Bussmann HPV-D15V-4A – Frequently Asked Questions

1) What wire size does the Bussmann HPV-D15V-4A in-line fuse holder accept?
The HPV-D15V-4A in-line fuse assembly is built for #12 through #8 AWG copper conductors. If your run is smaller than #12 or larger than #8 Cu, this housing is not the right termination for it.
2) Is the Bussmann HPV-D15V-4A rated for DC solar and battery circuits, or is it an AC fuse?
This is a DC device. The HPV assembly carries a 33 kA DC short-circuit interrupting rating and is intended for DC power distribution: PV arrays, battery banks, EV charging gear, and combiner boxes. Don't specify it as an AC branch-circuit fuse.
3) Will a 4A in-line fuse holder fit inside a crowded combiner box or panel?
The HPV-D15V-4A body is 2.99 in long and .55 in in diameter, weighing .1 lb, so it mounts in-line along the conductor rather than needing panel real estate. Allow clearance for the 2.99 in length plus the wire bends at each end.
4) What amperage is the Bussmann HPV-D15V-4A, and how do I size it for my string?
It is a 4 A device. Size the fuse to the circuit it protects, not to the conductor alone: at 4 A this suits low-current DC branches such as individual PV source circuits or control and monitoring feeds. Larger array or battery conductors need a higher-amp HPV part number.
5) Does a 33kA DC interrupting rating matter for a battery energy storage install?
It does. Battery banks can deliver very high available fault current, and the fuse has to be able to clear it. The HPV in-line assembly is rated to interrupt 33 kA DC, which is what lets it break a bolted fault at the battery instead of failing open violently.
6) What exact part number do I order for the Bussmann 4A HPV in-line fuse?
Order Bussmann (Eaton) HPV-D15V-4A. That is the full manufacturer part number for the 4 A version of the HPV in-line assembly in the black housing.
