Eaton FRS-R-7 Fuse - 200 kAIC at 600 Vac
Part Number: FRS-R-7
Quick Summary
The Eaton Bussmann series FRS-R fuse protects electrical circuits with time-delay, dual-element accuracy for motor drives and control panels. Engineers often battle nuisance trips and inconsistent protection, which drives downtime and maintenance costs. This part offers CE Marked compliance, Class RK5 designation, and voltage ratings of 600 Vac / 300 Vdc with a 200 kAIC interrupt at 600 Vac. Its ferrule-end connections and compact 5 in length simplify installation in standard panels while delivering reliable current limiting. Combined, these attributes reduce downtime, extend component life, and improve return on investment for automation projects. This makes it a practical choice for motor control, power distribution, and control circuits across manufacturing and process environments.

FAQs
The FRS-R-7 uses ferrule-end connections on both ends, designed for quick, reliable insertion into standard panel terminations. Its compact 5 inch length and 0.81 inch width/height support retrofit into existing enclosures and new builds alike, reducing installation time and avoiding modification of field wiring.
The fuse is rated 7 A with a time-delay, dual-element design and an interrupt rating of 200 kAIC at 600 Vac (and 20 kAIC at 300 Vdc). These specs translate to robust short-circuit protection for motor loads and feeders while allowing brief inrush events typical in automation systems without immediate tripping.
Yes. Its Class RK5 designation, current-limiting capability, and high voltage rating make it well-suited for motor control centers, feeders, and control panels in industrial automation environments where reliable protection and fast fault clearing are critical to uptime.
The FRS-R-7 is CE Marked, aligning with European safety and compliance requirements. Its RK5 class and current-limiting performance provide regulatory confidence for panel builders and integrators, supporting compliant deployment in automation projects.
The time-delay, dual-element design reduces nuisance trips during startup, lowering unplanned downtime. Its reliable protection extends upstream component life, and the ferrule-end design simplifies replacement, contributing to lower maintenance costs and faster repair cycles in ongoing production environments.
