Eaton KTU-3000 Fuse - Class L, 200 kAIC at 600 Vac
Part Number: KTU-3000
Quick Summary
Eaton KTU-3000 fuse provides fast-acting, current-limiting protection for high-current circuits in electrical panels. Engineers often face nuisance trips and costly downtime when protecting large motor feeders and distribution blocks. The unit carries RoHS compliance and CE marking, with a 200 kAIC interrupt rating at 600 Vac for robust short-circuit protection. Designed as a bolted blade end Class L fuse, it pairs with standard Bussmann catalogs and Eaton datasheets for straightforward selection and replacement. Used in industrial automation, power distribution, and heavy manufacturing, it delivers predictable protection with clear installation expectations and long-term reliability. Its 10.75 in length and 5 in width simplify integration into existing enclosures and provide clear maintenance cues.
