Bussmann FWP-40 – Frequently Asked Questions

1) Will the Bussmann FWP-40 fuse fit my existing fuse holder or clip block?
The FWP-40 body measures 4.35 in. high with a .75 in. width and .75 in. depth, so check that against the clip spacing and cavity in your holder before ordering. It's a standard, non-indicating body, meaning there's no indicator pin or micro-switch striker protruding, so it drops straight into holders built for a plain high speed fuse.
2) What is a high speed fuse like the Bussmann FWP-40 used for, and when should I use a standard fuse instead?
High speed (semiconductor) fuses like the FWP series are built to clear an overcurrent fast enough to protect silicon, so they belong on power electronics, motor drives, rectifier circuits and industrial power conversion gear. A standard time-delay or general purpose fuse is the right choice on motor branch circuits and feeders where inrush has to be ridden through, because a high speed fuse will nuisance-open on that inrush. Match the fuse to the device you're actually protecting.
3) Can the Bussmann FWP-40 be used on a DC bus, or is it AC only?
Both. The FWP series carries a 1000 Vdc rating (FWL/FWS 2-30 A) alongside AC ratings of 1400 Vac (FWS 8-15 A) and 2100 Vac (FWS 2-6 A), so it is applied on DC links as well as AC circuits. Apply whichever rating line matches your circuit, and never exceed the DC rating on a DC bus even if the AC number looks higher.
4) Does the Bussmann FWP-40 have a blown fuse indicator or microswitch option?
No. The FWP-40 is the non-indicating version, with no visual indicator pin and no provision for a microswitch. If your panel relies on a blown-fuse alarm or a trip signal back to the controller, you need an indicating version of the fuse plus the matching microswitch, not this one.
5) What part number do I order for this Bussmann high speed fuse?
Order it as Bussmann FWP-40, manufactured under Eaton's Bussmann series. That catalog number is the manufacturer part number, so it's what a distributor or MRO storeroom should be cross-referencing when standardizing spares. It ships as standard packaging.
6) Is the Bussmann FWP-40 UL listed or IEC certified?
Compliance for the FWP-40 is listed as contact factory, so approvals should be confirmed with Eaton for your specific application rather than assumed from the series. If your spec requires a named listing on the drawing, get that confirmation in writing before you install.
7) How heavy is the Bussmann FWP-40 fuse for stocking and shipping?
About .18 lb each. That's light enough that a storeroom can carry several spares on a shelf without any special handling, which matters when you're keeping a critical drive or rectifier back online quickly.
