SECTION 1: INTRODUCTION
The purpose of this book is to provide instructions for
unpacking, storage, use operation and maintenance
of VCP-T drawout type and VCP-TR fixed type
Vacuum Circuit Breakers. VCP-T and VCP-TR are
compact vacuum interrupting elements designed for
applications such as: mine power centers, portable
power stations, fixed breaker or drawout switchgear
and portable generators, all without compromising
metal clad expectations. VCP-T and VCP-TR
breakers were specifically designed to provide proven
reliable performance in a small package. The circuit
breakers are available in voltage classes of 4.76, 8.25
and 15.0 kV. They are tested in accordance with ANSI
C37.04 and C37.09 (Table 1.1).
1-1 VCP-T and VCP-TR Vacuum Breaker Ratings
Refer to Tables 1.1 and 1.2 on pages 2 and 3.
The circuit breaker's nameplate provides complete
rating information. Reliable control and protection for
medium voltage equipment and circuits are achieved
through the use of VCP-T and VCP-TR Vacuum
Breakers.
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.
VCP-T and VCP-TR CIRCUIT BREAKERS ARE
PROTECTIVE DEVICES, AS SUCH, THEY ARE
MAXIMUM RATED DEVICES. THEREFORE, THEY
SHOULD NOT UNDER ANY CIRCUMSTANCES BE
APPLIED OUTSIDE THEIR NAMEPLATE RATINGS.

SECTION 2: SAFE PRACTICES
The circuit breakers are equipped with high speed,
high energy operating mechanisms. They are
designed with built-in safety interlocks to provide for
safe operation. In addition, other optional interlocks
are available depending upon the application. Refer to
Section 5 for additional inter lock informatio n. It is the
customers’ responsibility to insure that appropriate
interfaces with the breakers are provided and tests
conducted to adequately prove proper installation and
functioning.
WARNING
TO PROTECT THE PERSONNEL ASSOCIATED
WITH INSTALLATION, OPERATION, AND
MAINTENANCE OF THESE BREAKERS, THE
FOLLOWING PRACTICES MUST BE FOLLOWED:
Always make sure that primary and secondary
power are disconnected from a fixed breaker
before performing any maintenance. Failure to do
so could result in electrical shock leading to death,
severe personal injury and/or property damage.
Do not work on a closed breaker or a breaker with
closing springs charged. The closing springs
should be discharged and the main contacts open
before working on the 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. As
appropriate, use an isolation means and follow all
lock-out and tagging rules of the Local Electrical
Codes and any and all applicable codes,
regulations and work rules.
Only qualified persons, as defined in the Local
Electrical Codes, who are familiar with the
installation and maintenance of medium voltage
circuits and equipment, should be permitted to
work on these breakers.
Read these instructions carefully before
attempting any installation, operation or
maintenance of these breakers.
Always remove drawout type breakers from their
enclosure before performing any maintenance.
Failure to do so could result in electrical shock
leading to death, severe personal injury and/or
property damage.
Always ensure that drawout circuit breakers are in
one of their designed cell positions, such as
Connect, Test/Disconnect or Remove. A circuit
breaker permitted to remain in an intermediate
position could result in control circuits being
improperly connected resulting in electrical failures.
Breakers are equipped with safety interlocks. Do
Not defeat them. This may result in death, bodily
injury and/or equipment damage.
Do not work on a circuit breaker while
suspended from a lifting means. Maintenance
work should be performed on a properly
supported cart or table.

3-2.1 UNPACKING
SECTION 3: RECEIVING, HANDLING
AND STORA GE
VCP-T and VCP-TR 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.
3-1 RECEIVING
Until the breaker is ready for use, it is best NOT to
remove it from its container. If the breaker 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 from rough handling and/or
external damage incurred during the transportation
phase. Record any observed damage for reporting to
the transportation carrier and Eaton. All reports should
be as specific as possible and include the order
number and other applicable nameplate information.
Every effort is made to ensure that circuit breakers
arrive at their destination undamaged and ready for
installation. Care should be exercised, however, to
protect the breakers from impact at all times. Do not
remove protective packaging until the circuit breakers
are ready for inspection, testing and/or installation.
Before beginning to unpack new circuit breakers, read
and understand the directions. Unpacking a fixed circuit
breaker is described in the next paragraph in detail.
Unpacking a drawout circuit breaker is also simple to
accomplish and is not described here in detail. Just
proceed by carefully removing all packing material used
for protection during shipment and the fa steners used
to secure the drawout circuit breaker to its shipping
pallet.
When ready to inspect and install the circuit breaker,
carefully remove any banding straps and lift off the
cardboard box. Remove any additional packing material
and internally packed documentation. The circuit
breaker is mounted to a wooden shipping pallet. A
keyed metal clamp is used on each side of the circuit
breaker to hold it to the wooden pallet (Figure 3-1).
Remove the screws from the wooden pallet on each
side and lift up and out on the keyed metal clamps for
removal (Figure 3-2). The circuit breaker is now ready
to be rem ov e d f r o m i ts s hi p ping pallet. Save all
shipping hardware and packaging material for any
future shipments of the circuit breaker.
3-2 HANDLING
WARNING
DO NOT USE ANY LIFTING DEVICE AS A
PLATFORM FOR PERFORMING MAINTENANCE,
REPAIR OR ADJUSTMENT OF THE BREAKER,
FOR OPENING OR CLOSING THE CONTACTS OR
CHARGING THE SPRINGS. THE BREAKER MAY
SLIP OR FALL CAUSING SEVERE PERSONAL
INJURY. ALWAYS PERFORM MAINTENANCE,
REPAIR AND ADJUSTMENTS ON A WORKBENCH
CAPABLE OF SUPPORTING THE BREAKER.
Shipping containers are designed to be handled either
by use of a sufficiently strong rope sling and 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.

3-3 STORAGE
WARNING
THE CUSTOMER SHOULD READ AND
UNDERSTAND THE MATERIAL PRESENTED AND
ANY WARNINGS OR CAUTIONS OFFERED IN
THE INSTRUCTION BOOK BEFORE ANY
ATTEMPT IS MADE TO INTERFACE WITH THIS
CIRCUIT BREAKER.
IT IS IMPERATIVE THAT ALL APPLICABLE ANSI
STANDARDS BE COMPLIED WITH IN EVERY
RESPECT AND THAT NO COMPROMISES ARE
MADE WITH RESPECT TO THE ANSI
GUIDELINES OR INTENT.
UNDER NO CIRCUMSTANCES SHOULD
ALTERATIONS BE MADE TO EATON SUPPLIED
VCP-T OR VCP-TR CIRCUIT BREAKERS UNLESS
THE ALTERATION IS SPECIFICALLY ADDRESSED
IN AND PERMITTED BY THIS INSTRUCTION
BOOK.
If the circuit breaker is to be placed in storage,
maximum protection can be obtained by keeping it
packed as shipped. Before placing it in storage,
checks should be made to make sure that the breaker
is fre e from shipping damage and is in satisfactory
operating condition.
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.
