Eaton FRN-R-2-8/10 Fuse - RK5 Class Time-Delay
Part Number: FRN-R-2-8/10
Quick Summary
FRN-R-2-8/10 fuse is a dual-element, time-delay protection device ideal for small branch circuits in industrial control panels. Engineers often contend with nuisance trips and lengthy fuse-selection processes as panels evolve. This FRN-R fuse is CE-marked and Class RK5, with finger-safe construction and clearly defined interrupt ratings for reliable protection. The combination of a 2.8 A rating, 250 Vac / 125 Vdc capability, and ferrule-end connections supports safer, faster installation and easier stocking for maintenance teams. This is especially valuable in high-mix, low-volume environments where quick fuse changes minimize downtime. With its current-limiting behavior and robust interrupt ratings, it supports compliance with industry protection standards while simplifying procurement.

Bussmann series Fusetron FRN-R RK5 fuse data sheet for up to 60 amps No. 1019
Time-delay, dual-element design is a feature that tames inrush currents while providing short-circuit protection. This minimizes nuisance trips in motor-start or PLC power rails, reducing unplanned downtime. Ideal for industrial control panels and machine builders requiring reliable protection without sacrificing startup performance. With a 2.8A amperage rating, the FRN-R protects low-power logic and sensing circuits precisely, improving component life and maintenance planning. Use in small to mid-size automation panels to meet circuit-level protection requirements. Interrupt ratings of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc guarantee fast fault clearing even in high-energy mains, translating into safer equipment and reduced bus damage on automated conveyors and packaging lines. Ferrule-end connections and compact dimensions support easy retrofits and clean panel layouts, speeding installation and reducing field labor. CE marking and finger-safe housing meet modern electrical safety and European market requirements, simplifying procurement within Bussmann RK5 families. The fuse's standard packaging and compatibility with RK5 catalogs help stocking teams reduce inventory complexity and improve serviceability.

FAQs
Install the FRN-R-2-8/10 using the ferrule-end connections specified by Eaton Bussmann. Ensure the circuit amperage matches the 2.8 A rating and verify the panel's RK5-compatible fuse holder is correctly sized. Route wiring cleanly, secure ferrules, and check that the fuse sits fully seated to ensure proper interruption during fault events.
The FRN-R-2-8/10 is a dual-element, time-delay design with current-limiting capabilities. It handles inrush currents without nuisance trips while providing rapid fault clearance up to 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc. This combination supports reliable operation in motors, drives, and PLC power rails.
Yes. The FRN-R-2-8/10 is CE-marked, aligning with European market requirements. It features a Class RK5 designation and finger-safe construction, contributing to safer maintenance practices and compliance with typical electrical protection standards in industrial environments.
Absolutely. The FRN-R-2-8/10 uses ferrule-end x ferrule-end connections designed for reliable, repeatable terminations. This makes retrofits and replacements straightforward in RK5-compatible panels, reduces torque-related issues, and supports consistent electrical performance across installed fleets.
Choosing FRN-R-2-8/10 provides predictable protection with a known 2.8 A rating, high interrupt ratings, and time-delay behavior that minimizes downtime due to nuisance trips. It also aligns with RK5 family inventories, simplifies procurement, and speeds maintenance in automation environments, delivering a favorable return on investment through improved uptime and safer servicing.
