Eaton FRS-R-9 Fuse - Class RK5, 200 kAIC CE Marked
Part Number: FRS-R-9
Quick Summary
Eaton FRS-R-9 fuse provides time-delay, dual-element overcurrent protection for electrical distributions and motor circuits. Nuisance tripping and slow response on mixed loads often disrupt production and complicate protection coordination. As part of the CE-marked RK5 family, the device aligns with European safety requirements and RoHS considerations, while offering reliable protection in a compact form factor. For panel builders and OEMs, the 5 in length and ferrule-end termination simplify installation and serviceability. With a 9 A rating and high interrupt capabilities, it supports safe, durable operation in industrial control applications.

Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Feature: Time-delay, dual-element, current-limiting design; Business Impact: Allows inrush tolerance and selective fault clearing, reducing outages and protecting conductors during startup surges; Application: motor starters, conveyor drives, and PLC power rails, with keywords like time-delay fuse for motor protection and dual-element current-limiting RK5 usage. Paragraph two highlights Class RK5 compatibility and 9 A rating, enabling broad AC/DC compatibility in control panels and machine feeds, addressing installation lead times. Paragraph three emphasizes an interrupt rating of 200 kAIC at 600 Vac, meaning robust fault handling in high-energy environments and safer shutdown sequences for panel boards. Paragraph four describes ferrule end x ferrule end connections in a compact 5 in package; the non-indicating design simplifies diagnostics in crowded enclosures and speeds field replacement. Paragraph five notes CE marking and RoHS considerations, helping ensure regulatory compliance during procurement and reducing vendor risk in European projects.

FAQs
The FRS-R-9 is intended for control panels and motor protection in 600 Vac circuits. Its time-delay, dual-element design tolerates inrush while providing fast fault clearing. Use in applications with Class RK5 protection and ferrule-end terminations to ensure reliable coordination and ease of installation in industrial control panels.
The time-delay characteristic accommodates inrush currents typical of motor startup, allowing the fuse to withstand brief surges without tripping. This reduces nuisance trips, preserves motor life, and improves system uptime while still delivering fast fault clearance under sustained overloads.
FRS-R-9 is rated at 9 A with an interrupt rating of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc. It supports a 600 Vac / 300 Vdc voltage rating and a dual-element, current-limiting design, making it suitable for mixed AC/DC protection in industrial equipment.
Yes. The fuse uses ferrule end to ferrule end connections and comes in a compact 5 in length with a 0.81 in width and 0.81 in height. Its non-indicating design supports easy replacement in crowded panels, while maintaining robust mechanical fit and electrical reliability.
Install in compliant equipment enclosures designed for RK5-class fuses, verify the 9 A rating matches the circuit design, ensure proper ferrule-termination hardware, and confirm CE-marked status for regulatory alignment. Consider panel space, heat dissipation, and protective coordinate with upstream fuse sizing to optimize protection without nuisance trips.
