Bussmann FWP-90 – Frequently Asked Questions

1) Can the Bussmann FWP-90 fuse be used on a DC circuit, or is it AC only?
The FWP-90 carries a single 250 Vac/dc rating, so it covers both AC and DC circuits up to 250 volts. That is why it shows up in rectifier and motor drive work, where the same fuse may sit on the AC line side or on the DC bus. Do not apply it above 250 volts on either system.
2) What does a high-speed fuse like the FWP-90 protect that a regular time-delay fuse won't?
High-speed (semiconductor) fuses clear fault current much faster than general-purpose or time-delay fuses, which is what keeps diodes, SCRs and IGBTs from failing before the fuse opens. The FWP-90 is built for that duty: power electronics and semiconductor protection, rectifier and drive circuits, switchgear and DC distribution. If you are protecting a motor with inrush and no solid-state devices in the path, a time-delay class fuse is the better fit; a high-speed fuse may open on normal starting surge.
3) Is the FWP-90 an indicating fuse? I need to see at a glance which one blew.
No. The FWP-90 is the Standard, Non-Indicating configuration, so there is no blown-fuse window or pop-up pin. To find the open fuse you meter it or pull it. If visual trip status matters in your panel, you need an indicating version of the FWP series rather than this one.
4) What are the dimensions and weight of the Bussmann FWP-90 so I can check it fits my fuse block?
Published figures are 1.26 in height, 1.24 in length/depth, 4.86 in width, and about .34 lb. The 4.86 in figure is the long axis, so allow that much clear run between the block terminals plus room for the mounting bolts before you commit to the enclosure layout.
5) What approvals does the Bussmann FWP-90 hold for a spec-driven job?
For approvals on the FWP-90, Eaton directs enquiries to the factory, so confirm the certification list against your submittal before you specify it. What is published is the electrical rating: 250 Vac/dc, high-speed, non-indicating.
6) Does the Bussmann FWP-90 come as a single fuse or in a multi-pack?
Packaging is listed as Standard for the FWP-90, the ordinary single-fuse commercial pack rather than a bulk or multi-pack configuration. Panel builders stocking spares order by quantity rather than by pack.
