Bussmann FWP-150 – Frequently Asked Questions

1) Can the Bussmann FWP-150 be used on a DC circuit, or is it AC only?
Both. The FWP-150 carries a 700 Vac and 700 Vdc rating, so the same fuse covers AC circuits and DC circuits such as battery banks, rectifier output, and DC links up to 700 volts. That dual rating is why it gets specified on drive systems where the AC input and the DC bus both need protection without stocking two different fuse platforms.
2) Does the FWP-150 have a blown fuse indicator?
No. The FWP-150 is a non-indicating fuse, so there is no visual pop-up or pin to show it has opened and nothing to drive a microswitch off. If your panel design relies on a blown-fuse indication or a remote alarm contact, you need an indicating version of the series or a separate monitoring method. For straight overcurrent protection where a tech will meter the fuse, non-indicating is the normal choice.
3) What is a high-speed fuse like the FWP-150 for, and why not use a regular Class J or RK5 fuse?
High-speed (semiconductor) fuses such as the Bussmann FWP series clear faults far faster and with lower let-through energy than general-purpose branch-circuit fuses, which is what keeps diodes, SCRs, IGBT modules, rectifier stacks and drive front ends from being destroyed before the fuse opens. Use the FWP-150 where you are protecting power electronics. A conventional time-delay or dual-element fuse is the right pick for motor branch circuits and transformer inrush, where you want the fuse to ride through a starting surge instead of opening on it.
4) Is the FWP-150 suitable for a solar or battery energy storage DC disconnect?
It is applied in renewable energy, battery, and DC power system circuit protection, and the 700 Vdc rating covers typical PV string and battery bus voltages up to that limit. Confirm your maximum open-circuit DC system voltage sits at or below 700 V and that the holder is DC rated as well, since a fuse rating does nothing for you in an AC-only switch.
5) How does the FWP-150 ship, and can I stock it as a spare for a drive?
It ships in standard packaging, which is how most maintenance departments buy it as a shelf spare. At about .57 lb each it is easy to keep several on a shelf next to the drive cabinet, and because the same part covers both the 700 Vac and 700 Vdc side of the system, one spare line item covers more of the panel than a mixed set would.
6) Where does the Bussmann FWP-150 typically get installed?
Typical placement is inside industrial power electronics: variable frequency drive systems, semiconductor, rectifier and converter circuits, motor control centers, and control panels or panelboards needing fast-acting overcurrent protection. It is a component-level protection fuse, not a service-entrance or branch-circuit device.
