Replacement Circuit Breakers
- Eliminate the obsolete
air magnetic technology in your system
- Accommodate larger
electrical distribution systems and protect your
- Cut maintenance costs by
up to 90% and avoid costly downtime
- Reduce the failures
caused by normal wear and aging of contacts,
mechanisms, and dielectric deterioration of primary
bushings and arc chutes
- Are manufactured to
exceed the most stringent ANSI requirements
Obsolescence Add Up
|Outdated technology is
surprisingly costly to maintain. Asbestos arc
chutes, bushings, and arc gases can create environmental
and safety liabilities. Dielectric deterioration
of moisture-absorbing components (bushings) reduces
reliability; replacement parts are often expensive and
hard to locate. Demanding maintenance procedures
and safety concerns add significantly to operating
When compared to
an air magnetic circuit breaker retrofit, PowlVac®
replacement circuit breakers significantly reduce spare
parts costs and
|Powell just eliminated
obsolescence. Upgrading your outdated equipment
with PowlVac® replacement circuit breakers allows you to
take advantage of the latest in vacuum interrupter
technology for optimum reliability and performance.
Than a Retrofit
|There is no need to convert
or refurbish your existing circuit breaker. The
PowlVac® replacement circuit breaker is not a retrofit.
It is a factory designed and tested new replacement.
All of the components, including bushings are new and
designed for complete mechanical and electrical
interchangeability with your existing circuit breaker.
|Every PowlVac® replacement
circuit breaker meets or exceeds the latest ANSI
standards. Design momentary and interrupting
current tests are performed by an independent high
current test laboratory; design B.I.L. tests and
continuous current tests are performed at the Powell
laboratory in an OEM cell. Production testing
includes 300 mechanical operatons, contact resistance,
hipot, timing and vacuum integrity.
Safety interlocks inherent to
the original switchgear design (and required by ANSI)
for Direct Replacement
|PowlVac® 5kV & 15kV
replacement breakers are designed to replace existing
5kV (26 inch and 36 inch wide) and 15kV, 36 inch wide
Magneblast Type AM vertical lift air circuit breakers.
They include new frames, bushings, interlock mechanisms,
and secondary disconnects, ready for immediate
installation into your existing equipment.
Our PowlVac® DHP replacement
circuit breakers are designed with direct replacement
capability. Powell vacuum replacement circuit
breakers correctly interface with existing cell switches
(MOC & TOC).
