Bussmann 170M6108 – Frequently Asked Questions

1) Will a Bussmann 170M-610 fuse fit my existing square body fuse holder or bus bar mounting?
The 170M-610 is built to the DIN 43620 dimensional standard with a blade end x blade end connection, so it bolts into DIN 43620 size-3 style mounting used by square body holders and bus bar arrangements. Body dimensions are 95 mm width, 76 mm height and 168 mm length/depth. If your existing mounting centers are set for a different DIN body size, the blades will not line up.
2) What amp ratings does the Bussmann 170M-610 come in, and what part number do I order?
Four ratings: 500A (170M6108), 550A (170M6109), 630A (170M6110) and 700A (170M6111). All four share the same 690V rating, square body footprint and DIN 43620 mounting, so you can step the amp rating up or down without changing the holder.
3) Can I use a Class aR fuse like the 170M-610 as the only protection for a drive circuit?
No. Class aR is an accompanied semiconductor protection category, meaning it protects the semiconductors against short circuit but is not a full-range device on its own. It has to work alongside upstream overload protection such as the drive's electronic overload or a separate branch circuit device. If you need a fuse that covers overload and short circuit through the full range, you want a gR/gS type instead.
4) Is the 170M-610 UL Listed or UL Recognized, and is it CE marked?
It is UL Recognized, not UL Listed, and it is CE marked. UL Recognized means it is approved as a component within a larger listed assembly such as a drive or switchgear panel, which is how these high-speed fuses are normally applied. If your inspector is asking for a standalone UL Listed device, this is not that.
5) Is the Bussmann 170M-610 rated for 480V or 600V industrial systems?
It is a 690V AC device, so it covers 480V and 600V AC systems within its rating. It is an AC rating only, so do not apply it to a DC link or battery circuit on the basis of this number.
6) What fault current can the 170M-610 interrupt?
200 kAIC. That covers high available fault current at service entrance and large drive installations, which is why this fuse gets specified ahead of rectifier bridges and IGBT stacks where a slower device would let the semiconductor fail first.
7) Does the Bussmann 170M-610 come with insulated gripping lugs for hot handling?
No, the 170M-610 does not have insulated metal gripping lugs. It uses slotted center bolted tags, so it is pulled and installed with the circuit de-energized and a wrench, not by hand. If your maintenance procedure depends on IMGL handles, specify a version that carries them.
8) Can I swap a 500A 170M6108 for a 700A 170M6111 in the same holder?
Mechanically yes, since all four ratings in the 170M-610 family share the 95 x 76 x 168 mm square body and the same DIN 43620 blade mounting. Electrically it is a different decision: moving from 500A to 700A raises the let-through energy the fuse allows, so the semiconductor it protects has to be sized for it. Match the rating to the device manufacturer's recommendation, not to the holder.
9) What kind of equipment is the Bussmann 170M-610 normally installed in?
Semiconductor protection is the stated application: rectifier and motor drive circuits, industrial power distribution, and switchgear or panelboard builds where fast clearing of a fault is what keeps the power electronics alive. It is a bolt-in square body device, so it lives inside an enclosure on bus work rather than in a plug-in disconnect.
