Eaton Specification Sheet - FNA-1-1/8
FNA-1-1/8~FNA-1-1-8~FUSETRON DUAL-ELEMENT INDICATING
Time-delay and dual-element construction reduces nuisance trips during motor starts and transformer energization, delivering smoother operation and less downtime in automation panels. The unit’s 1.125 A, 250 V rating with 10 kAIC at 125 Vac and 200 kAIC at 250 Vac ensures reliable short-circuit protection for both control circuits and inductive loads, while ferrule-end connections and silver-plated pins improve contact reliability and ease field replacement. Non-indicating design minimizes false status signals, and the standard, compact footprint fits tight panel spaces without sacrificing performance. The stated “Superior overload and cycling capabilities” feature translates into longer cycle life and fewer replacements in demanding production lines. Compliance to CE Marked standards provides confidence for European installations and cross-border sourcing while maintaining compatibility with Eaton Bussmann series devices.

FAQs
To install the FNA-1-1/8, power down all equipment and verify that the circuit is de-energized. Use ferrule-end crimp connectors compatible with the ferrule-terminal design, slide the fuse into the appropriate fuse holder, and crimp or secure the ferrules per manufacturer guidance. Confirm correct polarity and seating, then restore power and perform a functional check to ensure the circuit engages without nuisance trips.
The FNA-1-1/8 is optimized for inductive and electronic loads common in control panels, such as motor starters, transformers, and power supplies. Its time-delay characteristic accommodates initial surge currents, reducing nuisance trips during startup, while maintaining robust protection during steady-state operation. This makes it ideal for mixed-load panels found in automation and process control environments.
Key ratings include a 1.125 A amperage rating and a 250 V voltage rating. Its interrupt capability is 10 kAIC at 125 Vac and 200 kAIC at 250 Vac, providing strong short-circuit protection for standard control circuits while supporting higher fault currents typical in industrial equipment. These specs help meet common safety and performance requirements for automated systems.
Yes, the FNA-1-1/8 is CE marked, indicating conformity with applicable European safety, health, and environmental protection directives. This certification supports regulatory acceptance across EU member states and aligns with common procurement expectations for electrical protection devices used in European installations and multi-site deployments.
The dual-element time-delay design reduces nuisance trips and allows smoother cycling, which translates to less unplanned downtime and longer equipment life. Silver-plated contacts improve reliability, lowering replacement frequency and maintenance costs. Although initial procurement may be higher than non-time-delay fuses, the reduced downtime and longer service intervals typically yield a favorable ROI in high-demand automation environments.
