FLSR series fuses provide excellent protection for all types of circuits especially those containing motors. However, users and specifiers should consider the significant benefits offered by Indicator fuses.

Applications:

  • Service entrance switches
  • Transformers
  • Switchboard main and feeder switches
  • Motor control center mains and motor branch circuits
  • Individual fused combination motor controllers
  • Distribution panelboards
  • Industrial control panels
  • Protection of fully-rated panelboards and loadcenters
  • All general purpose circuits

Safety:

  • 200,000 A.I.R.- Reliable interruption of all overcurrents up to 200,000 amperes.
  • Faster acting short circuit protection than any non-current limiting mechanical protective device.

Reliability:

  • Accurate and reliable - Automated, precision manufactured and assembled parts ensure accurate, consistent response to overloads and short circuits.
