1.2 General information
The purpose of this book is to provide instructions for unpack-
ing, storage, use, operation, and maintenance of Type VCP-W,
VCPW-SE, VCP-WC, and VCPW-ND vacuum circuit breakers. These
circuit breakers are horizontal drawout type removable interrupting
elements designed for use in VacClad-W Metal-Clad switchgear
and appropriate VCP-W modules. They provide reliable control and
protection for medium voltage electrical equipment and circuits. All
VCP-W circuit breaker elements are designed to ANSI Standards for
reliable performance, ease of handling, and simplified maintenance.
In addition, some VCP-W circuit breakers have been tested in accor-
dance with IEC Standards for applications around the world.
The VCPW-SE circuit breaker element is a VCP-W circuit breaker
designed specifically for special environment applications and operat-
ing conditions through 27 kV. The VCPW-ND circuit breaker element
is a narrow design VCP-W circuit breaker designed specifically for
use in 5 kV applications where floor space requirements would
not allow the industry standard 36 in. (914.4 mm) wide switchgear.
From this point on, all circuit breaker elements will be referred to as
Type VCP-W unless the reference is specific to a particular design.
The VCP-WC circuit breaker element is a VCP-W circuit breaker
designed and tested for extra capabilities beyond one or more of the
preferred ratings of the applicable ANSI Standard.

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 BREAKER ELEMENTS.
m
WARNING
THE CIRCUIT BREAKERS DESCRIBED IN THIS BOOK ARE DESIGNED AND
TESTED TO OPERATE WITHIN THEIR NAMEPLATE RATINGS. OPERATION
OUTSIDE OF THESE RATINGS MAY CAUSE THE EQUIPMENT TO FAIL,
RESULTING IN DEATH, BODILY INJURY, AND PROPERTY DAMAGE.
