Edison Capacitor Switch

Edison_23050_220.jpg

Eaton's Cooper Power™ series single-phase Edison™ capacitor switch line is ideal for the difficult capacitive current switching duty of distribution capacitor banks. The Edison family includes 15 kV and 25 kV class switches that are available for system applications up to 38 kV. This solid dielectric vacuum switch with unique, permanent magnetic solenoid mechanism has been designed in accordance with IEEE Std 37.66™-2005 standard.

Catalog Number ECS15-95, ECS15-125, ECS25-125, ECS25-150
Compliance Edison switches are designed and tested in accordance with IEEE Std C37.66™-2005 standard.
Operating Voltage Range, 50/60 Hz 110 to 240 V ac

Features

Vacuum Bottle

  • Field-proven Eaton™ vacuum interrupter
  • Specifically designed for capacitor switching
  • Fully encapsulated in solid dielectric material for effective heat transfer and maintenance-free operation

Revolutionary Terminal Ring Design

  • Allows for 360 degree termination of load (in 60 degree increments)
  • Eliminates need to break seals for rotation of the switch body to accommodate installation requirements
  • Allows for multiple terminals by simply adding another terminal clamp

Cycloaliphatic Epoxy Bushings

  • High creep versus porcelain for improved performance in contaminated environments
  • Highly resistant to ozone, moisture, contamination, and ultra-violet light
  • Less surface wetting
  • Alternating shed design improves flashover performance
  • Bushing shed designed per IEC 60815

Permanent Magnetic Solenoid

  • Direct drive, permanent magnet solenoid design with no cams, linkages, or struts needed
  • Dual coil design eliminates the need for relays or circuit boards to open and close the switch
  • Solenoid operates in voltage range of 75 V to 130 V (120 Vac option)
  • Critical opening operation powered by a heavy duty precision spring which provides consistent opening speeds that are effectively immune to variations in ambient temperature

Non-metal Tank Design

  • Fiberglass reinforced polyester prevents corrosion; same material as boat hulls
  • Integrated rain shield and hotstick guide for trip handle

Standard Manual Trip Handle

  • Easy hotstick operation
  • Visual trip indicator to quickly see state of switch
  • Designed for manual open only for increased safety
