Bussmann 170M6117 – Frequently Asked Questions

1) Will the Bussmann 170M6117 fuse fit a DIN 43 620 size 3 square body holder?
The 170M6117 is built to DIN 43 620 mounting dimensions with blade end x blade end slotted offset bolted tags. Its body measures 138 mm long, 58 mm wide and 45 mm high, so check those against the centre spacing and clearance in your existing bus bar or fuse base before ordering. It bolts down rather than clipping in, and it does not have insulated metal gripping lugs.
2) Can I use a Class aR semiconductor fuse for branch circuit or cable protection?
No. Class aR is accompanied semiconductor protection, meaning the 170M6117 only protects against short circuit and high fault current and must be backed up by another device for overload protection. If you need full-range protection of a circuit on its own, you want a gR/gS type fuse or a conventional branch circuit fuse instead. An aR fuse in that role will not clear low-level overloads.
3) What voltage system can the Bussmann 170M6117 be applied on?
It is an AC fuse rated 700V under UL and 690V under IEC, so it suits 690V class industrial drive and rectifier circuits. Don't apply it above those figures, and don't assume a DC rating from them, since the published rating here is AC only.
4) Will a 1400A high-speed fuse protect the IGBTs or SCRs in my drive?
Coordination comes down to I2t, not just amps. The 170M6117 carries a pre-arc I2t of 370000 and a clearing I2t of 2450000 at 660 V, with a clearing loss figure of 155. Compare the clearing I2t against the withstand I2t published for your SCR or diode module at the working voltage. If the semiconductor's rating is lower than the fuse's let-through, the device blows before the fuse does and you need a smaller amp rating.
5) Is the 170M6117 UL Listed or UL Recognized, and does it carry a CE mark?
UL Recognized, not UL Listed, and it is CE Marked. Recognized means it is approved as a component for use inside a larger assembly such as a drive cabinet or OEM power electronics build, rather than as a standalone listed device. If your specification calls out UL Listed fuses specifically, this one will not satisfy it.
6) What do I need to mount a 170M6117 square body fuse, and how heavy is it?
Mounting hardware and the fuse base are not part of the fuse itself. The 170M6117 has bolted blade tags, so you supply the bolts, washers and torque per your base or bus bar arrangement. At 912 g it is heavy enough that both tags need proper bolted support, not a single-point mount.
7) Does the Bussmann 170M6117 have a microswitch or striker indicator for remote blown-fuse signalling?
The indicator on the 170M6117 is listed as Other, so it is not a standard microswitch or striker version. If your panel needs a blown fuse contact wired back to the control system, specify a 170M part number built with the indicator and microswitch option rather than relying on this one.
8) Where are Bussmann 170M series high-speed fuses typically used?
Semiconductor protection is the job: rectifier stacks, variable frequency drives, soft starters, UPS systems and OEM power electronics assemblies in industrial distribution. Maintenance teams keep the exact amp and voltage match on the shelf because a drive down for a blown fuse is not something you substitute your way out of. Match 170M6117 exactly to what came out.
