Eaton FRN-R-6/10 Fuse - Class RK5, 250 VAC
Part Number: FRN-R-6/10
Quick Summary
FRN-R-6/10 is a time-delay, dual-element fuse used to protect industrial control panels. Nuisance trips during motor starts and inrush currents are a common pain point, and this design minimizes unplanned downtime. This Class RK5, CE-marked device delivers high fault protection with an interrupt rating up to 200 kAIC at 250 VAC and 20 kAIC at 125 VDC. For procurement and installation, the ferrule-end construction and 0.6 A rating provide reliable, compact protection for small control circuits while fitting standard fuse holders. Additionally, its time-delay characteristic helps manage motor inrush, reducing replacement and service costs.

FAQs
The FRN-R-6/10 is designed for standard Bussmann FRN-R / RK5 configurations with ferrule-end connections. It fits typical control-panel fuse holders and can be used in single- or multi-pole assemblies. For procurement, confirm ferrule size compatibility and ensure your panel supports Class RK5 fuses to maximize reliability and interchangeability.
This fuse features a 0.6 A amperage rating, a voltage rating of 250 VAC or 125 VDC, and dual-element, time-delay protection. It provides 200 kAIC interrupting capability at 250 VAC and 20 kAIC at 125 VDC, with a 8-second response time at 500% overload. These specs enable safe protection for both AC control circuits and DC loads.
Yes. The time-delay, dual-element design is well-suited for motor protection where inrush is common, reducing nuisance tripping while still interrupting damaging faults. Its high interrupt ratings support safe use in power distribution paths, and the ferrule-end construction enables durable, quick installations in control cabinets. Ensure the 0.6 A rating matches the protected circuit's requirements.
The FRN-R-6/10 is CE marked, indicating conformity with essential European safety, health, and environmental requirements. It belongs to the Class RK5 family, which is widely recognized for branch-circuit protection. While the data does not list additional certifications, CE compliance and the RK5 class designation support global applicability in industrial environments.
The time-delay design lowers the incidence of nuisance trips, reducing unplanned downtime and maintenance costs in systems with inrush currents. Its compact ferrule-end format simplifies replacement and stocking, leading to lower spare-part diversity and faster service. Over time, this translates to higher equipment uptime and improved total cost of ownership for panel builders and maintenance teams.
