Bussmann FWP-100 – Frequently Asked Questions
1) Can the Bussmann FWP-100 fuse be used on a DC bus, or is it AC only?
Both. The FWP-100 carries a 700 Vac and 700 Vdc rating, so it can go into either side of a mixed installation, which is why panel builders running DC link protection and AC input protection often stock the one part instead of two.
2) Will the FWP-100 protect a semiconductor drive, or do I need a regular class fuse?
The FWP-100 is a high-speed (semiconductor) fuse, built to clear fast under fault so the diodes, SCRs and IGBTs downstream see less let-through energy than they would behind a conventional branch-circuit fuse. Use it on drives, rectifiers and power conversion gear. For general feeder and branch protection a standard time-delay class fuse is the right tool; a high-speed fuse there will nuisance open on inrush.
3) Does the Bussmann FWP-100 have a blown-fuse indicator or a microswitch option?
No. The FWP-100 is the non-indicating version, so there is no pin, flag, or indicator wiring to terminate. That makes it a drop-in for holders and bus mounts that were never prepped for indication, but if your panel relies on a microswitch for a blown-fuse alarm, this part will not trip it and you need the indicating variant instead.
4) Can I replace a 700 V high-speed fuse in an existing drive with the FWP-100?
If what came out was an FWP-series 100 amp element and your circuit is within 700 Vac/700 Vdc, the FWP-100 is the same platform and the non-indicating build drops into holders without indicator provisions. Before you swap, match the body and blade dimensions to what is in the panel, since high-speed fuse bodies vary between series even at the same amperage and voltage.
5) What size and weight is the Bussmann FWP-100 for panel layout?
Its published figures are 1.26 in height, 1.24 in length/depth, and 4.86 in width, at about .34 lb. Use the 4.86 in dimension when you are checking the span between mounting studs in the enclosure, and keep the surrounding clearance and barriers per your panel design.
6) What manufacturer part number do I order for the Bussmann 100 amp FWP fuse?
Order it as Bussmann FWP-100, from the Eaton Bussmann FWP series. That exact designation is what identifies the 700 V non-indicating high-speed fuse, and it is what your distributor or spec drawing should show.
7) Where does the Bussmann FWP-100 get used on a typical industrial job?
It shows up ahead of and inside power conversion equipment: motor drive rectifier and DC link sections, industrial control panels, and commercial or industrial installations where a fast-clearing device is required to protect solid-state components. Maintenance and MRO teams commonly hold it as a stocked spare for drive cabinets.
8) How does the Bussmann FWP-100 ship, single fuse or a carton?
It is supplied in Bussmann's standard packaging for this series, which suits stocking on a shelf or pulling for a single field replacement. Nothing about the packing changes the fuse itself.
