1-2 GENERAL INFORMATION
The purpose of this book is to provide instructions for
unpacking, storage, use, operation and maintenance of
Type VCP-W 38kV Vacuum Circuit Breakers. They are
horizontal drawout, roll on the floor type removable
interrupting elements ideal for use in new metal-clad
switchgear, as well as for modernization and life exten-
sion of existing switchgear. Designed to ANSI Stan-
dards for reliable performance, ease of handling, and
simplified maintenance, VCP-W 38kV Vacuum Circuit
Breakers provide reliable control and protection for elec-
trical equipment and circuits. In addition, these techno-
logically advanced circuit breakers provide higher insu-
lation levels in less space, thus reducing the overall
switchgear size.
SATISFACTORY PERFORMANCE OF THESE CIR-
CUIT BREAKERS IS CONTINGENT UPON PROPER
APPLICATION, CORRECT INSTALLATION AND
ADEQUATE MAINTENANCE. THIS INSTRUCTION
BOOK MUST BE CAREFULLY READ AND FOL-
LOWED IN ORDER TO OBTAIN OPTIMUM PERFOR-
MANCE FOR LONG USEFUL LIFE OF THE CIRCUIT
BREAKERS.
