Bussmann 170M3741 Class aR Square Body Fuse, 100A 1000V

The Bussmann 170M3741 is a Class aR square body semiconductor fuse rated 100A and 1000V, engineered to protect solid-state power devices in demanding DC applications. Built in the US-style square body configuration with an -FKE/115 type body, this fuse delivers a 100 kAIC interrupt rating for high fault-current protection on DC common bus systems, DC drives, power converters/rectifiers, and reduced voltage starters. It is CSA Certified and CE Marked, giving specifiers a documented, code-compliant option for critical power protection.

Key Features

  • Amperage Rating: 100A for dependable overcurrent protection in DC power circuits.
  • Voltage Rating: Rated 1000V, with clearing I²t data documented at both 1000V and 1250V for demanding DC bus coordination.
  • Class aR Design: Semiconductor-protection fuse class purpose-built for power converters, rectifiers, and DC drives.
  • Interrupt Rating: 100 kAIC interrupt rating supports high fault-current environments.
  • Fuse Indicator: Non-indicating element construction.
  • Square Body Construction: US-style square body, -FKE/115 type body configuration.
  • I²t Characteristics: Pre-arc I²t of 750 and clearing I²t of 4450 at 1000V / 5950 at 1250V for precise system coordination.
  • Watt Loss: 30W watt-loss rating for accurate thermal and panel-design planning.
