Eaton KTS-R-50 Fuse - 200 kAIC at 600 Vac RK1 Class
Part Number: KTS-R-50
Quick Summary
The KTS-R-50 fuse by Eaton is a fast-acting Class RK1 current-limiting device for protecting motor drives and distribution panels. Engineers often face nuisance tripping and unplanned downtime when protection devices aren’t fast or selective enough. CE Marked compliance and a Class RK1 designation support standardization across global plants, while the 200 kAIC interrupt rating at 600 Vac enables robust protection in high fault-current environments. This solution delivers reliable protection with ferrule-end terminations and a compact form factor, translating to easier procurement, faster installation, and improved total cost of ownership for industrial facilities.

FAQs
The KTS-R-50 is ideal for motor drives, control panels, and power distribution setups in industrial environments. With a 50 A rating and 200 kAIC interrupt capability at 600 Vac, it provides fast protection for high-current circuits and helps minimize downtime by preventing damage to upstream components.
The 200 kAIC interrupt rating means the fuse can safely interrupt extremely high fault currents, limiting energy and arc duration. This reduces collateral damage, protects downstream equipment, and improves overall system reliability in applications such as MCCs and heavy industrial feeders.
Yes. The KTS-R-50 uses ferrule-end x ferrule-end connections and is rated for 600 V systems. This combination simplifies installation, ensures secure terminations, and supports quick field replacements in panels and control cabinets.
The KTS-R-50 is CE Marked, aligning with essential safety and performance standards. This certification facilitates global deployment and regulatory acceptance, enabling engineers to meet compliance requirements across multiple sites without redesigns or additional approvals.
When replacing fuses, verify the 50 A rating and 200 kAIC interrupt capacity match system fault currents. Use ferrule-end terminations for reliable connections, ensure the device fits within the 5.5 in length and 1.5 in width space, and confirm the enclosure supports 600 Vac operation and Class RK1 protection.
