FNM-1/2~FNM-1-2~BUSS MIDGET FUSE
Time-delay, dual-element design provides overload protection with a controlled response, reducing nuisance trips and improving equipment uptime in PLC inputs and motor starters. The 0.5 A rating paired with high interrupt capability translates to dependable protection for sensitive circuits, while the 35 AIC at 250 Vac and 10 kAIC at 125 Vac offer strong short-circuit resilience, minimizing damage during faults and accelerating recovery. Ferrule-end x ferrule-end connections with nickel-plated bronze endcaps deliver durable, low-resistance terminations that streamline installation and maintenance within existing Bussmann harness ecosystems. CE Marked and RoHS compliant status ensures regulatory alignment and sustainability compliance across EU deployments, while standard packaging and the 1.5 in length support straightforward panel mounting and fast deployment in new builds. Non-indicating operation reduces maintenance checks and simplifies routine servicing in high-cycle environments. Overall, the FNM-1/2 adds reliability, minimizes downtime costs, and integrates smoothly with automation panels and control cabinets.

FAQs
The FNM-1/2 fuse provides time-delay protection for low-current control circuits, such as PLC inputs, relays, and small motors, in industrial panels. Its dual-element design tolerates startup surges while preserving circuit integrity, reducing nuisance outages. It is compatible with ferrule-end terminations and Bussmann-series harnessing, simplifying retrofit or new panel builds and enabling predictable protection in automation systems.
The fuse is rated for 0.5 A with an interrupt rating of 35 AIC at 250 Vac and 10 kAIC at 125 Vac, with a 250 V voltage rating. This combination provides reliable short-circuit protection for low-current circuits while allowing safe interruption of fault conditions in standard European and North American panel environments.
Yes. The FNM-1/2 uses ferrule end x ferrule end connections and features nickel-plated bronze endcaps. This configuration delivers durable, low-resistance terminations, simplifies installation, and supports reliable cycling in control cabinets and automation panels.
The device is CE Marked and RoHS Compliant, ensuring regulatory alignment for European installations and reduced hazardous substances in line with modern procurement standards. These certifications support compliance during audits and help streamline global deployments in automation projects.
Choosing the FNM-1/2 reduces spare-parts variety due to its standard Bussmann-series compatibility, shortens commissioning time with a compact 1.5 in length, and enhances uptime thanks to robust time-delay protection. The result is lower maintenance costs and faster project ROI in automation and control-panel environments.
