Eaton FRN-R-3-2/10 fuse - CE Marked
Part Number: FRN-R-3-2/10
Quick Summary
With the Eaton FRN-R fuse, you get reliable overcurrent protection for control panels and power distribution systems. Engineers often struggle with nuisance trips during startup or protection that doesn't align with panel design. This Class RK5, time-delay, dual-element device delivers consistent fault clearance up to 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, with CE marking for global compliance. Its non-indicating, finger-safe design simplifies installation in crowded control cabinets, while ferrule-end connections speed wiring and reduce field adjustment. For manufacturers and integrators, this fuse helps optimize uptime and safety while aligning with low-voltage protection standards.

Feature → Business Impact → Application: The FRN-R is a time-delay, dual-element, current-limiting fuse that tolerates short surges without nuisance tripping, reducing downtime and false alarms in control circuits. This translates to improved machine availability and safer startup sequences in automation panels. Application: Ideal for power distribution in control cabinets and machine-builds where reliable inrush handling is essential. Feature → Business Impact → Application: Class RK5 construction standardizes protection across modular assemblies, enabling consistent maintenance practices and easier spares management in manufacturing environments. Application: Suitable for motor control centers and feeder circuits that require repeatable protection with minimal replacement cycles. Feature → Business Impact → Application: Ferrule-end x ferrule-end connections provide quick, robust wiring and repeatable terminations, cutting commissioning time and improving vibration resistance in field installations. Application: Panel builders benefit from faster assembly and dependable electrical integrity in harsh environments. Feature → Business Impact → Application: 3 in length with compact footprint fits tight enclosures, freeing panel space and enabling higher component density without compromising protection. Application: Electronics enclosures and compact control panels in robotics and packaging lines. Feature → Business Impact → Application: Interruption ratings of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc deliver strong fault protection for high-energy lines, helping meet safety and reliability targets. Application: feeders, drives, and power circuits that demand robust downstream protection. Feature → Business Impact → Application: Non-indicating design reduces maintenance checks while finger-safe features enhance operator safety during inspections. Application: routine service in automated lines where visual fuse status is not required but reliability is critical. Finally, compliance and packaging considerations—standard packaging and CE compliance simplify procurement and integration for global projects.

FAQs
For FRN-R-3-2/10, ensure ferrule-end conductors are within the fuse’s recommended torque specifications and wire sizes. Use ferrule-end terminals to maintain secure, vibration-resistant terminations in control panels. Confirm alignment with EQ and panel layout to avoid clearance issues and ensure consistent replacement intervals during scheduled maintenance.
The FRN-R-3-2/10 provides an interrupt rating of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, with a reported response time of 8 seconds at 500% overload. These figures support fast fault clearance while tolerating normal inrush, making it suitable for control circuits and discrete machine protections.
Yes. With time-delay, dual-element construction and RK5 class, the FRN-R-3-2/10 handles short surges common in motor starting without nuisance tripping. Its current-limiting features help limit arc-flash risk and protect downstream electronics, while still providing rapid clearance under fault conditions.
The FRN-R-3-2/10 is CE marked, indicating conformity with applicable European safety and performance requirements. It is designed for standard RK5 protection in low-voltage circuits and aligns with typical European electrical protection norms used in control panels and machine builds.
FRN-R’s reliable time-delay protection reduces nuisance trips, lowering unplanned downtime. Its finger-safe design and ferrule-end connections simplify installation and maintenance, cutting commissioning time and spare-part stocking. Over the lifecycle, these factors translate to improved line throughput, safer operation, and a lower total cost of ownership.
