Bussmann SC-4 – Frequently Asked Questions

1) What amp rating is the Bussmann SC-4 fuse?
The Bussmann SC-4 is a 4 amp miniature fuse. The amperage is built into the model designation, so SC-4 always means the 4A rating in the SC series. If the fuse you pulled out of the holder is marked SC-4, this is the direct like-for-like replacement.
2) My equipment calls for an SC-4 fuse. Do I need to match anything else besides the amp rating?
Order by the SC-4 designation itself rather than by amperage alone. SC is a defined Bussmann series, so the SC-4 carries both the 4A rating and the series' physical and performance characteristics. Substituting a different 4A miniature fuse from another series may not match the body size or the holder.
3) Is the SC-4 the right fuse for a control panel build?
Yes. The SC-4 is a compact 4A miniature fuse intended for control panels, junction boxes and equipment enclosures where mounting space is tight, and for protecting control devices and low-current components. Panel builders and OEMs are the main users of it.
4) Can I use an SC-4 in place of a higher amp fuse in the same holder?
No. The SC-4 is calibrated to open at a 4A threshold, so dropping it into a circuit that normally draws more will cause nuisance openings. Going the other direction, fitting a larger fuse than the circuit was designed for, removes the protection the equipment maker specified. Match the rating the panel schedule or equipment label calls for.
5) What kind of circuits is a 4A miniature fuse like the SC-4 used to protect?
Low-current work: sensitive circuits, control components and small devices that would be damaged by excess current. Typical uses are electrical control panel builds, industrial and commercial equipment protection, OEM equipment, and general-purpose overcurrent protection on the low-amp side of a system. It is not a branch-circuit or feeder fuse.
