Bussmann 170M5117 – Frequently Asked Questions

1) Will the Bussmann 170M-511 square body fuse fit my existing DIN 43 620 fuse holder or busbar mount?
Mounting is to the DIN 43 620 standard, so it drops into panel and busbar arrangements built to that dimensional spec. Body size is 165 mm wide, 66 mm high and 286 mm long/deep, with blade end to blade end connections using slotted center bolted tags. Check your bolt-hole centers against the tags before you pull the old fuse.
2) What amp ratings can I order in the Bussmann 170M-511 high-speed fuse?
The 170M-511 family covers 400A through 1250A. Orderable ratings are 400A (170M5258), 450A (170M5259), 500A (170M5260), 900A (170M5115), 1100A (170M5117) and 1250A (170M5118). Match the rating to the semiconductor load you are protecting, not to the feeder breaker.
3) Is a Class aR fuse the right choice, or do I need a gR type?
Class aR is a partial-range device: it clears short circuits only and has to work alongside an upstream overcurrent device that handles overloads. That is exactly how the 170M-511 is built, under the aR utilization category for accompanied semiconductor protection. If your drive or rectifier has no separate overload protection, you want a full-range gR/gS type instead.
4) Can I use the 170M-511 on a 1000V AC drive system?
Yes. It is an AC-rated fuse carrying 1250V under IEC and 1300V under UL, so a 1000V AC system sits inside both ratings. Do not apply it on DC circuits, the published rating is AC only.
5) What short-circuit current rating does the Bussmann 170M series square body fuse carry?
200 kAIC. That covers the available fault current at most industrial service entrances and drive lineups, which is why these get specified ahead of rectifier stacks and IGBT bridges rather than a general-purpose fuse.
6) Does the 170M-511 fuse come with insulated metal gripping lugs for hot-swapping?
No. The 170M-511 is supplied without IMGL. Connection is plain blade end to blade end with bolted tags, so the panel must be de-energized and locked out before removing or fitting the fuse.
7) Is the Bussmann 170M-511 acceptable for equipment we export to Europe?
It is CE Marked and manufactured to the DIN 43620 dimensional standard, with a dual IEC/UL voltage rating of 1250V/1300V, so it suits panels built for both European and North American markets.
8) How do I make sure I order the right 170M fuse when I only know the amp rating?
Order by the specific part number, not by the series alone. Each amp rating in the 170M-511 range is its own number: 170M5258, 170M5259 and 170M5260 for 400A, 450A and 500A, then 170M5115, 170M5117 and 170M5118 for 900A, 1100A and 1250A. All share the same square body, blade end connections and DIN 43 620 mounting, so only the element rating changes.
