FAQs
The FRS-R-6 uses ferrule end x ferrule end terminations and fits standard Bussmann-series panel assemblies. Mount in an appropriate enclosure with compatible bus bars, connect per the markings, and ensure cooling clearance. With a 5 in length and 0.81 in width/height, this fuse slots into typical RK5-compatible holders and supports straightforward replacement during maintenance.
FR S-R-6 offers a 6 A amperage rating and a 200 kAIC interrupt rating at 600 Vac, plus 20 kAIC at 300 Vdc. Its response time is 10 seconds at 500% overload. The device is a dual-element, time-delay fuse with a 600 Vac / 300 Vdc voltage rating, designed to tolerate inrush while protecting downstream circuits.
Yes. The FRS-R-6 is a dual-element, time-delay Class RK5 fuse rated for 6 A, making it well-suited for motor protection in panel boards and MCCs. Its high interrupt rating cushions the circuit during faults, while the time-delay feature accommodates motor inrush, reducing nuisance trips and improving uptime in automation installations.
The FRS-R-6 is CE Marked, aligning with European safety requirements for electrical protection products. While UL or IP-specific ratings are not listed in the provided data, CE compliance signals adherence to essential safety standards. Always verify local regulatory expectations for your installation and consult Eaton’s documentation for the latest certification details.
The FRS-R-6 delivers predictable protection with minimal nuisance trips, which lowers downtime and maintenance costs in high-demand lines. Its compact RK5 form factor simplifies retrofits, while the ferrule-terminal design reduces wiring time and returns on investment through faster service and longer asset life in industrial environments.
