Bussmann MIC-15 – Frequently Asked Questions
1) What amp ratings does the Bussmann MIC midget fuse come in?
Four ratings are offered in the MIC series: 15A (MIC-15), 20A (MIC-20), 25A (MIC-25) and 30A (MIC-30). Pick the rating that matches the circuit protection called out on your drawing or the fuse you are replacing, since all four share the same fast-acting element style and ferrule-to-ferrule body.
2) Will a Bussmann MIC fuse fit my standard fuse clips, or does it need a blade holder?
The MIC is a ferrule end by ferrule end fuse, so it drops into clip-style holders and blocks that grip a cylindrical end cap. It is not a blade or bolt-down fuse. Body size is 0.47 x 0.47 x 1.813 inches, so confirm your clip spacing accepts that length before ordering.
3) Is the Bussmann MIC a fast-acting fuse or a time-delay fuse?
Fast acting. The MIC element opens quickly on overcurrent with no intentional time delay, which is what you want on control, PLC and electronic circuits where downstream components will not tolerate a long let-through. If your load has an inrush surge, such as a motor or transformer, a fast-acting midget will nuisance-open and you should be looking at a time-delay midget instead.
4) Can you tell at a glance when a Bussmann MIC fuse has blown?
No. The MIC is non-indicating, so there is no pop-up pin or lit element to show an open fuse. Maintenance crews troubleshooting a panel will need to pull the fuse and meter it, or use a holder with its own blown-fuse indication.
5) What is the interrupting rating on the Bussmann MIC midget fuse?
The MIC series is rated 10 kAIC at 32 Vac. That figure is the available fault current the fuse can safely clear, and it needs to equal or exceed the calculated available fault current at the point in your circuit where the fuse sits.
6) What are the Bussmann MIC fuse end caps and body made of?
Nickel-plated bronze end caps on a fiber tube. The plated bronze caps give a low-resistance contact in spring clips and resist corrosion in control panels; the fiber body is the traditional midget construction.
7) How are Bussmann MIC fuses packaged for MRO stocking?
They ship in standard packaging, one catalog number per amp rating, so a facility standardizing a spares kit can stock MIC-15, MIC-20, MIC-25 and MIC-30 as separate line items rather than a mixed assortment.
