Eaton KTS-R-3 Fuse - Class RK1, 200 kAIC @ 600V
Part Number: KTS-R-3
Quick Summary
The Eaton Bussmann KTS-R-3 fuse provides fast-acting overcurrent protection for industrial control panels and motor circuits. Engineers often struggle with nuisance tripping, limited selectivity, and compatibility when sizing fuses for high-energy systems. CE Marked and designed as a Class RK1 current-limiting fuse, it delivers reliable protection with a 600 V rating and a 200 kAIC interrupt capability. With ferrule-end connections and a compact 0.8 in depth, this 3 A device fits standard industrial enclosures while minimizing space impact and installation time. For panel builders and machine integrators, the KTS-R-3 reduces total cost of ownership through predictable performance and easy sourcing from Eaton Bussmann catalogs and compatible Bussmann series components.

Feature → Business Impact → Application: Fast-acting, current-limiting Class RK1 fuse minimizes arc energy during faults, protecting conductors and downstream electronics while enabling faster downstream troubleshooting in control panels and motor circuits. This translates to reduced downtime and lower replacement costs in manufacturing lines and packaging machines. Feature → Business Impact → Application: An interrupt rating of 200 kAIC at 600 V allows safe interruption of high fault currents common in industrial feeders, increasing system reliability and improving workflow continuity in OEM assemblies and distribution panels. Feature → Business Impact → Application: Ferrule end x ferrule end connections provide quick, secure wiring terminations, simplifying field installation, improving contact integrity, and reducing commissioning time in new builds or retrofits. Feature → Business Impact → Application: Melamine glass tube construction offers robust thermal and chemical resistance, delivering longer fuse life in harsh environments such as washdown areas or dusty industrial spaces, supporting a lower total cost of ownership. Feature → Business Impact → Application: CE marking and compliance with RK1 standards offer confidence for global projects and route-to-market; users can rely on standardization across Eaton Bussmann products, easing procurement and maintenance. Feature → Business Impact → Application: Compact dimensions—0.8 in width/depth and 5 in height—facilitate installation in tight panels and compact control enclosures, enabling more efficient panel layouts and better space utilization in machine builds.
