Time-delay design provides protection for loads with brief surges, reducing nuisance trips while preserving equipment life. This translates to improved uptime and lower maintenance costs in control panels and motor control centers. The 0.3 A amperage rating targets low-current instrumentation and sensing circuits, delivering selective protection without sacrificing responsiveness in automation systems. Ferrule end x ferrule end connections and nickel-plated bronze endcaps enable quick, secure installations with reliable contact resistance, beneficial for harnessed wiring and field-service replacements. The 250 V rating paired with 10 kAIC at 125 Vac (and 35 AIC at 250 Vac) gives a robust safety margin for both AC and mixed-load environments, helping manufacturers meet electrical codes and minimize downtime due to faults. CE and RoHS compliance, standard packaging, and a non-indicating fuse indicator simplify procurement, stocking, and field servicing while supporting compliance objectives and repairability. Its compact dimensions (0.39 in × 0.39 in × 1.44 in) and standard Bussmann form factor ensure compatibility with common fuse holders and panel layouts, providing a practical, cost-effective solution for industrial control applications and instrumentation.

FAQs
The FNM-3/10 uses ferrule-end leads for quick, secure installation. Ensure wires are properly crimped into ferrules, insert into compatible fuse holders designed for ferrule-end contacts, and verify a tight fit with clean, undamaged terminals. This approach minimizes contact resistance and improves your protection reliability in control panels.
The fuse is rated at 0.3 A with a 250 V rating. Its interrupt ratings are 10 kAIC at 125 Vac and 35 AIC at 250 Vac, making it suitable for circuits that may experience short surges while needing robust protection for automation and instrumentation loads.
Yes. The FNM-3/10 is CE marked and RoHS compliant, ensuring conformity with European safety, health, and environmental directives. This makes it suitable for European equipment and assemblies requiring regulatory compliance without additional certification steps.
This time-delay, dual-element fuse is ideal for control panels, instrumentation, and small power circuits where inrush currents occur. Its combination of a 0.3 A rating and 250 V operation supports protection of low-current logic and sensing circuits while handling short surges typical in automation equipment.
The device features ferrule-end connections, nickel-plated bronze endcaps, and standard packaging. Dimensions are 0.39 in length and width with a height of 1.44 in, fitting many Bussmann-compatible holders and panel layouts. These attributes support straightforward replacement and service in existing Eaton Bussmann or Eaton-protected assemblies.
