Eaton FRN-R-35ID Time-Delay Fuse - Class RK5 CE Marked
Part Number: FRN-R-35ID
Quick Summary
The Eaton FRN-R-35ID time-delay fuse protects motor and control circuits in industrial power-distribution panels. Engineers often face nuisance trips during startup and unplanned downtime, driving maintenance costs. This device is CE marked and built to Class RK5 standards, with a finger-safe design and an indicator option. For OEMs and maintenance teams, the 3 in length, ferrule-end connections, and current-limiting performance translate to easier installation, faster service, and lower lifecycle costs. With a 35 A rating and robust interrupt capability, it accommodates common inrush in drives and contactors without nuisance outages. Plus, the dual-element design offers reliable protection with quick response times, minimizing arc-flash risk and protecting downstream equipment.

FAQs
The FRN-R-35ID uses ferrule-end connections compatible with standard RK5 fuse holders. Ensure enclosure clearance is sufficient for a 3 in length device, align ferrules with the holder terminals, and insert until seated. Verify the indicator (if equipped) shows the intended status after installation.
Its time-delay, dual-element design tolerates startup surges without nuisance trips. The 35 A rating paired with high interrupt ratings (200 kAIC at 250 Vac; 20 kAIC at 125 Vdc) provides dependable protection for motor drives and associated circuits during inrush events.
Yes. The FRN-R-35ID is rated for 250 Vac and 125 Vdc, with an interrupt capability of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, making it suitable for mixed AC and DC control panels and feeders.
The fuse is CE marked and belongs to the Class RK5 family, aligning with CE regulatory expectations for industrial protection devices and RK5-type protection standards used in branch-circuit fusing.
With options for fuse indication, easier fault identification reduces downtime. The robust inrush handling and high interrupt ratings protect circuits, potentially lowering replacement costs and extending equipment uptime in high-demand applications.
