Eaton FRN-R-9 fuse - RK5 Class Time-Delay CE Marked
Part Number: FRN-R-9
Quick Summary
Eaton FRN-R-9 fuse protects control panels and motor circuits with time-delay, dual-element protection. This design helps prevent nuisance trips during motor start-up and inrush events common in industrial environments. CE marking and RoHS considerations ensure compliance with EU safety standards, while the Bussmann RK5 family delivers reliable coordination with other protective devices. Dual-element current-limiting action balances fast response to faults with tolerance for startup surges, helping extend equipment life and reduce downtime. By selecting this fuse, engineers gain predictable protection, easier field replacement in standard RK5 assemblies, and a path toward more consistent maintenance planning and lifecycle cost control. This combination is well-suited for OEMs, integrators, and maintenance teams seeking dependable protection with straightforward sourcing.

FAQs
Yes. The FRN-R-9 is designed for RK5 fuse blocks and uses ferrule end connections, allowing plug‑in replacement in compatible assemblies. With a 2 in length and a compact 0.56 in by 0.56 in footprint, it fits standard Bussmann RK5 configurations. When installing, confirm the block supports ferrule-ended fuses, observe clearance requirements, and follow lockout-tagout procedures during service.
FRN-R-9 provides a 9 A amperage rating with a voltage rating of 250 Vac and 125 Vdc. It is a time-delay, dual-element, current-limiting fuse with a stated response of 8 seconds at 500% overload. Interrupt ratings are 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, offering robust protection for motors and power circuits in industrial systems.
Yes. FRN-R-9 is designed for motor protection in control panels, drives, and branch circuits. Its time-delay capability accommodates inrush currents typical of motor starts, while its high interrupt rating preserves upstream devices. For selective coordination, pair FRN-R-9 with other RK5 devices to optimize reliability and minimize nuisance outages in complex protection schemes.
The FRN-R-9 is CE labeled, indicating conformity with applicable European safety standards. While the data confirms CE marking, RoHS compliance is supported by Eaton’s compliance tools; you can verify via the RoHS Search Tool. This helps ensure regulatory alignment for EU markets and restricted-substance requirements in your supply chain.
The dual-element, time-delay design reduces nuisance trips and extends fuse life by matching fault currents with startup surges. Its compact form and ferrule terminals enable quick replacement, lowering maintenance time. Over the lifecycle, fewer interruptions translate to higher equipment availability, lower downtime, and improved total cost of ownership for automation projects.
