Time-delay, dual-element design reduces nuisance trips during startup and transient events, improving equipment uptime. This design minimizes false trips on inrush currents common in motor control circuits, enhancing reliability in automated lines. 1.6 A rating with 250 Vac and 125 Vdc compatibility provides selective protection for low-current control circuits without sacrificing safety margins. The dual-element fuse clamps fast fault currents while allowing temporary inrush, helping stay within wiring and enclosure limits. High interrupt ratings of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc give robust fault protection in cabinet distributions and machine panels, ensuring rapid clearance of faults in harsh environments. Class RK5 architecture and ferrule-end connections ensure easy replacement and standardized installation across Eaton Bussmann series, enabling quick swaps in shared fuse holders and reducing downtime. The non-indicating design minimizes panel clutter and simplifies servicing in dense control enclosures. Compact form factor (2.1 in length, 0.54 in width) supports dense layouts while maintaining compatibility with standard RK5 footprints, contributing to streamlined procurement, consistent performance, and reliable automation protection across OEM and end-user installations.

FAQs
The FRN-R-1-6/10 is designed for Eaton Bussmann RK5 fuse holders with ferrule-end terminations, matching standard RK5 footprints used in control panels and motor drives. Its 2.1 inch length and 0.54 inch width fit in common RK5 sockets, enabling quick swaps and minimal downtime during maintenance or panel refreshes.
This fuse is rated 1.6 A with voltage ratings of 250 Vac and 125 Vdc. It provides time-delay, dual-element protection and has interrupt ratings of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, making it suitable for applications with inrush currents and short-circuit events in industrial equipment.
Yes. The time-delay, dual-element design is specifically intended to tolerate short inrush currents common in motor starters and automation gear, while still providing rapid fault clearing during sustained faults. This balance helps protect wiring and devices without nuisance tripping during normal startup transients.
The FRN-R-1-6/10 is CE marked, aligning with European safety and environmental requirements. While RoHS compliance is not explicitly listed in the data, users can verify through Eaton’s RoHS search tool linked in the product resources, ensuring compliance for regulated assemblies and markets.
Installation benefits include quick swaps due to ferrule-end connections and RK5 compatibility, reducing commissioning time. Maintenance gains come from reduced nuisance trips and longer load life thanks to time-delay protection. The device’s compact form factor, standard packaging, and clear interchangeability also lower spares costs and simplify panel refresh cycles.
