Eaton FRS-R-3 Fuse - Class RK5, 600 Vac CE Marked
Part Number: FRS-R-3
Quick Summary
FRS-R fuse provides time-delay, current-limiting protection for electrical panels and machines in industrial environments. Designers often face nuisance trips and unplanned downtime when protection is undersized or mismatched; the FRS-R offers predictable coordination with downstream devices and fast clearing to minimize outages. It’s CE marked for European compliance and RoHS compliant, with Class RK5 designation signaling a validated protection class for Bussmann Series installations. This combination delivers reliable sensing, easier sourcing, and reduced maintenance costs in control cabinets, motor starters, and power distribution panels. Use with standard ferrule-end terminations simplifies wiring and reduces field installation time while maintaining compliance and traceability in harsh environments.

Bussmann series Fuseology
Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Time-delay, dual-element design provides inrush tolerance while maintaining fast fault clearance, improving protection coordination and reducing unnecessary outages in conveyors, pumps, and automated machinery. This translates to improved equipment longevity and lower maintenance costs for critical processes. A 3 A amperage rating enables precise protection for smaller control circuits, enabling compact panel layouts and optimized wiring. With an interrupt rating of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc, the FRS-R-3 delivers robust short-circuit protection in demanding automation environments, minimizing arc-flash risk and downstream damage. Ferrule end-to-end connections offer secure terminations, accelerating installation and simplifying field service, while the non-indicating design keeps front panels clean for easier diagnostics. At 5 in length, 0.81 in width and height, and 0.14 lb weight, the fuse fits tight panels and standard stock, reducing spare parts inventory. CE marking and RoHS compliance support global deployments and regulatory alignment for the Bussmann Series.
