SF6 - Sectionalizer



General Information :


Gas Insulated Sectionalizer with magnetic actuator operated mechanism with built in CT, PT or current/voltage sensors is suitable for structure as well as pole mounted execution for urban and rural electrification application.

 Applicable standards

Complies with IEC 62271-111/ ANSI C37.60.

  • Suitable for four shot auto reclosing duty
  • Ideally suitable for transient fault application
  • Suitable for pole by pole tripping & closing
Product Features
  • Guaranteed for 1,00,000 mechanical operations
  • Made from Marine Grade Stainless Steel
  • State of the art magnetic actuator mechanism
  • Self powered hence no external auxiliary supply is required
  • Manual tripping available by hook stick
  • Positively driven mechanism status indication for breaker condition (ON/OFF), visible from ground
  • Ensures long life & reliability under extreme environmental conditions
  • Solid insulation, UV resistant
  • Special grade Stainlesss Steel Tank robotically welded giving maximum outdoor IP protection (IP:55 for switching Unit and IP:65 for control cabinet)
  • RTU can be supplied for control & monitoring the status of recloser, the relay timer setting & metering parameters and can be made to communicate at control room through GSM/CDMA network. Thus suitable for remote operations. SCADA compatible
  • Light weight
  • Self powered
  • SCADA compatible
