Eaton FRN-R-2-1/2 Fuse - 200 kAIC at 250 VAC
Part Number: FRN-R-2-1/2
Quick Summary
The Eaton FRN-R-2-1/2 fuse provides time-delay, dual-element protection for industrial control circuits. Sourcing reliable protection for inrush-prone loads can trigger nuisance trips and increase downtime. CE-marked with RK5 class and industry-standard ferrule ends, this fuse aligns with global panels and safety requirements. In practice, engineers achieve improved uptime and predictable protection for motor drives and control circuits by using this device. Its 2.5 A rating, 250 VAC/125 VDC capability, and 200 kAIC interrupt rating make it suitable for applications from small power supplies to machine safety circuits. This helps procurement by reducing part numbers while maintaining compliance and performance in control panels.

Time-delay, dual-element design delivers gradual current limiting, so startup surges are tolerated and nuisance trips decrease. This translates to fewer unnecessary shutdowns and longer equipment uptime, especially in motor drives and solenoid-heavy loads. Use in standard control panels and machine power feeds. High interrupt rating of 200 kAIC at 250 VAC with a 2.5 A rating ensures fast fault clearing while protecting downstream components. Improved panel protection and reduced downstream damage; application in small power circuits and feeder lines in automation cabinets. Ferrule-end x ferrule-end connections simplify installation with common wiring practices; no indicator reduces panel clutter and simplifies replacement in tight spaces. Ease of maintenance and quick swaps support retrofit or new builds in machine and line protection. Class RK5 designation and CE marking support regulatory alignment for panel builders; standard packaging simplifies stocking and replacement in multi-site deployments. Compact 3 in length and 0.81 in width/height with a 1.95 lb weight fits in constrained enclosures, enabling flexible layouts in control cabinets. Compatibility with Bussmann series data and RoHS-compliant supply chains helps ensure a cohesive protection strategy across automation systems.

FAQs
FRN-R-2-1/2 installations should align with ferrule-end wiring practices and use standard RK5 fuse slots. Verify circuit amperage is 2.5 A and ensure wiring complies with 250 VAC or 125 VDC ratings. The non-indicating design minimizes visual clutter, and the 3 inch length fits typical enclosure spaces while preserving accessibility for maintenance.
The time-delay, dual-element design tolerates startup surges, reducing nuisance trips while still delivering robust fault protection. The datasheet notes a response time of 8 seconds at 500% overload, enabling reliable operation for motor drives and actuated loads without sacrificing protection during fault events.
Yes, the FRN-R-2-1/2 is CE marked, aligning with international panel standards and simplifying multi-region procurement. For RoHS considerations, Eaton provides access to RoHS tooling to verify compliance; confirm local regulatory requirements and ensure the rest of the protection scheme meets those rules.
Ideal for low-to-medium power control circuits, small motor drives, and machine control feeders, the FRN-R-2-1/2 offers reliable protection in standard automation cabinets. Its RK5 class and ferrule-end connections support consistent protection strategy across a fleet of panels, reducing stocking complexity and enabling scalable protection across lines.
ROI stems from reduced nuisance trips, lower maintenance costs, and longer equipment life due to a robust 200 kAIC interrupt rating at 250 VAC. Although initial cost may be higher, the fuse delivers greater uptime, fewer replacement cycles for power feeds, and improved resilience in automated production lines, delivering lower total cost of ownership over time.
