1-2 GENERAL INFORMATION

The purpose of this book is to provide instructions for
unpacking, storage, use, operation and maintenance of
Type VCP-W, VCPW-SE, 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, VCPW circuit breakers are
tested to both ANSI and IEC Standards for application
around the world.

The VCPW-SE circuit breaker element is a VCP-W
circuit breaker designed specifically for special
environment applications and operating 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 inch 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
