Eaton Specification Sheet - FNA-2-8/10
Feature: Time-delay, dual-element design provides selective protection for motors and electronic circuits. Business Impact: Reduces nuisance trips during startup and cycling while maintaining reliable protection across mixed load profiles. Application: Suitable for conveyors, pumps, and drive trains in industrial panels. The extended delay accommodates inrush currents without compromising the overall fault protection. Feature: High interrupt rating of 200 kAIC at 250 Vac (and 10 kAIC at 125 Vac) delivers robust fault tolerance. Business Impact: Shields downstream components and power feeders from catastrophic faults, lowering downtime and service costs. Application: Critical in automated lines and power-distribution segments where fault currents can spike. Feature: Dual-element construction with non-indicating status supports durable cycling with minimal maintenance. Business Impact: Improves predictability in automated systems and reduces replacement frequency, aiding in total cost of ownership. Application: OEM and retrofit projects requiring consistent protection with low field adjustments. Feature: Silver-plated pins and standard packaging enable easy integration into existing fuse holders. Business Impact: Simplifies installation, improves contact reliability, and lowers commissioning time. Application: Panel builders and machinery builders upgrading control circuits. Feature: CE-marked compliance and Bussmann-series compatibility ensure interoperability and regulatory alignment. Business Impact: Helps meet European safety standards while preserving supply-chain consistency for spares and service. Application: Global OEMs adopting standardized protection across platforms.

FAQs
Install the FNA-2-8/10 into a compatible fuse holder designed for Bussmann-series time-delay fuses. Ensure the holder contacts are clean and aligned with the silver-plated pins, and insert with a gentle, straight seating motion. Confirm the circuit voltage is within 250V and that the panel is de-energized before replacing a fuse to avoid electric shock or equipment damage.
This fuse excels in protecting inductive loads and mixed electronic circuits found in industrial control panels, conveyors, motors, pumps, and drive systems. Its time-delay (dual-element) design handles motor inrush without nuisance trips, while maintaining strong short-circuit protection thanks to a 200 kAIC interrupt rating.
Yes. The FNA-2-8/10 carries CE marking, indicating compliance with European safety requirements. While the data provided does not specify other certifications, the product aligns with Bussmann-series standards and is designed for reliable protection in 250V systems with strong interrupt performance.
The fuse is rated at 2.8A and 250V. Its interrupt ratings are 200 kAIC at 250 Vac and 10 kAIC at 125 Vac, supporting strong fault protection across varying load conditions commonly found in industrial equipment and automation panels.
Use a compatible Bussmann-series fuse holder and ensure clean, corrosion-free contacts for the silver-plated pins. Verify correct orientation and secure seating to prevent micro-movements, which can affect contact resistance. Consider the dual-element time-delay design when planning protection for systems with inrush currents from motors or electronic loads.
