Eaton FNA-5-6/10 Fuse - Dual Time-Delay, 200 kAIC
Part Number: FNA-5-6/10
Quick Summary
The Eaton FNA-5-6/10 fuse is a dual-element time-delay protection device designed for inductive and electronic loads in industrial control panels. Nuisance trips from inrush currents can drive maintenance costs and downtime; this fuse mitigates those issues by allowing brief surges without opening the circuit. Certified for CE marking and RoHS compliance, it also delivers robust safety margins with a 250 V rating and high interrupt capabilities—10 kAIC at 125 Vac and 200 kAIC at 250 Vac. In practice, it pairs well with standard Bussmann-series holders and panel assemblies, delivering reliable protection with low lifecycle costs. Its silver-plated pins support dependable connections, while its standard packaging streamlines stocking and installation for engineering teams.

Eaton Specification Sheet - FNA-5-6/10
Time-delay design enables brief inrush currents to pass without nuisance trips. This reduces equipment downtime and extends motor life by avoiding premature fuse opens in control panels. Applications include motor starters, transformers, and power supplies in manufacturing lines. 5.6 A amperage rating provides precise protection for low-current control circuits while limiting fault current exposure. This translates to fewer unnecessary replacements and better energy performance in electronic controllers. Compatible with standard Bussmann-series holders and 250 V systems across industrial plants. High interrupt ratings of 10 kAIC at 125 Vac and 200 kAIC at 250 Vac give robust fault isolation for inductive loads and large inrush events, improving safety margins. In practice, this supports compliance with electrical protection codes while maintaining service continuity for critical equipment. Silver-plated pins and dual-element construction enhance connection reliability and thermal stability. Packaging is standard for easy stocking and quick replacement in field panels, and the fuse offers non-indicating operation to minimize nuisance indications in control logic. Compliance with CE and RoHS reduces regulatory risk and simplifies procurement across multi-site operations. The special features deliver superior overload and cycling capabilities, contributing to longer service life in demanding industrial environments.

FAQs
Yes. The FNA-5-6/10 is designed as a dual-element, time-delay fuse for standard Bussmann-series protection devices. It uses silver-plated pins for reliable connections and ships in Standard packaging for easy stocking. It is compatible with Eaton Bussmann holders and panel assemblies that accept 1.5 inch length fuses, helping maintain a consistent protection footprint across panels.
The FNA-5-6/10 provides 10 kAIC at 125 Vac and 200 kAIC at 250 Vac. These high interrupt ratings translate to safer and more reliable fault isolation for inductive loads and surge events, reducing the risk of cascading faults and enabling safer shutdowns in motor drives, transformers, and power supplies.
Best suited for inductive and electronic loads in control panels, including motor starters, transformers, and power supplies. The time-delay characteristic accommodates startup surges while the 5.6 A rating protects control circuits from overcurrent. Its dual-element design further enhances reliability in environments with frequent inrush and cycling.
The FNA-5-6/10 is CE marked and RoHS compliant, signaling conformity to European safety, health, and environmental standards. These certifications simplify multi-site procurement, support regulatory compliance, and reduce risk for design wins in regulated industries such as industrial automation and process control.
The fuse reduces maintenance costs by minimizing nuisance trips and extending equipment life through controlled inrush handling. Its compatibility with standard holders simplifies stocking and replacements, while its robust interrupt ratings improve protection margins. Overall, you can expect lower downtime, fewer spare parts, and more predictable maintenance planning in high-demand manufacturing environments.
