Eaton FRS-R-600 Fuse - Class RK5, 600A, 200 kAIC
Part Number: FRS-R-600
Quick Summary
Eaton FRS-R-600 fuse is a time-delay, dual-element protection device designed for high-current branch circuits in industrial control panels. Engineers often face nuisance trips or outages during motor starts and load surges, which can drive up downtime and maintenance costs. This solution carries CE marking and RoHS compliance, aligning with common regulatory requirements, while Class RK5 coordination supports selective protection. With a 600 A rating and 200 kAIC interrupt capability at 600 Vac (and 20 kAIC at 300 Vdc), the FRS-R-600 integrates into Bussmann series installations, delivering reliability, predictable protection, and long-term cost reduction for feeders and motor circuits. Optimal for OEMs and retrofit projects seeking scalable protection across industrial power distribution.

Bussmann series Fuseology
Bussmann series FRS-R 600 V Class R 65-600 A fuse data sheet no. 1018
Time-delay, dual-element design delivers controlled response to inrush currents, reducing nuisance trips while maintaining robust short-circuit protection. This translates to fewer unplanned outages and lower maintenance costs in heavy-load lines. Ideal for motor starters, gear motors, conveyors, and feeders in process automation, where reliable protection during start-up and load changes is essential. High amperage rating and interrupt capability provide resilience for large circuits. With a 600 A amperage rating and 200 kAIC interrupt rating at 600 Vac (and 20 kAIC at 300 Vdc), the FRS-R-600 safeguards power distribution without excessive nuisance trips, enabling selective coordination in multi-fuse schemes. Users gain clearer fault isolation and faster restoration, minimizing downtime and extending equipment life in harsh industrial environments. RK5 Class and blade-end connections ensure compatibility with Bussmann series devices and standard panel layouts. Blade-end x blade-end connections support fast, tool-free replacement, while the 13.38 in length and 2.88 in width/height fit common enclosures. This simplifies installation, reduces field adjustments, and helps maintain consistent protective reach across installed bases. Non-indicating status reduces visual misreads, and the CE marking with RoHS compliance aligns with regulatory and environmental requirements. Standard packaging simplifies stocking and lifecycle management, and the fusion of time-delay characteristics with dual elements supports durability in fluctuating loads. For installers, the FRS-R-600 delivers predictable performance and compatibility with Eaton Bussmann full-line catalogs. Industry experience shows that selecting RK5 class fuses with appropriate interrupt ratings improves uptime and safety margins in industrial facilities.

FAQs
To install the FRS-R-600, power down the panel, inspect the blade-end contacts for cleanliness, and position the fuse so the blade-end connections engage fully in the holder. Align with the Bussmann RK5 footprint, replace with matching catalog number, and re-energize the circuit. Verify continuity and ensure proper panel labeling after installation.
The FRS-R-600 combines time-delay operation with a dual-element design, enabling reliable protection during motor inrush while limiting nuisance trips during steady-state overcurrents. With 600 A rating and 200 kAIC at 600 Vac, it supports selective coordination in feeders and motor circuits, reducing downtime and protecting downstream equipment from faults.
Yes, the FRS-R-600 is rated for 600 Vac and 300 Vdc. Its interrupt ratings are 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc, enabling robust fault interruption in both AC and DC portions of industrial power systems while maintaining safe operation and rapid fault isolation.
The FRS-R-600 is CE marked, indicating compliance with European safety standards. Eaton also references RoHS compliance for restricted substances. This combination supports regulatory alignment for many international installations and sustainability goals in modern facilities.
The FRS-R-600 offers reduced downtime through reliable time-delay protection that tolerates motor start-up surges and load changes, while preserving strong short-circuit protection. Its compatibility with the Bussmann series and standard dimensions lowers spare-parts inventory and maintenance effort, delivering faster replacements and improved system availability over the lifecycle of feeders and power distribution networks.
