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.

proven
at 15kV. For sealed interrupters at high altitudes, switching voltage
is not de-rated.
(3) For higher RRRV contact Cutler-Hammer for more information.
(4) Breaker tested to 2700A single bank switching for momentary
load (Thermal derating must consider harmonic content of
current waveform).
(5) Breaker tested to 1 270A back to back switching for
