The S3C is a low profile, reduced phase-to-phase distance double side disconnector that provides additional space savings. The optimum mechanical and electrical characteristics of the current carrying parts are ensured through the use of high strength aluminium alloys combined with silver-plated copper contacts. The S3C can be customized for vertical, underhung and phase-over-phase installations.

Customer Benefits
 
  • Minimum phase-to-phase spacing
  • Small enter-to-center distance between poles
  • Reduced phase-to-phase distance
  • Built-in earthing switches and arc restrictors available
  • Virtually maintenance free
  • Easy start-up and commissioning
