SECTION 1: INTRODUCTION
The purpose of this book is to provide instructions for
unpacking, storage, installation, operation and mainte-
nance of Types W-VAC, W-VACR, and W-VACW
Vacuum Circuit Breakers. They are a horizontal drawout
type removable interrupting element design, unless
there is an “R” in the designation.The “R” as in W-VACR
indicates a fixed breaker configuration. They were
designed specifically to IEC 56 Standards for reliable
performance. All types can be applied in single tier or
double tier switchgear applications, with the basic
breaker element applicable to retrofitting. Reliable con-
trol and protection are achieved though the use of the
W-VAC family of breakers.
1-1 W-VAC, W-VACR AND W-VACW RATINGS
SATISFACTORY PERFORMANCE OF THESE
BREAKERS IS CONTINGENT UP-ON 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.
TYPES W-VAC, W-VACR AND W-VACW BREAKERS
ARE PROTECTIVE DEVICES, AS SUCH, THEY ARE
MAXIMUM RATED DEVICES. THEREFORE, THEY
SHOULD NOT UNDER ANY CIRCUMSTANCES BE
APPLIED OUTSIDE THEIR NAMEPLATE RATINGS.
