Bussmann FLB-100 – Frequently Asked Questions

1) What amp ratings does the Bussmann FLB fuse link come in?
The FLB Series cartridge fuse link is offered in eight ratings: 30A, 40A, 50A, 60A, 70A, 100A, 120A and 140A, ordered as FLB-30 through FLB-140. There is no 80A or 90A step in the range, so if the harness calls for one of those, size to the next rating the circuit and wire gauge will tolerate rather than substituting blind.
2) Can I use a Bussmann FLB fuse link on a 24 volt truck system?
The FLB fuse link carries a 32Vdc rating, which covers nominal 12V and 24V DC vehicle systems since charging voltage stays under 32V. It is a DC-only device, so do not put it on AC circuits.
3) How does the FLB fuse link mount, and do I need a fuse holder?
It's a bolt-down part, not a push-in. The FLB uses a 13/16 in bolt terminal connection and bolts directly to a fuse block or battery-terminal stud, which is what keeps it from backing out under vibration. You supply the block or stud and the hardware; the fuse link itself is just the cartridge.
4) Is the Bussmann FLB the right fuse link for a Toyota or Honda wiring harness?
That is exactly what it is built for. The FLB Series is specified for wiring harness protection in Japanese-designed vehicles, which is why it uses the bolt-terminal cartridge format those platforms run in the underhood fuse block rather than a blade-style fuse.
5) Will I be able to see when a Bussmann FLB fuse link has blown?
No. The FLB is a non-indicating design, with no pop-up pin or LED to flag a blown element. Diagnosis is by continuity check or voltage drop across the terminals. If a fleet tech needs at-a-glance fault spotting, this is the wrong style of fuse link for that.
6) What does the 10 kAIC rating on this fuse link actually mean for my install?
10 kAIC is the maximum fault current the FLB can safely interrupt without rupturing. A shorted main harness lead straight off a vehicle battery can push very high current, and this rating is what lets the fuse link clear that fault cleanly instead of arcing. It is an interrupt capacity, not the amp rating, so a 30A FLB still opens at its 30A element.
7) Can a fleet shop standardize on FLB fuse links across several amp ratings?
Yes, and it's a sensible stocking move. All eight ratings share the same 13/16 in bolt terminal and the same 32Vdc, 10 kAIC platform, so one block style and one set of mounting hardware covers the whole 30A to 140A spread. Order by part number, FLB-30, FLB-40, FLB-50, FLB-60, FLB-70, FLB-100, FLB-120, FLB-140.
8) Can I use an FLB fuse link to protect a 120V branch circuit or a panelboard?
No. The FLB is a 32Vdc automotive fuse link for vehicle wiring harnesses, and it has no line-voltage AC rating. For building branch circuits you need a standard class fuse or breaker rated for that system voltage.
