Eaton KLU-601 fuse - Class L, 200 kAIC, 600V rating
Part Number: KLU-601
Quick Summary
Introducing the Eaton Bussmann KLU-601 fuse, a Class L fast-acting current-limiting device designed for demanding control panels and power distribution systems. Engineers often struggle with nuisance tripping and insufficient fault-current isolation in compact enclosures; the KLU-601 is built to deliver reliable protection without sacrificing wiring clarity or accessibility. This unit supports a 601 A rating, a 600 V rating, and a 200 kAIC interrupt rating to safely handle high fault currents. CE Marked and RoHS compliant, it supports global regulatory requirements. In addition to robust protection, its bolted blade end connections and bolt mounting simplify installation, while standard packaging supports streamlined procurement and maintenance workflows.

Bussmann series KLU Class L fuse data sheet No. 1013
The 601 A amperage rating provides precise selectivity in feeders and branch circuits, reducing nuisance trips while protecting wiring. This capability translates to longer equipment life and lower energy losses, especially in high-density panel environments where miscoordination is common. In application terms, it supports industrial power distribution and motor-control centers where fast, reliable protection is essential. The 200 kAIC interrupt rating at 600 Vac gives high fault-current capability, enabling safe disconnect of short circuits without cascading damage. This reduces downstream tripping and enables selective coordination in complex networks, improving system reliability and simplifying compliance with protective-device coordination guidelines. The Class L fast-acting design ensures rapid fault isolation with current-limiting action; the 5 sec at 500% rating balances protection with arcing energy considerations for safer terminations. Bolted blade end connections and bolt mounting provide a robust, vibration-resistant installation, streamlining field service and minimizing loosened connections. Compatibility with standard Bussmann series layouts and availability of the Bussmann Full Line Catalog plus data sheet No. 1013 support efficient procurement and engineering validation. The fuse also carries CE Marked and RoHS compliant status, aligning with global sustainability and regulatory expectations.

FAQs
Install the KLU-601 using its bolted blade end connections and bolt mounting method. Ensure a secure, torque-appropriate connection to matching bus bars within a panel. The unit measures 8.63 inches long, 2.5 inches wide, and 2.5 inches high, with a weight around 3.5 pounds, making it compatible with standard Bussmann series layouts. Use the same Class L current-limiting fuse to preserve protection characteristics and follow the data sheet guidelines for safe handling.
The KLU-601 provides a 601 A amperage rating, a 600 V voltage rating, and a 200 kAIC interrupt rating at 600 Vac. It is a fast-acting Class L current-limiting fuse with a 5-second response time at 500% overcurrent. These ratings enable selective protection, rapid fault clearance, and protection of conductors and equipment in demanding industrial circuits.
Yes. The KLU-601 is CE marked and RoHS compliant, aligning with international regulatory requirements for electrical protection devices used in industrial environments. This simplifies compliance across global facilities and supports sustainable manufacturing and procurement programs.
Yes. With a 200 kAIC interrupt rating at 600 Vac, the KLU-601 is designed to safely interrupt high fault currents. Its current-limiting action helps minimize fault energy, reducing arcing and downstream damage. This makes it well-suited for motor feeders and power-distribution circuits where robust protection and selectivity are essential.
Key technical resources include the Bussmann Full Line Catalog and the Bussmann series KLU data sheet No. 1013. Additional support materials such as the RoHS search tool are available to verify compliance. These documents aid in engineering validation, procurement, and ongoing maintenance planning for panels and distribution systems.
