Bussmann FNM Series Miniature Fusetron Fuse

The Bussmann FNM Series Miniature Fusetron fuse is engineered for dependable overcurrent protection in compact electrical and electronic equipment. This listing covers the full FNM miniature fuse family, available in amperage ratings from 0.2 A up to 3.2 A (including 0.2A, 0.6A, 1.25A, 1.6A, 1.8A, 2.8A, and 3.2A options), so technicians can select the exact rating required for a given circuit or replacement application. As part of Bussmann's established Fusetron miniature fuse lineup, each FNM model is identified by its amp rating built directly into the model designation, making it straightforward to source an exact match when replacing an existing fuse of the same part number. The miniature form factor allows FNM Series fuses to fit into tight fuse holders, in-line fuse clips, and low-profile circuit protection assemblies where standard full-size fuses will not fit. This makes the FNM Series a practical choice when technicians need to confirm compatibility quickly by matching the printed part number rather than cross-referencing separate specification sheets. Electricians, technicians, and equipment maintenance teams rely on correctly rated Bussmann Fusetron fuses like the FNM Series to keep control circuits and low-amperage electrical assemblies protected against unwanted overcurrent conditions.

Key Features

  • Series Designation: FNM identifies this unit within the Bussmann Fusetron miniature fuse family.
  • Amp Rating Range: Available from 0.2 A through 3.2 A, built into each model number for straightforward cross-reference and replacement.
  • Miniature Fusetron Design: Compact Fusetron-series construction suited to space-constrained fuse holders and control panels.
  • Bussmann Manufacturing: Produced by Bussmann, a long-standing name in circuit protection components.
  • Direct Replacement: Matches the printed FNM part number for like-for-like replacement in existing equipment.
  • Compact Footprint: Small physical size supports installation in space-limited fuse blocks, holders, and equipment panels where a full-size fuse will not fit.
  • Simple Identification: The FNM part number is printed on the fuse body for quick visual confirmation during replacement.
  • Cross-Reference Friendly: The FNM designation simplifies inventory management and reordering for maintenance teams stocking Bussmann Fusetron fuses across multiple amp ratings.

Bussmann FNM-3-2/10 – Frequently Asked Questions

1) What amp ratings can I get in a Bussmann FNM miniature Fusetron fuse?
Orderable FNM ratings run 0.2 A (FNM-2/10), 0.6 A (FNM-6/10), 1.25 A (FNM-1-1/4), 1.6 A (FNM-1-6/10), 1.8 A (FNM-1-8/10), 2-1/2 A (FNM-2-1/2), 2.8 A (FNM-2-8/10), 3.2 A (FNM-3-2/10) and 6-1/4 A (FNM-6-1/4). The amp value is carried in the part number itself, so the fraction after FNM is the rating you are buying.
2) The fuse in my control panel is printed FNM-1-6/10. Is that the same thing as a 1.6 amp fuse?
Same part. FNM-1-6/10 is Bussmann's fractional way of printing 1.6 A, and it is the 1.6 A option in the FNM line. The same reading applies across the family: 2/10 is 0.2 A, 6/10 is 0.6 A, 1-1/4 is 1.25 A, 3-2/10 is 3.2 A. Match the printed number on the body and you get a like-for-like replacement.
3) Will a Bussmann FNM fuse fit a small in-line fuse holder or a low-profile fuse block?
That is what the FNM miniature Fusetron is built for. It is a miniature-format fuse intended for tight fuse holders, in-line fuse clips and low-profile circuit protection assemblies where a full-size fuse will not physically go. If your holder was originally fitted with an FNM, the replacement drops straight in; if you are specifying a holder from scratch, check that it is dimensioned for the FNM miniature body rather than a full-size cartridge.
4) Can I use a higher amp FNM fuse if the exact rating is out of my stock?
No. Fit the rating the circuit was designed around. Going up, for example dropping a 2.8 A FNM-2-8/10 into a holder specified for 1.8 A FNM-1-8/10, lets more current through before the element clears and removes the protection the fuse was there to provide. The FNM line is offered in close steps (0.2, 0.6, 1.25, 1.6, 1.8, 2-1/2, 2.8, 3.2 and 6-1/4 A) precisely so you can match the exact rating.
5) Is the Bussmann FNM fuse body glass, so I can see whether the element has blown?
The FNM fuse body is glass, which means a blown element is visible on inspection instead of needing a meter. For maintenance teams that is the practical advantage: pull the fuse, look at the element, and confirm the fault before you swap it.
6) We stock fuses for several control panels. Which FNM ratings should we keep on the shelf?
The FNM range spans 0.2 A to 3.2 A on the published rating, with 2-1/2 A and 6-1/4 A also available as orderable options, so a maintenance crib covering low-amperage control circuits usually stocks the ratings actually printed on the equipment rather than the whole range. Because the amp value is part of the FNM number, you can build your stock list straight off the fuses already in the panels: record the printed designation (FNM-6/10, FNM-1-1/4, FNM-2-1/2 and so on) and reorder against it with no cross-referencing.
7) What kind of circuits are Bussmann FNM Fusetron fuses used in?
Low-amperage work: electronic equipment and control circuits, fuse blocks and in-line holders, and industrial or commercial electrical panels, plus OEM and like-for-like replacement in existing Bussmann-equipped assemblies. With the top published rating at 3.2 A, these are control and electronics protection fuses, not branch-circuit or feeder fuses.
