Bussmann 170M6198 – Frequently Asked Questions

1) Will the Bussmann 170M-619 fuse fit a standard DIN 43620 square body fuse holder?
Yes. The 170M-619 is built to DIN 43620 mounting dimensions, so it drops into holders and busbar mounts prepped for that standard. Body size is 95 mm wide, 76 mm high, and 168 mm in length/depth, with slotted center bolted tags rather than blade or clip ends, so the mounting surface needs bolt landings, not a clip base.
2) What is the difference between a Class aR and a Class gR fuse, and which do I need for a drive?
Class aR is a partial range (accompanied) semiconductor fuse: it clears short circuits and high overcurrents but is not intended to clear low level overloads on its own, so it has to be paired with another device such as the drive's electronic overload or an upstream breaker. The 170M-619 is an aR device. If you need a fuse that protects across the full range including small overloads with no backup device, that is a gR/gS full range fuse, not this one. On most rectifier and motor drive circuits the drive itself handles overload, which is why aR is the usual choice there.
3) Can I use the Bussmann 170M-619 on a DC bus?
The 170M-619 is specified as an AC fuse. DC applications need a fuse with a published DC voltage and time constant rating, because DC arcs do not self extinguish at a current zero the way AC does. Use an aR square body fuse rated specifically for DC duty instead of this one.
4) Which amp ratings does the Bussmann 170M-619 come in and what is the part number for each?
Five ratings across the family: 700A (170M6195), 800A (170M6196), 1000A (170M6198), 1100A (170M6199), and 1400A (170M6251). All share the same DIN 43620 square body envelope, so you can step ratings within the range without changing the mounting.
5) Is 100 kAIC enough for my switchgear fault current?
The 170M-619 interrupts 100 kA, which covers most industrial service entrances and drive panels. Compare it against the available fault current at the point of installation from your short circuit study, not at the utility transformer. If your calculated fault current exceeds 100 kA at that bus, this fuse is not the right device there.
6) Is the 170M-619 approved for use in equipment being shipped to Europe?
It is CE Marked, so it can be used in equipment declared to the applicable EU directives. That is the compliance mark carried on this fuse; if a project spec calls out a UL or CSA listing specifically, verify that separately against the rating on the device you receive.
7) What kind of terminations does the 170M-619 use, and what do I need to land it?
Termination is by slotted, center bolted tags, so it lands on bolted busbar or bolt down fuse bases with hardware sized to the tag slots. There are no gripping lugs on the body, meaning you handle and remove it by the tags, so allow tool clearance around the 95 by 76 mm face when laying out the enclosure.
8) Does the Bussmann 170M-619 have a blown fuse indicator or a microswitch?
Indicator style on the 170M-619 is listed as other, and it is supplied without insulated metal gripping lugs. If your panel relies on a microswitch striker feeding a fault relay, confirm the exact indicator variant you need before ordering, because the striker option changes the part number within the 170M range.
