Bussmann FLF-40 – Frequently Asked Questions

1) What amperage ratings does the Bussmann FLF fuse link come in?
Two amperages: FLF-20 at 20A and FLF-40 at 40A. Both are 32 Vdc cartridge fuse links with female termination, so the choice comes down to matching the amperage of the harness circuit you are protecting. Do not upsize to the 40A to stop nuisance opening - the link is sized to protect the wire.
2) Can I use a Bussmann FLF fuse link on a 120V or 240V AC circuit?
No. The FLF series is rated 32 Vdc only. It is a low-voltage DC automotive fuse link for vehicle wiring harnesses, not a branch-circuit fuse for building power. For AC panel or disconnect protection you need a class-rated cartridge fuse, not this part.
3) Will the Bussmann FLF fuse link fit a standard harness fuse holder?
The FLF body measures 1.25 IN height, .97 IN length/depth and .51 IN width, which is sized to drop into standard harness fuse holders without added bulk. Check those three numbers against the cavity you are replacing into, since fuse link holders vary by OEM.
4) Is the Bussmann FLF the right fuse link for a Japanese-built vehicle harness?
Yes, that is exactly what it is built for. The FLF series is specified for wiring harness protection in Japanese-designed vehicles, covering OEM and aftermarket harness assemblies and general low-voltage DC circuit protection. Match the existing link's amperage: 20A or 40A.
5) What is a female-termination fuse link and how does it connect in the harness?
The FLF is a cartridge-style fuse link whose body carries a female terminal, so it slips onto the male blade or tab already in the harness or fuse block rather than being bolted or crimped in line. That keeps the connection compact for tight harness routing and makes replacement a pull-and-push job with no wire work.
6) What does the 10 kAIC interrupt rating on the Bussmann FLF mean for my application?
10 kAIC is the maximum fault current the link can safely clear at its rated voltage. On a vehicle 12V/24V system a shorted battery feed can push very high current, and the 10 kAIC rating means the FLF opens that fault without rupturing. It applies at the 32 Vdc rating, not above it.
7) How do I tell if a Bussmann FLF fuse link has blown?
The FLF is non-indicating, so there is no pop-out pin or LED flag. You check it by visual inspection of the element or by continuity test with a meter across the terminals. On fleet service work that means pulling the link rather than eyeballing the block.
8) What is the exact Bussmann part number to order for a 40 amp fuse link?
FLF-40 is the 40A version; FLF-20 is the 20A. Both ship in standard packaging. Order by that MPN to avoid picking up a different Bussmann fuse family with the same amperage but a different termination.
