Bussmann 170M3014 Eaton Series High-Speed Square Body Fuse, Class aR

The Bussmann 170M3014 is an Eaton series high-speed square body fuse engineered for demanding semiconductor protection duty, rated 700V (UL) / 690V (IEC) at 160A with a 200 kAIC interrupt rating. Built to DIN 43 620 dimensional standards with blade end x blade end terminals, this Class aR fuse is designed to guard power semiconductors in industrial drives and power conversion equipment. A top fuse status indicator provides fast visual confirmation of fuse condition during inspection and maintenance.

Key Features

  • Compact Dimensions: Square body measuring 305 mm length, 145 mm width, and 65 mm height for standard high-speed fuse mounting.
  • Blade End x Blade End Connection: Slotted, center-bolted square body tags for secure, low-resistance terminal contact.
  • Electrical Rating: 700V (UL) / 690V (IEC), 160A, 200 kAIC interrupt rating for robust fault current protection.
  • Class aR Utilization: Accompanied semiconductor protection category purpose-built for safeguarding power semiconductor devices.
  • Top Fuse Status Indicator: Enables quick visual verification of fuse condition without removal.
  • I2t Performance: Pre-arc I2t of 1100 A²s and clearing I2t of 7500 A²s at 660V for predictable current-limiting response.
  • AC Voltage Type: Rated for AC systems in industrial power distribution and drive applications.

Bussmann 170M3014 – Frequently Asked Questions

1) Will the Bussmann 170M3014 fit my existing square body fuse holder?
The 170M3014 is built to DIN 43 620 dimensional standards with a square body and slotted, center-bolted tags, so it drops into holders and busbar mounts prepped for that standard. Connection is blade end x blade end. Body measures 305 mm, 145 mm, and 65 mm as length, width, and height. It does not have insulated metal gripping lugs, so if your assembly relies on IMGL-style gripping, this is not the version to order.
2) Can I use a Class aR high-speed fuse as the branch circuit or overload protection for a motor?
No. Class aR is an accompanied semiconductor protection category, meaning it only covers the short circuit end of the range and must be used alongside another protective device for overload. The 170M3014 is meant to protect power semiconductors in drives, rectifiers, and power conversion gear. For overload and general branch circuit duty you still need the breaker or overload relay the drive manufacturer specifies.
3) What voltage and current is the Bussmann 170M3014 rated for, and does it cover both UL and IEC systems?
Rated 160 A, 700 V under UL and 690 V under IEC, AC only. Interrupting rating is 200 kAIC. It is UL Recognized and CE Marked, so it can be specified on equipment built to either UL or IEC rules. There is no DC rating stated for it, so do not apply it on a DC link without a DC-rated part.
4) What I2t values do I need to coordinate this fuse with my SCRs or diodes?
Pre-arc I2t is 1100 A2s and total clearing I2t is 7500 A2s at 660 V. Compare the clearing figure against the I2t withstand of the semiconductor you are protecting: the device rating has to be higher than 7500 A2s at your working voltage, or the fuse will not clear before the junction does. Clearing loss is listed at 30.
5) How can a maintenance tech tell if a 170M3014 has blown without pulling it out of the holder?
It carries a top-mounted fuse status indicator, so a tech can confirm condition visually during a panel inspection with the fuse still bolted in place. Useful on multi-fuse rectifier banks where pulling each element to test would mean an extended outage. Note the indicator is on the top face, so it needs to be visible from the front or above once mounted.
6) Is the Bussmann 170M3014 the right part number to order as a direct replacement in a drive panel?
The manufacturer part number is 170M3014, sold as a single fuse in standard packaging. When replacing an existing element, match the printed number on the old fuse exactly. A 170M part with a different suffix can differ in body size, tag style, or indicator, and those changes affect whether it bolts into the same holder.
7) How much does a 170M3014 square body fuse weigh for panel and shipping planning?
About 352 g per fuse. With a 305 mm body length it is a substantial element, so on a bank of several fuses account for the mounting support and the stud torque the holder manufacturer calls for rather than hanging them off the busbar alone.
