Bussmann FNM-1-1/2 Miniature Fusetron Time-Delay Fuse

The Bussmann Miniature Fusetron Time-Delay Fuse shown above is part of Bussmann's recognized FNM Series, a line of compact, cartridge-style fuses built for dependable overcurrent protection in space-constrained electrical and control circuits. As a Fusetron-branded fuse, it is designed around Bussmann's time-delay fuse technology, helping circuits ride through momentary inrush and surge currents without nuisance opening under normal starting conditions. The miniature cartridge form factor makes it a practical fit for equipment panels, control cabinets, and appliances where board space and fuse holder dimensions are limited. Bussmann fuses are manufactured to consistent quality standards, giving specifiers and maintenance teams a dependable option when matching an existing FNM Series fuse already in service.

Key Features

  • Miniature Fusetron Design: Compact cartridge construction sized for equipment and control panels with limited clearance around the fuse holder.
  • FNM Series: Manufactured as part of Bussmann's established FNM Miniature Fusetron fuse lineup, a widely specified family for low-amperage circuit protection.
  • Time-Delay Performance: Fusetron construction is engineered for time-delay operation, allowing the fuse to accommodate brief current surges rather than opening on momentary spikes.
  • Reliable Overcurrent Protection: Provides a sacrificial protective element that interrupts current flow in the event of a sustained overload, helping safeguard downstream wiring and components.
  • Standard Cartridge Format: Compatible with fuse holders and fuse blocks sized for miniature cartridge fuses, simplifying replacement in existing installations.
  • Genuine Bussmann Manufacturing: Produced by Bussmann, a long-established circuit protection manufacturer recognized across commercial, industrial, and OEM applications.
  • Trusted FNM Part Number: Cross-references directly to the Bussmann FNM Series numbering system, simplifying fuse identification and stocking for maintenance teams.

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

1) Will a time-delay fuse like the FNM stop nuisance blowing on a motor or transformer circuit?
That is what the Fusetron time-delay construction is for. The FNM-1-1/2 rides through the brief inrush that happens when a small motor, solenoid, or control transformer energizes, and opens on a sustained overload instead. If your circuit has been dropping fuses at startup and you were using a fast-acting fuse of the same rating, a time-delay FNM is the correct swap; if the circuit feeds solid-state electronics that need fast clearing, a time-delay fuse is the wrong choice.
2) Can I use the Bussmann FNM-1-1/2 in my existing fuse holder or fuse block?
The FNM is a miniature cartridge fuse, so it drops into holders and fuse blocks built for that miniature cartridge format. It will not seat in a holder sized for a full-size ferrule or knife-blade class fuse. The practical check is simple: if the fuse you are replacing is an FNM, this is an in-kind replacement and the clips will take it.
3) Is FNM the same as a Bussmann FNQ or FNM-R fuse?
No. FNM is Bussmann's Miniature Fusetron time-delay line, and it is the only family this part belongs to. Related Bussmann designations such as FNQ or FNM-R are separate part series with their own dimensions and characteristics, so a control panel or OEM machine specified around an FNM should be re-fused with an FNM of the same amperage. Match the full printed designation, FNM-1-1/2 in this case, rather than just the amp value.
4) What kind of equipment is a 1-1/2 amp miniature Fusetron fuse normally used in?
Low-amperage control work. Typical spots are control panels and control cabinets, industrial machine and OEM equipment circuits, instrument and appliance circuits, and fuse block replacements in panelboards. Maintenance shops also stock the FNM sizes as shelf spares because the compact body fits holders where there is little clearance around the fuse.
