Eaton KTN-R-125 Fuse - RK1, 125 A, 200 kAIC at 250 Vac

Feature: Fast-acting, current-limiting design reduces fault energy and protects downstream components during faults. Impact: This minimizes arc exposure, reduces collateral damage, and shortens downtime across machine cells and assembly lines, delivering measurable reliability gains. Application: Motor drives, control panels, and power distribution networks in harsh industrial environments. Feature: 125 A rating with an interrupt rating of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc, enabling wide-ranging protection for mixed voltage systems. Impact: It ensures rapid, clean disconnection of high-energy faults in both AC and DC circuits, improving protection for motors, drives, DC buses, and power distribution networks in harsh environments. Application: Industrial machinery and automated systems with mixed power rails. Feature: Rejection-style fuse construction with Class RK1 compatibility and clear identification to reduce mis-installation. Impact: Lowers commissioning risk, speeds up panel builds, and simplifies maintenance by ensuring only compatible holders can accept the fuse. Application: Standard low-voltage panel architectures and retrofit projects. Feature: Standard packaging and a single-element design with 7.1 in length, 1.56 in width, 1.56 in height, and weight of 1.01 lb, enabling straightforward integration into common enclosures. Impact: Simplifies stocking, replacement planning, and cross-project use in OEM and maintenance workflows across multiple product families. Application: OEM assembly lines and field service across manufacturing facilities. Feature: Non-indicating fuse indicator and RoHS documentation availability. Impact: Keeps panel aesthetics clean, reduces unnecessary indicators, and supports compliance verification through Eaton's RoHS tool during design reviews and end-user audits. Application: Corporate compliance programs and installation standards.
