Bussmann SFE-4 – Frequently Asked Questions

1) Will a Bussmann SFE fuse fit my classic car's original fuse block?
SFE fuses use ferrule (cylindrical end cap) terminals and are made to drop into SFE-style fuse holders and panels, which is what most classic and vintage vehicle fuse blocks use. If your clips are the spring-clip type that grip a glass tube at each end, this is the right family. Note that SFE fuses vary in length by amp rating, so the clip spacing has to match the specific rating you order.
2) Can I substitute a 30 amp SFE fuse for a 4 amp one if that's what I have on hand?
No. Fuse amperage has to match the circuit it protects, and the two ratings offered here (SFE-4 and SFE-30) are not interchangeable. Dropping a 30 amp fuse into a circuit rated for 4 will let enough current through to damage the wiring and components the fuse was there to protect. Replace like for like with the rating marked on the original.
3) What amp ratings does the Bussmann SFE automotive fuse come in?
Two ratings: SFE-4 (4 amp) and SFE-30 (30 amp). Both ship 100 fuses per pack, so this is a shop or fleet quantity rather than a single replacement.
4) Is the Bussmann SFE-30 a fast-acting or a slow-blow fuse?
Fast-acting. It is built to open quickly on an overcurrent, which is what you want protecting vehicle wiring, connectors and electronic components rather than a motor load with a big inrush. If your circuit nuisance-blows on startup surge, a fast-acting fuse is the wrong choice for it.
5) Can I use a Bussmann SFE fuse in an industrial control panel instead of an automotive circuit?
No. The SFE fuse is a miniature automotive-classification fuse, purpose-built for vehicle electrical circuit protection rather than general industrial use. For a control panel you want a fuse carrying the appropriate industrial class rating and holder, not an SFE.
6) Does the Bussmann SFE fuse pack of 100 come in bulk or individually carded?
It is supplied as a 100 piece pack, one amperage rating per pack. Buy by the rating you need; a mixed-amp assortment is not how it ships.
