Bussmann 170M3017 Eaton Series High Speed Square Body Fuse, 315A, Class aR

The Bussmann 170M3017 is an Eaton Bussmann series high speed square body fuse engineered for semiconductor protection, rated 700V (UL) / 690V (IEC) with a 315A rating and a 200 kAIC interrupting capacity. Built to DIN 43 620 with blade end x blade end terminations and a Class aR (accompanied semiconductor protection) utilization category, this fuse features a top-mounted fuse status indicator for quick visual verification of fuse condition in industrial power electronics equipment.

Key Features

  • Dual Voltage Rating: 700V (UL) and 690V (IEC) rating supports both North American and international installations.
  • Amperage Rating: 315A high speed rating sized for demanding semiconductor protection circuits.
  • Interrupting Rating: 200 kAIC interrupting capacity for high fault-current industrial applications.
  • Fuse Shape: Square body construction with slotted, center bolted tags, blade end x blade end, built to DIN 43 620.
  • Utilization Category: Class aR (accompanied semiconductor protection) for coordinated semiconductor device protection.
  • Fuse Status Indicator: Top-mounted indicator provides a quick visual check of fuse condition.
  • Clearing / Pre-Arc I²t: Clearing I²t of 46500 at 660V and Pre-Arc I²t of 7000 for reliable coordination with semiconductor devices.

Bussmann 170M3017 – Frequently Asked Questions

1) Will a Bussmann 170M3017 fuse mount in my existing square body fuse holder?
The 170M3017 is a square body fuse with slotted, center bolted tags and blade end x blade end terminations, built to the DIN 43 620 mounting standard. If your holder or busbar is drilled for DIN 43 620 blade-type square body fuses, it bolts straight in. Overall size is 305 mm x 145 mm x 65 mm, so confirm you have that envelope inside the enclosure before ordering.
2) Is a Class aR fuse the right choice to protect my drive's semiconductors, or do I need gR/gS?
Class aR is partial-range, or accompanied, semiconductor protection: it handles short-circuit faults only and must work alongside another device (typically the drive's own overload protection or an upstream breaker) for overload duty. The 170M3017 is an aR fuse, so it is not a standalone protector. If you need a single fuse to cover both overload and short circuit on the same branch, you want a full-range gR or gS type instead.
3) Can I use the 170M3017 on a 600V or 690V AC industrial system?
Yes. The 170M3017 carries a 700V UL rating and a 690V IEC rating, AC, which covers 480V and 600V North American systems as well as 690V European drives. It is an AC-rated fuse, so do not apply it as a DC-rated device on a DC link without the manufacturer's DC data.
4) What I2t values do I need to coordinate this fuse with my SCR or diode module?
Coordination data for the 170M3017: clearing I2t of 46500 at 660 V and pre-arc I2t of 7000. Compare the clearing figure against the I2t withstand of the SCR or diode you are protecting; the device rating must exceed the fuse's clearing I2t at your system voltage. Clearing loss is listed at 50.
5) What fault current can this 315A Bussmann fuse safely interrupt?
Interrupting rating is 200 kAIC at its rated voltage, which covers most high fault-current industrial services fed from large transformers. Continuous rating is 315 A.
6) Can a technician tell if this fuse has blown without pulling it out?
Yes. A top-mounted fuse status indicator lets maintenance confirm fuse condition visually with the fuse in place, which is useful on multi-fuse banks where pulling and ohming each one costs downtime.
7) Does the 170M3017 come with insulated metal gripping lugs for hot insertion?
No. This one is supplied without insulated metal gripping lugs (IMGL). If your maintenance procedure calls for gripping-lug removal, you need the IMGL variant of the 170M series rather than this part number.
8) Is this fuse acceptable for a CE-marked machine build going overseas?
The 170M3017 is IEC rated and CE marked, and it is built to DIN 43 620, so it suits machinery documentation for European installations as well as North American panels under its 700V UL rating.
