New Cooper Power Systems Edison™ Capacitor Switch Increases Overall
System Reliability and Reduces Lineman Time in the Field
Robust Operational and Bushing Designs, and Unique Terminal Ring, Provide
Dependability and Ease of Use
WAUKESHA, WI, June 11, 2013 — Simplify capacitor switching while increasing system reliability
with the new easy-to-use Cooper Power Systems Edison™ capacitor switch. Utilizing a direct
drive, permanent magnet solenoid and dual coil design, the switch eliminates the need for cams,
linkages, struts, or electronic circuit boards or relays reducing the potential for electrical failure. The
heart of the switch is the field-proven Eaton vacuum interrupter specifically designed for capacitor
switching. To ensure long life in the harshest environmental conditions, the vacuum bottle is
encapsulated in a rugged cycloaliphatic epoxy bushing that offers superior hydrophobic properties.
The alternating bushing shed design provides effective self-cleaning to improve flashover
performance over porcelain bushings.
“Our new Edison capacitor switch has a revolutionary modular terminal ring design, which allows
for 360-degree termination of load – in 60-degree increments. This eliminates the need to rotate
the switch body to accommodate installation,” said Pat Bowers, global product manager,
capacitors, Cooper Power Systems. “This not only increases reliability by eliminating the need to
remove the head and break seals, but allows for multiple terminals or additional loads by simply
adding another terminal clamp.”
The Edison capacitor switch can also be used with any industry standard capacitor controller such
as the Cooper Power Systems CBC-8000 capacitor bank control to provide Integrated Volt/VAR
Control (IVVC), leading to overall cost savings for utilities.
The product’s non-metal tank design is constructed of fiberglass reinforced polyester to prevent
corrosion, and has an integrated rain shield and hotstick guide for the trip handle. The standard

manual trip handle provides easy hotstick operation, a visual trip indicator and allows quick
verification of switch state.
Applications for the new Edison capacitor switch include distribution capacitor switching, IVVC/
Conservation Voltage Reduction (CVR), capacitor racks, metal enclosed capacitor banks and
outdoor distribution substation banks.
