Section 1: Introduction - Eaton VCP-TL Series Instructions For The Use, Operation And Maintenance

SECTION 1: INTRODUCTION

The purpose of this book is to provide instructions for
unpacking, storage, use, operation and maintenance of
VCP-TL drawout type and VCP-TRL fixed type Vacuum
Circuit Breakers with linear actuator mechanisms. VCP-
TL and VCP-TRL are compact vacuum interrupting
elements designed for applications such as: mine power
centers, portable power substations, fixed breaker or
drawout switchgear and portable generators, all without
compromising metal clad expectations. VCP-TL and
VCP-TRL breakers were specifically designed to pro-
vide proven reliable performance in a small package.
The circuit breakers are available in voltage classes of
4.76, 8.25 and 15.0 kV. They are tested in accordance
with ANSI C37.04 and C37.09 (Table 1.1).
1-1 VCP-TL and VCP-TRL Vacuum Breaker Ratings
Refer to Table 1.1 on page 2.
The circuit breaker's nameplate provides complete
rating information. Reliable control and protection for
medium voltage equipment and circuits are achieved
through the use of VCP-TL and VCP-TRL Vacuum
Breakers.
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.
VCP-TL and VCP-TRL CIRCUIT BREAKERS ARE
PROTECTIVE DEVICES, AS SUCH, THEY ARE
MAXI-MUM RATED DEVICES. THEREFORE, THEY
SHOULD NOT UNDER ANY CIRCUMSTANCES BE
APPLIED OUTSIDE THEIR NAMEPLATE RATINGS.
