Eaton FNM-5 Fuse - Time-delay, 10kAIC/200AIC CE RoHS
Part Number: FNM-5
Quick Summary
The Eaton FNM-5 fuse provides reliable time-delay circuit protection for 250 V control panels and small motors. Many automation projects suffer from nuisance trips and short cycle lifetimes that drive downtime and service costs. It is CE marked and RoHS compliant, helping you meet European regulatory requirements and sustainability goals. With a compact 1.5 in length and dual-element design, it installs quickly into standard fuse holders while offering superior overload handling. Nickel-plated bronze endcaps and ferrule-end connections ensure durable electrical contact in harsh industrial environments. This combination delivers predictable protection for motor drives and automation circuits while enabling straightforward sourcing.

Time-delay protection tolerates short inrush currents, reducing nuisance trips and boosting machine uptime. The business impact is fewer unscheduled shutdowns and lower maintenance costs, making it ideal for automation panels controlling actuators and small motors. Use cases include conveyor drives and machine-control loops where brief surges occur during startup. High interrupt ratings of 10 kAIC at 125 VAC and 200 AIC at 250 VAC allow safe fault clearance without arcing, protecting panel equipment and personnel while helping you meet safety goals for CNCs and automated lines. Dual-element design improves predictability across cycling events; the result is longer fuse life in high-cycle applications and reduced replacement costs. Ferrule-end x ferrule-end connections and nickel-plated bronze endcaps offer durable, corrosion-resistant contacts that withstand harsh shop floors and outdoor installations. In compact control enclosures, the FNM-5 enables reliable protection without crowding the panel. CE marking and RoHS compliance support regulatory alignment, while the 5 A rating suits small-load circuits and intelligent controllers, reducing over-specification and spare-part inventory. Superior overload and cycling capabilities are built to endure the demands of modern automation, delivering consistent performance in manufacturing environments.

FAQs
The FNM-5 uses ferrule-end connections and a compact 1.5 in length with a 0.41 in profile. It plugs into standard Bussmann-style fuse holders without special tooling. Ensure the holder is rated for 250 V and that the circuit current does not exceed 5 A. Use proper labeling and panel documentation to prevent misplacement during maintenance.
It combines a time-delay design with a 5 A rating and high interrupt capability (10 kAIC at 125 VAC, 200 AIC at 250 VAC). This reduces nuisance trips during startup and peak loads, while still protecting sensitive automation components like controllers and small motors in control cabinets.
Yes. The FNM-5 is CE marked and RoHS compliant, ensuring suitability for European installations and adherence to material and environmental regulations. This helps simplify procurement for global projects and supports sustainability initiatives.
Yes. Its time-delay behavior is well-suited for motor-start surges, and the 5 A rating fits small-load circuits. The high fault-interrupt ratings reduce risk of damage to drive components, wiring, and panels during fault conditions, improving overall equipment uptime.
