Eaton Specification Sheet - FNA-15/100
Time-delay operation with dual elements delivers deliberate overload tolerance, reducing nuisance trips and extending motor life in automation equipment. Business impact is improved uptime and smoother production throughput, especially where short overloads are common. This makes the FNA-15/100 well-suited for inductive loads in control panels, relays, and motor-start circuits where cycling efficiency matters. The 0.15 A amperage rating provides precise protection for low-current control loops, insulating sensitive devices from marginal faults and delivering safer startup conditions. Application wise, it supports electronics and automation components that demand stable protection without premature shutdowns, offering measurable efficiency gains and reduced maintenance costs. The fuse also supports standard Eaton Bussmann series installations, enabling straightforward procurement and consistent performance across panel builds.

FAQs
The FNA-15/100 is a standard 1.5 inch long, 0.406 inch wide fuse designed for common fuse holders in control panels. Its dual-element, time-delay construction supports inductive and electronic circuits, making it compatible with typical Bussmann-series enclosures and standard panel assemblies. When replacing, ensure wiring terminals match the silver-plated pin contacts for optimal conductivity and inspect for any signs of overheating in the holder.
This fuse is a time-delay (slow-blow) type with a dual element, which tolerates short-duration current surges common in inductive loads and motor startup. Its 0.15 A rating with high interrupt capability (10 kAIC at 125 Vac and 35 AIC at 250 Vac) protects circuits from sustained faults while allowing brief inrush currents, reducing nuisance trips and extending equipment life.
Yes. The FNA-15/100 is CE marked and RoHS compliant, ensuring adherence to European regulatory requirements and environmental directives. This supports regulatory confidence for panel builders and end users, simplifying audit trails and supplier qualification.
Ideal for control panels, automation equipment, and sensor or PLC power circuits where reliable overload protection with minimal nuisance trips is essential. Its compact form factor and robust interrupt ratings make it a practical choice for compact enclosures and higher-duty automation environments.
By reducing nuisance tripping and downtime in inductive circuits, the FNA-15/100 helps improve equipment uptime and production throughput. Its long cycle life and compatibility with standard Bussmann-series components reduce maintenance frequency and spare-part complexity, delivering lower operating costs over the life of the installation.
