Eaton KTN-R-10 Fuse - Class RK1, 200 kA at 250 Vac
Part Number: KTN-R-10
Quick Summary
KTN-R-10 fuse by Eaton provides fast-acting, current-limiting protection for control panels and motor circuits. In busy automation environments, nuisance fuse blows and downtime drain productivity, so choosing a proven protector matters. While the data set notes no explicit CE or IP marks, the device uses Class RK1 construction and delivers a robust 200 kA interrupting rating at 250 V, ensuring rapid fault clearance in demanding applications. This fuse's ferrule-end connections and 70/30 brass end caps simplify field termination, reducing installation time and wiring errors. The combination of compact form, reliable performance, and standardized Bussmann series compatibility supports streamlined procurement and easier maintenance for panel builders and OEMs.

Bussmann series KTN-R 250 V Class R fuse data sheet no. 1043
Fast-acting current-limiting design reduces fault energy quickly, protecting downstream circuits and sensitive electronics, which translates to longer component life and fewer nuisance trips in machine control panels and conveyors. This leads to improved line uptime and safer fault isolation in automated packaging and packaging-line equipment. The 10 A, 250 V rating paired with a 200 kA interrupting capability ensures reliable performance in high-energy fault events, minimizing collateral damage and extending equipment life in servo-driven applications. Ferrule-end x ferrule-end construction with 70/30 brass end caps provides robust terminations that resist vibration and arcing, enabling faster installation and reduced warranty costs in harsh manufacturing environments. Compatibility with the Bussmann RK1 family supports scalable procurement and consistent protection across control architectures, while the non-indicating design keeps panel aesthetics clean and maintenance simple. This design also addresses common objections about replacement timing by offering a standard, stockable device that fits common RK1 form factors for quick swaps.

FAQs
KTN-R-10 uses ferrule end x ferrule end connections with 70/30 brass end caps, delivering robust terminations that resist vibration and provide reliable electrical contact in industrial panels. This standard configuration simplifies field wiring and aligns with the Bussmann RK1 form factor for easy replacement.
Key specs are a 10 A amperage rating, 250 V voltage rating, and a 200 kA interrupting rating at 250 Vac. As a fast-acting, current-limiting fuse, it clears faults quickly to protect downstream equipment such as controls, relays, and motor drives, reducing damage and downtime.
The provided data does not list explicit compliance marks like CE or RoHS. For regulatory alignment, refer to Eaton’s catalogs and the RoHS Search Tool in the downloads to verify compatibility with your regional requirements and system-level compliance standards.
With a single-element, non-indicating design, replacement is straightforward when a fault occurs or during routine maintenance. Match the amperage (10 A) and voltage (250 V) ratings, use the same RK1 form factor, and inspect ferrule terminations for corrosion or wear to minimize downtime during swaps.
The KTN-R-10 delivers rapid fault clearance with a high interrupting rating, reducing arc energy and protecting sensitive drive electronics. Its robust ferrule-end construction simplifies installation, lowers maintenance labor, and supports scalable procurement across RK1-based protection schemes, contributing to higher uptime and lower total cost of ownership in manufacturing lines.
