Bussmann FWP-70 – Frequently Asked Questions

1) Can the Bussmann FWP-70 fuse be used on a DC circuit, or is it AC only?
Both. The FWP-70 carries a 250 Vac/dc rating, so it can be applied on either AC or DC circuits up to 250 volts. That dual rating is why the FWP series shows up in drive, rectifier, and control panel work where the bus is DC but the upstream gear is AC. Do not apply it on a system whose nominal voltage exceeds 250 V.
2) Does the FWP-70 have a blown fuse indicator?
No. The FWP-70 is built in the Non-Indicating configuration, so there is no pop-up pin or visual blown-fuse flag on the body and no provision for driving a microswitch indicator. If your panel relies on a visual trip indication, you need an indicating-style fuse instead, or a separate monitoring relay.
3) Is the FWP-70 a direct replacement for an FWP fuse already in my panel?
Yes, within the same series and rating. The FWP-70 is a standard-configuration Eaton Bussmann FWP series fuse, intended as a like-for-like swap where an FWP-70 is already installed. Match the part number on the old fuse body exactly, including the amp number after the dash, because FWP fuses of different ratings are not interchangeable in the same holder.
4) What does a high-speed fuse like the Bussmann FWP-70 protect that a standard fuse will not?
High-speed (semiconductor) fuses such as the FWP series clear far faster than a conventional branch-circuit fuse, which is what power semiconductors need. Diodes, SCRs, and IGBTs fail in milliseconds under fault current, so the fuse has to let through less energy than the device can absorb. Use the FWP-70 for semiconductor and equipment protection; it is not a substitute for a time-delay fuse feeding a motor, where inrush would nuisance-blow it.
5) What are the dimensions and weight of the Bussmann FWP-70 so I can check it against my fuse holder?
The published figures are 1.26 in height, 1.24 in length/depth, and 4.86 in width, with a weight of .34 lb. Measure your existing fuse body and mounting centers against those before ordering, since high-speed fuse blocks are built around a specific body size and blade or ferrule pattern.
6) What part number should I put on a purchase order for this Bussmann high-speed fuse?
Order it as Eaton Bussmann FWP-70. That manufacturer part number covers the 250 Vac/dc, non-indicating, standard-configuration high-speed fuse and is what should appear on the spec line and the fuse body alike.
7) How is the Bussmann FWP-70 packaged for MRO stocking?
It ships in Standard packaging as a single FWP-70 fuse. For maintenance stores, high-speed fuses are usually held as spares in pairs or sets matched to the drive or rectifier they protect, since a fault often takes more than one leg.
