Industrial KTU-600 Fuses

KTU-600 is Eaton’s Bussmann Series Limitron fast-acting, current-limiting fuse designed for 600 VAC circuits. It is rated at 600 A with a 200 kA interrupting rating at 600 V, delivering rapid fault isolation to protect feeders, motors, and power-distribution panels. This is a single-element, cartridge-style fuse with a melamine glass tube and a 2.5 in diameter by 8.63 in length body, equipped with bolted blade end terminals for secure mounting and bolted-on installation. As part of the UL Class L family, the KTU-600 combines fast response with predictable protection in demanding industrial and commercial applications that require precise current limiting. Construction highlights include a cartridge body and a single element design that aids in consistent performance under fault conditions. Widely cataloged as KTU-600, it is listed by major distributors as 600 VAC, 600 A, fast-acting Limitron, with an interrupting rating of 200 kAIC at 600 VAC, making it suitable for high-energy feeders, switchgear, and heavy-load protection where fast isolation is critical. Common use cases include protecting power feeds in industrial equipment, panels, and motor-drive circuits where a 600 A, 600 V fast-acting fuse is appropriate.
