Eaton FRN-R-6 Fuse - RK5 Time-Delay, 6 A 200 kAIC
Part Number: FRN-R-6
Quick Summary
The Eaton FRN-R-6 fuse provides fast-acting protection for motor starters and control circuits in industrial equipment. Nuisance trips and unplanned downtime in harsh industrial environments can erode productivity and raise maintenance costs. CE marking confirms compliance, RoHS readiness supports sustainability, and the RK5 family provides reliable coordination for industrial protection schemes. From compact form factors to standard ferrule end connections, this fuse balances installation simplicity with rigorous protection. This translates to lower total cost of ownership through durable construction, predictable tripping behavior, and straightforward field replacement. Engineers appreciate the time-delay response for motor inrush and the dual-element design that minimizes nuisance trips while protecting circuits.

FAQs
FRN-R-6 is designed for standard RK5 fuse blocks and ferrule-end terminations. It fits Bussmann RK5 panels and enclosures, enabling quick drop-in replacement without rewiring. The non-indicating design simplifies subsystem wiring while preserving reliable protection in automation cabinets. Always confirm housing acceptance and torque recommendations from Eaton data sheets for best results.
FRN-R-6 is rated at 6 A with an interrupt capacity of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc. It features a time-delay, dual-element design and responds in approximately 8 seconds at 500% overload, providing selective protection for motors and control circuits while tolerating inrush. The device is CE-marked and suitable for standard industrial supply rails.
This fuse is well suited for motor starters, conveyors, automated packaging lines, and general automation panels where inrush tolerance and reliable protection are essential. Its RK5 class and ferrule-end termination simplify cabinet design and maintenance in manufacturing, process control, and material handling environments, delivering predictable performance under fault conditions.
The FRN-R-6 carries CE marking and aligns with RoHS compliance expectations through Eaton's RoHS resources. These certifications support regulatory qualification for European installations and sustainability targets. Use the RoHS search tool for verification, and reference the Bussmann RK5 data sheets for installation guidance and product lineage within protected automation architectures.
By combining time-delay protection with a robust 6 A rating and high interrupt capacity, FRN-R-6 reduces nuisance tripping while safeguarding downstream equipment. Its compact form factor and ferrule-end connections shorten installation time and spare-part handling in serviceable automation cabinets, contributing to lower downtime, easier field replacement, and favorable total cost of ownership in mid- to high-availability systems.
