Effective Mar 2018
The purpose of this book is to provide instructions for unpacking, storage, use, operation and maintenance of Type VCP-WL Vacuum Circuit Breakers. These circuit breakers are horizontal drawout type removable interrupting elements designed for use in VacClad-W Metal­Clad Switchgear and appropriate VCP-WL modules. The Type VCP-WL Vacuum Circuit Breakers are designed to operate as a roll-in replacement for Type VCP-W Vacuum Circuit Breakers. They provide reliable control and protection for medium voltage electrical equipment and

circuits. All VCP-WL circuit breaker elements are designed to ANSI Standards for reliable performance, ease of handling and simplified maintenance.
WARNING
SATISFACTORY PERFORMANCE OF THESE BREAKERS AND OR MINIMOD 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 MINIMOD. EQUIPMENT TO FAIL, RESULTING IN DEATH, BODILY INJURY AND PROPERTY DAMAGE.

2-1 RECOMMENDATIONS
Type VCP-WL Vacuum Circuit Breaker Elements are equipped with high speed, high energy operating mechanisms, and are designed with several built-in inter-
Pag e vi IB13 1021EN
locks and safety features to provide safe and proper operating sequences.
WARNING
TO PROTECT THE PERSONNEL ASSOCIATED WITH INSTALLATION, OPERATION, AND MAINTENANCE OF THESE CIRCUIT BREAKER ELEMENTS, THE FOLLOWING PRACTICES MUST BE FOLLOWED:
Only qualified personnel, as defined in the local electrical code, who are familiar with the installation and maintenance of medium voltage circuits and equipment, should be permitted to work on these circuit breaker elements.
Read these instructions carefully before attempting any installation, operation or maintenance of these breakers.
Always remove the breakers from the enclosure before performing any maintenance. Failure to do so could result in electrical shock leading to death, severe personal injury or property damage.
tripping. Carelessness could cause the circuit breaker to fall from the rails resulting in personal injury to those in the area.
Do not work on a closed breaker or a breaker with capacitor bank charged. The capacitor bank should be discharged and the main contacts open before working on the breaker. The capacitor bank will discharge after control power is removed. Failure to do so could result in severe injury or death.
Do not use a circuit breaker by itself as the sole means of isolating a high voltage circuit. Remove the breaker to the DISCONNECT position and follow good lockout and tagging rules, as well as all applicable codes, regulations and work rules.
Do not leave the breaker in an intermediate position in the cell. Always have the breaker either in the TEST or CONNECTED position. Failure to do so could result in a flash over and possible death, personal injury or property damage.
Breakers are equipped with safety interlocks. Do not defeat them. This may result in death, bodily injury or equipment damage.
BE EXTREMELY CAREFUL while the circuit breaker is on the extension rails. Use provided rail clamps to firmly hold the circuit breaker on the extension rails while performing such activities as charging, closing and
SECTION 3: RECEIVING, HANDLING AND STORAGE
IB13 1021EN P ag e vii
3-1 GENERAL
Type VCP-WL Vacuum Circuit Breaker Elements 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.
3-2 RECEIVING
If the circuit breaker element 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 otherwise discarded with the packing material. Check the contents of each package against the packing list.
Examine the circuit breaker element 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.
breaker element side openings with the lifting hole toward the interrupters. Once the lifting yoke is securely seated in the holes, the breaker element can be carefully lifted and moved.
3-4 STORAGE
If the circuit breaker element 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 element is free from shipping damage and is in satisfactory operating condition.
The circuit breaker element is shipped with its contacts open and capacitor bank discharged. The indicators on the front panel should confirm this.
Outdoor storage of the breaker element 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.
3-3 HANDLING
CAUTION
DO NOT USE ANY LIFTING DEVICE AS A PLATFORM FOR PERFORMING MAINTENANCE, REPAIR OR ADJUSTMENT OF THE BREAKER OR FOR OPENING, CLOSING THE CONTACTS OR CHARGING THE SPRINGS. THE CIRCUIT BREAKER ELEMENT MAY SLIP OR FALL CAUSING SEVERE PERSONAL INJURY. ALWAYS PERFORM MAINTENANCE, REPAIR AND ADJUSTMENTS ON A SOLID WORK SURFACE CAPABLE OF SUPPORTING THE BREAKER ELEMENT.
When a breaker element is ready for installation, a lifting yoke in conjunction with an overhead lifter or portable floor lifter can be used to move a breaker element. When a breaker element is to be lifted, position the lifting yoke over the breaker element and insert the lifter tabs into the
