Replacement Circuit Breaker
SECTION 1: INTRODUCTION
This instruction booklet provides information on receiving and
handling, storage, installation, operation and maintenance of the
DST-2 VR-Series
+
vacuum replacement circuit breaker. The Vacuum
Replacement circuit breakers (also referred to as VR-Series
+
) are
designed to be used in existing Federal Pacific type DST-2 metal-clad
switchgear. The VR-Series
+
circuit breakers provide superior electrical
and mechanical performance as compared to the design ratings
of the original circuit breaker. VR-Series
+
circuit breakers provide
reliable control, protection and performance, with ease of handling
and maintenance. Like ratings of the VR-Series
+
circuit breakers are
interchangeable with each other.
The VR-Series
+
circuit breaker element offers:
•
10-year or 10,000 operation scheduled maintenance intervals.
When applied in “usual service conditions” as defined by IEEE
C37.04-1999, the VR-Series
+
circuit breaker element requires
maintenance only once every ten years or ten thousand
operations, which ever comes first.

See Inspection & Maintenance section in this booklet for details.
•
Increased mechanical endurance.
Circuit breakers in repetitive
duty applications offer 50% more operations over conventional
vacuum circuit breaker elements before parts replacement may
be needed.
•
Increased short circuit capability.
The VR-Series
+
circuit breaker
short circuit capability can be increased to 41 kA, provided a bus
bracing study is performed and the switchgear is adequately
braced to meet the requirements per IEEE C37.59.
Use this instruction bulletin in conjunction with the technical
information provided with the original equipment order which
includes electrical control schematic and wiring diagrams, outline
diagrams, installations plans, and procedures for installation and
maintenance of accessory items.
Satisfactory performance is dependent on proper application, correct
installation, and adequate maintenance. It is very important that
this installation and maintenance instruction booklet be read and
followed closely to achieve optimum performance and a long useful
circuit breaker life in its application.
1.1 VISUAL INSTRUCTION BOOKLET ESSENTIALS
Eaton provides additional documentation designed to enhance the
technical information provided in this instruction booklet for the
VR-Series
+
circuit breakers. The Visual Instruction Booklet Essentials
(VIBE) is a digital supplemental booklet featuring user interactive
content and informative videos intended to assist with the
maintenance of the VR-Series
+
circuit breaker. The VIBE document is
available for immediate download at www.eaton.com/VR-Series.
