Bussmann FLF-20 – Frequently Asked Questions

1) Can the Bussmann FLF-20 fuse link be used on a 24V truck electrical system?
Yes. The FLF-20 is rated 32 Vdc, so it covers both 12V and 24V DC vehicle systems, which both sit below that ceiling. It is a DC-rated fuse link only, so do not put it on an AC circuit. Current rating is 20A with a 10 kAIC interrupting rating.
2) What does female termination mean on the FLF-20 fuse link, and will it plug into my harness?
Female termination means the fuse link body carries the receptacles and the harness studs or male blades push into it, rather than the fuse having spade tabs of its own. It is a cartridge style fuse link built for Japanese designed vehicle wiring harnesses, so it mates with harness holders using male terminals. If your harness block has female receptacles waiting for blades, this is the wrong termination style.
3) Can I substitute a 30A fuse link if I cannot get a 20A one?
No. The FLF-20 is a 20A device and the rating is chosen to protect the wire gauge in that harness branch, not the load. Going up to 30A lets the conductor carry more current than it is sized for before the link opens, which is how harness fires start. Replace like for like at 20A.
4) Will the Bussmann FLF-20 fit in a tight harness run behind the fuse box?
Body size is 1.25 in height, .97 in length/depth and .51 in width, and it weighs .2 lb. That footprint drops into standard harness fuse holders without needing extra clearance, but measure the pocket if you are routing it in a confined loom channel.
5) Can you tell at a glance whether an FLF-20 fuse link has blown?
No. The FLF-20 is a non-indicating fuse link, so there is no pop-out pin or LED to flag an open. Diagnose it the usual way, pull it and check continuity, or test for voltage on both sides of the holder with the circuit live.
6) What does the 10 kAIC interrupt rating on this fuse link actually buy me?
It is the maximum fault current the FLF-20 can clear safely without rupturing. On a 32 Vdc harness fed by a vehicle battery, available short circuit current can run high, and a 10 kAIC device is sized to open that fault rather than fail open violently. It matters most on links sitting close to the battery, where prospective fault current is highest.
7) What part number do I order for the Bussmann 20A female termination fuse link?
Order Bussmann FLF-20. The FLF prefix is the female termination fuse link family and the 20 is the amp rating, so a 20A female link is FLF-20. It ships in standard packaging.
8) Is the FLF-20 suitable for a fleet shop stocking repairs on Japanese import vehicles?
That is exactly what it is built for. The application is wiring harness protection in Japanese designed vehicles, covering OEM and aftermarket harness assemblies and replacement of existing fuse links in those systems. For a fleet running mixed domestic and import units, it only covers the import harnesses that use the female cartridge link format.
