hardware that may be other-
wise 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.
File claims immediately with the carrier if damage or loss
is detected and notify the nearest Eaton Office.
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 SOLID WORK
SURFACE CAPABLE OF SUPPORTING THE
CIRCUIT BREAKER.
VCP-W and VCP-WR 38kV Vacuum Circuit Breakers
are shipped mounted to a skid specially designed to
facilitate removal of the breaker. Refer to Figures 3-1
and 3-2 and proceed with the following steps:
WARNING
AFTER REMOVING THE BRACKETS USED TO
HOLD THE CIRCUIT BREAKER SECURELY TO
THE SHIPPING SKID AND ALL DURING THE
PROCESS OF MOVING THE CIRCUIT BREAKER
OFF OF THE SHIPPING SKID AND DOWN THE
RAMP TO THE FLOOR, TAKE SPECIAL
PRECAUTIONS TO INSURE THAT THE CIRCUIT
BREAKER IS MOVED SLOWLY AND UNDER
CONTROL TO AVOID ANY ACCIDENTS. THE
CIRCUIT BREAKER IS A LARGE DEVICE WHICH
COULD CAUSE SERIOUS BODILY INJURY IF IT IS
TIPPED OVER OR PERMITTED TO ROLL IN AN
UNCONTROLLED MANNER.
CAUTION
DO NOT PULL ON OR USE THE MAIN (PRIMARY)
CONDUCTORS AND OR THE PRIMARY
DISCONNECTS TO MANEUVER THE CIRCUIT
BREAKER IN ANY FASHION. FAILURE TO
COMPLY WITH THIS CAUTION COULD RESULT
IN SIGNIFICANT EQUIPMENT DAMAGE.
NOTICE
The VCP-W and VCP-WR 38kV shipping container
and pallet were specifically designed to facilitate
removal of the circuit breaker from its pallet and
container. Before proceeding, installation personnel
should be familiar with the procedures outlined in
Paragraph 3-3 entitled “Handling.”
3-3 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A PLAT-
FORM FOR PERFORMING MAINTENANCE, REPAIR
OR ADJUSTMENT OF THE CIRCUIT BREAKER OR
Page 10 I.B. 3A74792H08
Effective 09/2014
Figure 3-1 Circuit Breaker Shown Mounted with Ramp
Still in Shipping Position (VCP-W Only)
Step 1: VCP-WR breakers must be lifted from the
shipping pallet. Refer to paragraph 3-5 for
the optional lifting yoke used with an
overhead lifting device after all shipping
hardware used to hold the breaker to the
skid is removed.
Step 2: For VCP-W breakers, remove the vertically
mounted ramp from the shipping skid and
place it on the floor next to the skid. It
should be positioned with the highest part
of the ramp next to the side of the skid with
the front of the circuit breaker.
Step 3: Remove the shipping brackets used to hold
the circuit breaker to the skid. Use the
same shipping brackets and hardware to
attach the ramp to the shipping skid.
Step 4: Slowly move the circuit breaker forward and
down the ramp. Make certain that the
circuit breaker moves down the ramp
slowly and straight in line with the ramp.
Once the circuit breaker is on the floor, it
can be easily maneuvered via its integral
wheels.
VCP-W breakers can also be lifted using the
Figure 3-2 Circuit Breaker Shown Being Moved

Use (VCP-W Only)
3.4 STORAGE
If the circuit breaker is to be placed in storage, maxi-
I.B. 3A74792H08 Page 11
Effective 09/2014
optional lifting yoke described in Step 1
mum protection can be obtained by keeping it packed as
shipped. Before placing it in storage, checks should be
made to make sure that the circuit breaker is free from
shipping damage and is in satisfactory operating
condition.
The circuit breaker is shipped with its contacts open and
closing springs discharged. The indicators on the front
panel should confirm this. Insert the maintenance tool in
the manual charge socket opening (Figure 3-8).
Charge the closing springs by pumping the handle up
and down approximately 38 times until a crisp metallic
“click” is heard. This indicates that the closing springs
are charged and is shown by the closing spring
“charged” (yellow) indicator. Remove the maintenance
tool. Push the “manual close” button. The circuit breaker
will close as shown by the circuit breaker contacts
“closed” (red) indicator. Push the “manual trip” button.
The circuit breaker will trip as shown by the circuit
breaker contacts “open” (green) 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, dirt, falling objects and excessive moisture 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 air circulation to prevent condensation. If the
building is not heated, the same general rule for heat as
for outdoor storage should be applied.
3-5 TOOLS AND ACCESSORIES
Several tools and accessories, both standard and
optional are available for use with the circuit breaker.
Maintenance Tool (Standard): Used to charge closing
springs.
Lifting Yoke (Optional): Used to lift circuit breaker with
overhead lifting device.
