Bussmann FWP-175 – Frequently Asked Questions

1) Can the Bussmann FWP-175 fuse be used on a DC bus, or is it AC only?
Both. The FWP-175 carries dual ratings: 700 Vac under UL, 690 Vac under IEC, and 800 Vdc. That DC rating is what makes it usable on drive DC links and rectifier/inverter buses, not just AC line side.
2) What kind of fuse is the Bussmann FWP-175 and what is it meant to protect?
It's a high-speed (semiconductor) fuse from the Eaton Bussmann FWP series, built to clear fast enough to protect solid-state devices: diodes, SCRs, IGBT power stages, rectifiers, drives and power conversion equipment. It is not a general-purpose branch circuit fuse for lighting or motor feeders.
3) Is the FWP-175 the right choice for a 480V or 600V industrial control panel?
Yes on voltage headroom. With a 700 Vac UL rating it covers 480 V and 600 V AC systems, and a fuse may always be applied at or below its voltage rating. What it will not do is replace a standard time-delay class fuse on a motor branch circuit, since the FWP is a high-speed semiconductor fuse and clears too quickly to ride through motor inrush.
4) Will the FWP-175 give me a blown-fuse signal for remote monitoring?
No. The FWP-175 is a non-indicating body, so there is no pop-up pin or microswitch provision. If your panel needs blown-fuse annunciation, you'll need an indicating version of the fuse or a separate external indicator/monitoring relay across the fuse.
5) How much space do I need in the panel for the FWP-175 fuse?
Allow for a body measuring 5.9 x 5.9 x 1.25 inches (height x length/depth x width). At 1.25 inches wide it suits tight multi-pole stacks, but the 5.9 inch dimensions mean you want to check depth behind the mounting pan before you commit the layout.
6) What exact part number do I order for the Bussmann 175 amp high-speed fuse?
Order by MPN FWP-175, Bussmann by Eaton, FWP series. The 175 in the designation is the amp rating; the rest of the FWP line follows the same pattern, so keep the full suffix when you quote it to avoid getting a different amperage.
7) How does the FWP-175 ship, and is it a single fuse or a pack?
Packaging is Standard, and the item is the single FWP-175 fuse. If you're fusing a three-phase rectifier or a multi-pole DC bus, order one per pole rather than expecting a matched set.
