SECTION 1: INTRODUCTION

The purpose of this book is to provide instructions for

unpacking, storage, use, operation and maintenance of

Type VCP-WR Vacuum Circuit Breakers. VCP-WR is a

vacuum interrupting element designed for value added

construction. The VCP-WR Red Line family of circuit

breaker elements is comprised of three element types

(Series 18, Series 20 and Series 29). The nominal

widths are 18 inches for Series 18, 20 inches for Series

20 and 29 inches for Series 29. Any one of the three

available elements can be used as a retrofitting drawout

breaker when the customer provides and combines the

appropriate cell interface, truck, levering mechanism,

secondary connections, interlocks and other accessory

items with the VCP-WR element. VCP-WR elements

can also be used for fixed breaker applications with

others responsible for all required interfaces.

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 BREAKERS.

TYPE VCP-WR BREAKERS ARE PROTECTIVE

DEVICES, AS SUCH, THEY ARE MAXIMUM RATED

DEVICES. THEREFORE, THEY SHOULD NOT

UNDER ANY CIRCUMSTANCES BE APPLIED OUT-

SIDE THEIR NAMEPLATE RATINGS.
