Medium-voltage switchgear

Pad-mounted R-VAC vacuum-break switch

Eaton's Cooper Power series RVAC pad-mounted vacuum switchgear is designed for applications where frequent 600 A main line switching plus fuse protection is required. It utilises a vacuum switch mechanism designed specifically for repetitive switching duty. Vacuum switches offer the further advantages of long life in repetitive service, low maintenance and high switching ratings.

Repetitive switching
Improved reliability
Multiple current-limiting fusing options
Easy system coordination
Compact, low-profile
Unobtrusive design

Core features

  • Available in single- or three-phase units with 15, 25 and 35 kV ratings with vacuum switches
  • Available with fuse protection (oil-filled only)
  • Removable sill
  • Oil sight gauge/SF6 pressure gauge
  • Side-opening cabinet doors
  • Pressure-relief valve for oil tanks
  • Oil fill plug/SF6 fill port
  • Stand-off brackets for each bushing
  • Removable oil fuse drip tray

Designed for optimum safety

Eaton's Cooper Power series R-VAC vacuum-break switch deadfront construction is tamper-resistant and provides a high margin of safety for utility personnel and the general public.

Ideal for use in commercial and industrial estates

Oil, E200 fluid, Envirotemp FR3 fluid or SF6 insulation provides a compact, low-profile design that is unobtrusive in commercial and industrial/business park applications.

Simplified coordination

A wide range of current-limiting fusing options provides simple, easy coordination with system requirements.
