Bussmann 170M3189 Eaton Series High-Speed Square Body Fuse, Class aR, 63A

The Bussmann 170M3189 is an Eaton series high-speed square body fuse built for demanding semiconductor protection applications. Rated 700V (UL) / 690V (IEC) at 63A with a 100 kAIC interrupting rating, this Class aR fuse meets the DIN 43 620 form factor with slotted center bolted tags for secure connections. Its aR utilization category (accompanied semiconductor protection) makes it well suited for coordinated protection of semiconductor devices in industrial power circuits.

Key Features

  • High-Speed Performance: Rated 700V (UL) / 690V (IEC) at 63A with a 100 kAIC interrupting rating for demanding semiconductor circuits.
  • Fuse Construction: Square body design with slotted center bolted tags per DIN 43 620 for secure, low-resistance connections.
  • Class aR Protection: Utilization category aR (accompanied semiconductor protection) designed to work alongside semiconductor devices rather than as sole branch-circuit protection.
  • Voltage Rating: 1250V AC voltage rating supports demanding power electronics applications.
  • I²t Coordination: Pre-arc I²t of 215 and clearing I²t of 1300 at 1000V / 1750 at 1250V for precise coordination with the semiconductor devices it protects.
  • Watt Loss: 20W watt loss rating helps engineers plan accurate thermal management in the enclosure.
  • Compact Dimensions: Measures 305 mm (length/depth) x 145 mm (width) x 65 mm (height) and weighs approximately 416.67 g.
