Eaton KTK-R-10 Fuse - Class CC, UL Listed
Part Number: KTK-R-10
Quick Summary
KTK-R-10 fuse is a fast-acting current-limiting device for industrial control panels. It delivers reliable protection where space is limited and high fault currents are possible. Engineers frequently contend with nuisance trips and limited interrupt ratings; the KTK-R-10 helps by combining a dual-element design with a rugged rejection-style construction. This fuse carries UL Listed, CSA Certified, CE Marked and RoHS Compliant certifications, supporting global compliance. In practice, it enables safer, more efficient power distribution while simplifying spare-part inventories and maintenance planning for lighting, motors, and capacitive loads.

FAQs
The KTK-R-10 is a current-limiting, fast-acting Class CC fuse from Eaton’s Bussmann series. It is designed for industrial control panels, street lighting, general lighting, and distribution equipment. Its 10 A rating, dual-element design, and 200 kAIC interrupt rating support reliable protection in high-current environments while maintaining compact form factors and easy installation with ferrule ends.
Key specifications include a 10 A amperage rating, 600 V voltage rating, 200 kAIC interrupt rating, dual-element current-limiting design, Class CC classification, and non-indicating fuse indicators. It uses ferrule-end connections, has a 1.5 in length, 0.41 in width and height, and a weight of 0.18 lb. It is UL Listed, CSA Certified, CE Marked, and RoHS compliant.
KTK-R-10 offers reliable short-circuit protection with fast-acting current limitation, reducing conductor and component damage during faults. The rejection-style design minimizes wrong replacements, while ferrule-end connections speed installation. Its compact Class CC form factor fits crowded enclosures, and the 200 kAIC rating provides robust protection in high-inrush applications common to controls panels and distributed loads.
The KTK-R-10 is UL Listed, CSA Certified, and CE Marked, with RoHS compliance. These certifications verify safety, performance, and environmental compliance across North American and European markets, enabling global deployment in industrial facilities, lighting projects, and equipment with strict regulatory requirements.
By combining high interrupt capability with a compact, easy-to-install ferrule-end design, the KTK-R-10 reduces downtime during faults and simplifies maintenance logistics due to standardized spares. Its long-term reliability and regulatory compliance minimize troubleshooting time, extend device life, and lower total cost of ownership in manufacturing environments and power-distribution networks.
