Bussmann 170M5365 Eaton Series Class aR Square Body Fuse, 900A, 700V

The Bussmann 170M5365 is an Eaton Bussmann series high-speed square body fuse engineered for semiconductor protection in demanding AC power applications. Rated 700V (UL) and 690V (IEC) with a 900A amperage rating and a 200 kAIC interrupt rating, this Class aR fuse is built to accompany semiconductor devices rather than provide stand-alone protection, delivering fast, reliable current-limiting performance. The square body design features slotted, center bolted tags for straightforward busbar mounting in industrial power electronics installations.

Key Features

  • Compact Square Body Design: Measures 286 mm in length/depth, 165 mm in width, and 66 mm in height, with slotted center bolted tags for secure busbar connections.
  • High-Speed Class aR Rating: Utilization category aR (accompanied semiconductor protection) delivers rapid current-limiting response for semiconductor protection duty.
  • Dual Voltage Rating: Rated 700V under UL and 690V under IEC, supporting AC voltage systems across both North American and international standards.
  • 900A Amperage Rating: Sized for high-current industrial circuits requiring dependable semiconductor protection.
  • 200 kAIC Interrupt Rating: High interrupting capacity supports use in demanding industrial power distribution systems.
  • Documented Let-Through Performance: Pre-arc I2t of 125000 and clearing I2t of 840000 at 660V give engineers the data needed for accurate coordination studies.
  • Watt Loss Rating: Rated at 110W watt loss for thermal design and enclosure planning.
