Bussmann 170M2710 High-Speed Square Body Fuse, Class aR, 40A, 700V

The Bussmann 170M2710 is an Eaton series high-speed square body fuse engineered for semiconductor protection in demanding industrial power electronics applications. Rated 700V (UL) / 690V (IEC) and 40A with a 200 kAIC interrupting rating, this Class aR fuse uses blade end x blade end contacts and conforms to the DIN 43 620 mounting standard for square body fuses. A top-mounted fuse status indicator provides fast visual confirmation of fuse condition, helping maintenance teams verify circuit protection status without powering down equipment.

Key Features

  • Square Body Dimensions: Measures 75 mm (length/depth) x 163 mm (width) x 77 mm (height) and weighs 211 g, per the DIN 43 620 square body footprint.
  • Dual Voltage Rating: Rated 700V (UL) and 690V (IEC), AC voltage type, for use across both UL and IEC-governed installations.
  • 40A Current Rating: Delivers reliable overcurrent protection at 40 A for connected semiconductor loads.
  • 200 kAIC Interrupting Rating: High interrupting capacity supports demanding fault-current environments.
  • Class aR Utilization Category: Designed as an accompanied semiconductor protection fuse (aR), for use alongside other overcurrent devices rather than as stand-alone branch protection.
  • Blade End x Blade End Contacts: Flush-end blade contacts on a square body fuse shape simplify mounting in compatible fuse holders.
  • Top Fuse Status Indicator: Built-in top indicator allows quick visual verification of fuse condition.
  • Low Watt Loss: Rated at 9 W watt loss, with a pre-arc I2t of 50 and clearing I2t of 360 at 660V for predictable let-through performance.
