Bussmann 170M2700 – Frequently Asked Questions

1) Will the Bussmann 170M-269 fuse fit a standard square body fuse holder?
The 170M-269 uses blade end terminals made to DIN 43 620, so it mounts in high speed square body holders and bolt-down bases built to that same DIN blade standard. It is not a ferrule or clip-in cartridge fuse, and it does not come with insulated metal gripping lugs (IMGL), so if your base requires the lug style you need the IMGL version instead.
2) Can I use a gR fuse like the 170M-269 for general circuit and cable protection, or only for semiconductors?
gR is the dual-duty class. The 170M-269 is rated gR, meaning general purpose semiconductor protection: it clears the low overload range as well as short circuits, so it protects the cable and the equipment in addition to the diodes or thyristors. An aR fuse, by contrast, is back-up only and has to be paired with a separate overload device. If your drive or converter branch has no other overload protection, gR is the one you want.
3) Is the Bussmann 170M-269 rated for a 690V IEC panel or a 700V UL system?
Both. The 170M-269 carries a 700V rating under UL and 690V under IEC, on AC only. There is no DC rating stated for it, so do not apply it to a DC link or battery circuit on the strength of the AC number.
4) What short circuit current can the 170M-269 fuse interrupt?
200 kAIC. That covers the available fault current at most industrial service and drive panels, which is the reason high speed square body fuses get specified ahead of breakers on semiconductor branches, they clear the fault in well under a half cycle and limit the let-through energy the silicon sees.
5) How do I tell if a 170M-269 fuse has blown without pulling it out of the holder?
Each one has a top-mounted fuse status indicator, so a tech can walk the panel and confirm fuse condition visually with the fuse still in place. Worth knowing when you spec the enclosure: the indicator faces up, so leave access above the fuse base rather than burying it behind a barrier. Some versions of this style also accept a microswitch on the indicator for remote signalling, but that is a separate ordering option, not part of the standard top indicator.
6) Does the Bussmann 170M-269 fuse carry CE marking for a European machine build?
Yes, the 170M-269 is CE marked, which is what an OEM panel builder needs on the documentation package for a machine shipping into the EU. Its IEC rating for that market is 690V AC.
7) How do I order the right 170M-269 fuse, is the part number different per amp rating?
Yes, you order by the individual part number, not by the 170M-269 series reference. Common ones: 170M2693 is 20A, 170M2696 is 40A, 170M2698 is 63A, 170M2700 is 100A and 170M2702 is 160A. They ship in standard packaging. The class, voltage, blade style and 200 kAIC rating are the same across the whole run, only the amp rating and body size change with the number.
8) What is the 170M-269 typically used on in an industrial plant?
Semiconductor protection duty: VFD and motor drive input or output sections, rectifier and converter stacks, power electronics assemblies, and high speed fuse panels in industrial and commercial installations. Anywhere the thing being protected is a diode, SCR or IGBT rather than a motor winding, a standard Class J or RK5 fuse is too slow and this is the type that gets specified.
