Bussmann FNQ-1-1/2 – Frequently Asked Questions

1) What amperage ratings does the Bussmann FNQ Fusetron miniature fuse come in?
The FNQ Fusetron miniature fuse is offered in five ratings: 0.4A (FNQ-4/10), 6/10A (FNQ-6/10), 1.5A (FNQ-1-1/2), 1.6A (FNQ-1-6/10), and 3.2A (FNQ-3-2/10). The catalog number carries the rating as a fraction, so a 6/10 amp fuse orders as FNQ-6/10 rather than FNQ-0.6.
2) I need to replace a blown FNQ fuse in a control panel - how do I order the right one?
Read the amp rating printed on the body of the old fuse and match it to the FNQ catalog number: 4/10, 6/10, 1-1/2, 1-6/10, or 3-2/10. Replace with the same rating, not a higher one. The FNQ prefix is the Bussmann Fusetron miniature series designation, so an FNQ-1-1/2 is the direct catalog-matched replacement for a 1.5 amp FNQ.
3) Will the Bussmann FNQ fuse fit a small fuse holder in a tight panel?
The FNQ is a miniature-format Fusetron fuse, built for standard miniature fuse holders, blocks, and panels where space is limited. Match the holder's clip size and voltage requirement to the fuse body before installing; the FNQ is the small-footprint option in the Fusetron line.
4) Are Bussmann FNQ fuses suitable for control circuit protection in industrial equipment?
Yes. The FNQ Fusetron fuses are used for control circuit and panel protection, industrial and commercial electrical equipment, OEM assemblies, and general maintenance work. The low ratings available, 0.4A up to 3.2A, are the range typical of control transformer secondaries and instrument circuits rather than feeder or branch circuits.
5) Can I use a 3.2A FNQ fuse in place of a 1.5A one if that is what I have on hand?
No. Going up from 1.5A to 3.2A lets roughly twice the current through before the fuse opens, which defeats the protection the circuit was designed around. Order the matching rating: FNQ-1-1/2 for 1.5A. The series spans 0.4A, 6/10A, 1.5A, 1.6A and 3.2A so there is a catalog number for each step.
6) What is the difference between FNQ-1-1/2 and FNQ-1-6/10?
Only the current rating. FNQ-1-1/2 is 1.5 amps and FNQ-1-6/10 is 1.6 amps, both miniature Fusetron fuses in the same FNQ family. The two sit one step apart in the series, so stocking the correct one matters when a nameplate or schematic calls out a specific rating.
