Eaton FRS-R-20ID Fuse - RK5 Class, 200 kAIC at 600 Vac
Part Number: FRS-R-20ID
Quick Summary
The Eaton FRS-R-20ID fuse is a time-delay, dual-element protective device used in industrial control panels and motor circuits. Engineers often struggle with nuisance trips during inrush and startup surges, which can halt production and complicate maintenance schedules. The device is CE marked and RoHS compliant, aligning with widely adopted regulatory standards for electrical protection. Built as a Class RK5 fuse rated for 600 Vac, it delivers current limiting with reliable interruption while staying compatible with Bussmann series components. This combination delivers improved equipment protection, easier procurement, and lower total cost of ownership in modern panel assemblies. Its 20 A rating and 5 in length support flexible panel layouts and quick swaps.

FAQs
FRS-R-20ID is designed for RK5-compatible assemblies and uses ferrule end x ferrule end contacts. It fits standard 5 inch RK5 holders, with a body width and height of 0.81 inches. Ensure the panel cutout accommodates the 0.81 inch footprint and follow manufacturer torque and conductor sizing guidelines to preserve interrupting performance. For indicating variants, verify presence of the status indicator during commissioning.
The fuse provides 20 A operation with 600 Vac rating and a 200 kAIC interrupting capability at 600 Vac, delivering fast disruption of faults while tolerating startup inrush. Its time-delay design allows up to 10 seconds of response at 500% overload, reducing nuisance trips in motor starts and conveyor drives while safeguarding downstream circuits.
Yes. The FRS-R-20ID combines RK5 class protection, dual-element time-delay behavior, and 600 Vac capability, making it well suited for motor starters, drives, and conveyors that experience short surges. Its current-limiting action protects both power feeds and connected equipment, while ferrule-term connections simplify replacement and upgrades in existing Bussmann RK5 panels.
The FRS-R-20ID carries CE marking and RoHS compliance, ensuring alignment with European and global regulatory requirements for electrical protection devices. While it does not list SIL certification, it adheres to standard industry practices for RK5 fuses in industrial control applications, supporting safe and compliant operation across international installations.
Using the FRS-R-20ID can lower maintenance costs by reducing nuisance trips and enabling quick replacements in RK5 panels. The indicating version improves fault diagnosis, while the robust 200 kAIC interrupt capacity and CE/RoHS compliance support longer service intervals and faster repairs, delivering a favorable return on investment through higher uptime and streamlined procurement.
