Bussmann FWP-15A14F High-Speed Ferrule Fuse, 700V/800Vdc, 15A

The Bussmann FWP-15A14F is a high-speed fuse from the Eaton Bussmann FWP series, engineered for semiconductor and power electronics circuit protection. Rated 700 Vac and 800 Vdc (UL), plus 690 Vac (IEC), this 15A fuse delivers 200 kAIC interrupting capacity at 300 Vdc and 50 kAIC at 300 Vdc, with a non-indicating, ferrule end x ferrule end body designed for direct in-line mounting in compatible fuse holders and blocks.

Key Features

  • Amperage Rating: 15A rated for reliable overcurrent protection in semiconductor and power electronic circuits.
  • Dual AC/DC Voltage Rating: 700 Vac and 800 Vdc (UL) plus 690 Vac (IEC) rating supports both AC and DC protection applications across UL and IEC markets.
  • High Interrupting Capacity: 200 kAIC at 300 Vdc and 50 kAIC at 300 Vdc for dependable clearing of high fault currents.
  • Ferrule End x Ferrule End Configuration: dual ferrule terminals sized for compatible fuse holders and blocks in compact installations.
  • Non-Indicating Body: standard non-indicating design without a blown-fuse indicator pin.
  • High-Speed Operation: fast-acting time-current response engineered to protect sensitive semiconductor devices from short-circuit and overcurrent damage.

Bussmann FWP-15A14F – Frequently Asked Questions

1) Can the Bussmann FWP-15A14F be used on a DC bus, or is it AC only?
Both. The FWP-15A14F carries a UL rating of 700 Vac and 800 Vdc, plus a 690 Vac IEC rating, so it can be applied on AC circuits or on a DC bus up to 800 Vdc. That dual rating is why the FWP series shows up on rectifier and converter sections as well as the AC input side of a drive.
2) Will a 15A FWP fuse mount in a standard fuse block, or does it need bolt-down lugs?
It is a ferrule end x ferrule end body, so it clips into a fuse holder or fuse block rather than bolting down. If your gear is set up for blade or bolt-on semiconductor fuses, this one will not drop in, you would need the flush-end or bolted style instead.
3) Is a high-speed semiconductor fuse like the FWP-15A14F the right choice for protecting a VFD, or should I use a standard Class J or RK5 fuse?
For the semiconductor stack itself, a high-speed fuse is the right tool. The FWP series is fast-acting and built to clear before the IGBTs or diodes in a drive, rectifier, or converter are damaged. Standard branch-circuit fuses (Class J, RK5) protect conductors and are too slow to save a semiconductor. Many drive installs use both: a branch-circuit fuse upstream for code compliance and an FWP at the device.
4) Does the Bussmann FWP-15A14F have a blown-fuse indicator?
No. It is a non-indicating body with no indicator pin, so there is nothing to trip a microswitch for remote blown-fuse signalling. If your panel relies on a mechanical indicator or trip switch for fault annunciation, you need an indicating version instead.
5) Is the FWP-15A14F UL Listed for use in a commercial panel?
Yes, it is UL Listed, rated by UL at 700 Vac and 800 Vdc, and separately rated 690 Vac to IEC. That makes it usable in both North American UL-based builds and export equipment built to IEC.
6) What is the exact Bussmann part number to order for a 15 amp FWP ferrule fuse?
The part number is FWP-15A14F, an Eaton Bussmann FWP series high-speed fuse rated 15A. The 15A in the designation is the ampere rating and the F suffix denotes the ferrule end construction.
7) Can the FWP-15A14F handle a high available fault current on an industrial service?
Yes. The FWP-15A14F is rated 200 kAIC interrupting capacity at 300 Vdc, which covers high fault-current industrial feeds and drive DC links. Confirm your voltage matches the condition the rating applies to when you do the short-circuit study.
