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

3.4 STORAGE

If the circuit breaker is to be placed in storage, maxi-

I.B. 3A74792H08 Page 11

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.
