HVL Metal-Enclosed Load Interrupter Switchgear

Reliable solution for load break switch applications in the medium voltage range.

The Square D® HVL interrupter switchgear offers a reliable solution for load break switch applications in the medium voltage range.

The ANSI rated switchgear is available for various applications and configurations up to 1200A, including:

  • Individual service entrance bays
  • Multiple-bay lineups for main and feeder switches
  • Unit substation primaries
  • Multiple bay feeder lineups incorporated with Metal-Clad or Visi-Vac® switchgear
  • Indoor or outdoor applications
  • Switch momentary ratings up to 80kA Asymmetrical
  • UL Listed switchgear
Exclusive Performance Features
  • Fuselogic™ for single phase protection of three phase loads
  • Fuselogic for blown fuse indication and switch lock out feature
  • Electrically operated switches with remote open, close, and charge functionality
  • Stored energy mechanism with shunt trip capabilities meeting NEC Article 710
  • High track resistant insulators throughout switchgear (3 times the tracking resistance than traditional glass polyester insulators)
