Eaton KTS-R-275 Fuse - 200 kAIC Class RK1

275 A fast-acting, current-limiting protection is provided by the KTS-R-275, designed for high-demand motors and feeders. It interrupts fault currents quickly to limit arc energy and prevent damage to downstream equipment. The fuse is well suited for industrial power distribution and panel applications where reliable protection and minimal nuisance trips matter most, delivering measurable improvements in uptime and maintenance planning. With an interrupt rating of 200 kAIC at 600 V, the KTS-R-275 offers robust fault clearance for large motor loads and high-energy circuits, enabling safer maintenance and better protection coordination across complex systems. This capability supports selective coordination studies and reduces the likelihood of cascading outages during faults. Class RK1 with ferrule design ensures secure terminations in standard enclosures, while the rejection-style construction helps prevent mis-insertion and interface errors, improving field reliability and speeding up installation. This combination supports compliant protection schemes across panels, switchgear, and distribution boards, especially in high-density electrical rooms. The KTS-R-275’s compact, standardized form factor—11.63 in long, 2 in high, 2 in wide, and 2.4 lb—facilitates straightforward replacement in busy facilities and supports consistent lifecycle management. Its standard packaging and non-indicating fuse design simplify stocking, tracking, and refurbishment programs, while compatibility with Eaton Bussmann catalogs and data sheets aids procurement and engineering workflows. Finally, CE marking confirms safety compliance, and the RK1 class designation aligns with established regulatory practices, helping teams meet uptime targets and regulatory requirements with documented protection strategies.
