Bussmann FNM-30 – Frequently Asked Questions
1) Can I use a 250V fuse like the FNM-30 on a 480V control circuit?
No. The FNM-30 is rated 250 V, so it must not be applied above that. On a 480 V circuit you need a 600 V midget time-delay fuse instead. The FNM is the right choice on 120 V and 240 V control and motor circuits, where its 10 kAIC interrupting rating at 250 Vac covers the available fault current.
2) Is a time-delay midget fuse the right type for a motor starting load, or should I use a fast-acting one?
For a motor or any inductive load, time delay is what you want. The FNM-30 uses dual element construction, so it rides through the inrush of a motor start without opening, then still clears short circuits and sustained overloads. A fast-acting midget fuse in that same holder would nuisance-trip on every start. Fast-acting is for resistive or semiconductor loads with no inrush.
3) Does the FNM-30 have a blown-fuse indicator?
No, the FNM-30 is non-indicating. There is no pop-out pin or visible flag, so a tech troubleshooting a control panel has to pull it and check continuity, or read voltage across the holder. If your maintenance crew depends on a visual check, plan on an indicating-type fuse or a holder with an indicating light.
4) What is the exact part number and interrupting rating I should put on my submittal for this Bussmann midget fuse?
Order it as Bussmann FNM-30: FNM series, 30 A, 250 V, time-delay, dual element, ferrule x ferrule, 10 kAIC at 250 Vac. Note the 10 kAIC figure when you are doing a short circuit current rating check on a control panel, since that is the ceiling for this fuse.
5) Will the FNM-30 hold up in a humid or corrosive environment like a rooftop HVAC disconnect?
The endcaps are nickel-plated bronze, which resists corrosion and keeps contact resistance low in the clips over time. That is the usual reason these go into rooftop HVAC and pump control enclosures. It is still a bare fuse, so the enclosure itself has to provide the weather rating.
6) Does the Bussmann FNM-30 carry any compliance markings for export equipment?
The FNM-30 is CE marked, which matters if the panel or machine you are building ships into Europe. That is the compliance marking on record for this fuse.
