The purpose of this book is to provide instructions for
unpacking, storage, installation, operation and
maintenance of Type DHP-VR Vacuum Replacement
Circuit Breakers. They are horizontal draw out type
removable interrupting elements for use in existing DHP
Metal-Clad Switchgear. DHP-VR Circuit Breakers provide
reliable control, protection and performance, with ease of
handling and maintenance. Like ratings are
interchangeable with each other.
1-1 AVAILABLE DHP-VR BREAKERS
Refer to Table 1.1.
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 DHP-VR BREAKERS ARE PROTECTIVE
DEVICES, AS SUCH, THEY ARE MAXIMUM RATED
DEVICES. THEREFORE, THEY SHOULD NOT
UNDER ANY CIRCUMSTANCE BE APPLIED OUT-
SIDE THEIR NAMEPLATE RATINGS.
