Eaton FRS-R-6-1/4 Fuse - Class RK5, 600 Vac CE Marked
Part Number: FRS-R-6-1/4
Quick Summary
The Eaton FRS-R-6-1/4 fuse protects industrial control and motor circuits with time-delay, current-limiting performance. Engineers often battle nuisance trips during inrush events, risking downtime—this dual-element RK5 fuse helps distinguish between transient surges and real faults. CE marking confirms compliance with European safety standards, and the RK5 class designation aligns with common protection schemes in industrial panels, while the ferrule-ended construction supports fast, reliable installations. The non-indicating design simplifies replacement in standard fuse holders and reduces maintenance complexity. By combining robust interrupt ratings with a compact footprint, this fuse delivers dependable protection without demanding enclosure changes, supporting safer, more efficient panel and machine upgrades.

Time-delay, dual-element design provides selective protection, allowing inrush currents typical of motors and transformers to ride through briefly and reducing nuisance trips. Business impact: less downtime and smoother startup sequences in automated lines; application: motor feeders and control circuits. Class RK5 current-limiting fuse ensures fast fault clearing while maintaining coordination with upstream protection, improving system reliability. Impact: enhanced safety margins and reduced arc-flash exposure in panels; application: machine control enclosures and distribution panels. High interrupt rating of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc protects high-energy equipment from damaging faults, enabling safer operation in heavy industries. Impact: greater system resilience; application: power distribution to industrial equipment. Ferrule end x ferrule end and non-indicating design simplify field replacement and retrofit in standard Bussmann–Eaton installations. Impact: faster maintenance and reduced labor costs; application: retrofit projects and new builds. FDA-compliant packaging considerations? Not applicable here; instead, CE marked and standard footprint support quick adoption across Eaton Bussmann series installations. Impact: reduced downtime and streamlined procurement for panel builders and OEMs. The compact 5 in length with 0.81 in width/height dimensions fits common fuse holders, easing enclosure design changes. Impact: smaller form factor lowers cabinet depth requirements and supports modular control architecture. Compliance and lifecycle benefits: CE Marked devices align with EU safety standards, and a standard packaging approach reduces stocking complexity for distributors and integrators. Impact: improved supply chain efficiency and faster project timelines.

FAQs
Install the FRS-R-6-1/4 with ferrule ends into compatible RK5 fuse holders in control panels or MCCs. Ensure correct orientation, seating, and secure ferrule termination. Verify 600 Vac/300 Vdc rating matches system voltage, and confirm the interruption rating aligns with your fault current. Replacement is straightforward due to the non-indicating design and standardized 5 in length.
The fuse provides a 6.25 A amperage rating, rated for 600 Vac and 300 Vdc, with 200 kAIC interrupt at 600 Vac and 20 kAIC at 300 Vdc. It’s a time-delay, dual-element RK5 device, allowing brief overloads to pass without tripping while still delivering fast fault clearance—ideal for motors and control circuits.
Yes. Its time-delay, dual-element design and Class RK5 protection make it well-suited for motor control centers and MCC feeders. The 5 in length and ferrule-terminals support standard panel configurations, while the high interrupt rating helps protect upstream gear during fault events, reducing downtime and equipment damage.
The FRS-R-6-1/4 is CE marked, signaling compliance with applicable European safety requirements. It is designed as a Class RK5 protection device for industrial applications, aligning with common protection schemes in European and global industrial installations.
With a non-indicating design, visual fault indication requires testing equipment or panel indicators. The 5 in length, ferrule ends, and standard packaging simplify stocking and replacement, reducing downtime during maintenance. The robust interrupt ratings and time-delay protection also improve uptime, lowering total cost of ownership by minimizing nuisance trips and unscheduled outages.
