Eaton KLU-1000 fuse - Class L, 600V, 200 kAIC
Part Number: KLU-1000
Quick Summary
The Eaton KLU-1000 fuse provides fast-acting overcurrent protection for large industrial power circuits. In demanding environments, nuisance trips and downtime can cripple production when protection devices don’t match load profiles. This Class L, current-limiting fuse is RoHS compliant and CE marked, delivering robust performance under fault conditions with an interrupt rating of 200 kAIC at 600 Vac. The combination of current limiting with a high amperage rating helps minimize damage to downstream equipment while keeping energy costs in check. Designed for bolt-on installation in standard Bussmann series assemblies, it simplifies replacement and field upgrading, supporting regulatory compliance and reliability across critical power distribution paths.

Bussmann series KLU Class L fuse data sheet No. 1013
High amperage, Class L current-limiting design enables fast fault interruption while limiting downstream fault energy, reducing motor and transformer damage and maintenance costs in large power feeders. This translates to shorter downtime and improved system availability in manufacturing lines and process plants. The 200 kAIC interrupt rating at 600 Vac ensures robust protection against high fault currents typical of motor control centers, switchgear feeders, and distribution panels, helping OEMs meet safety and reliability targets. With bolted blade end connections and bolt-on mounting, installation is straightforward in existing Bussmann series configurations, enabling faster field upgrades and retrofit projects with minimal panel modification. RoHS compliance and CE marking support regulatory conformity for regional and international projects, reducing procurement friction and facilitating global sourcing. The 10.75 in length and 2.5 in width/height keep form factor predictable for enclosure planning, while a weight around 4.34 lb supports stable mechanical mounting without overloading chassis. In indicating variants, status feedback can further support preventive maintenance programs and asset health monitoring. Overall, KLU-1000 offers a durable, scalable protection solution for critical power paths.

FAQs
KLU-1000 is designed for bolt-on installation in standard Bussmann series assemblies with bolted blade ends, suitable for large power feeders and motor control centers. Its 10.75 inch length and 2.5 inch width/height let it fit typical industrial enclosures, while the 600 V rating supports a wide range of industrial applications. When planning a retrofit, confirm space in the enclosure and the mounting hardware required for a secure, code-compliant installation.
The KLU-1000 fuse is a Class L, fast-acting, current-limiting device rated at 1000 A with an interrupt rating of 200 kAIC at 600 Vac. It features a 600 V voltage rating, a response time of 5 seconds at 500% overload, and a bolted blade end connection. These specs enable reliable protection for heavy-duty power distribution panels and motor feeders while controlling fault energy.
Yes. With a 200 kAIC interrupt rating at 600 Vac, the KLU-1000 is designed to safely interrupt high fault currents common in motor feeders and power distribution circuits. Its current-limiting Class L design minimizes damage to downstream equipment, reducing repair costs and downtime after a fault event. Proper panel design and correct fuse sizing remain essential for optimal protection.
Yes. The KLU-1000 is RoHS compliant and CE marked, ensuring compliance with hazardous substance restrictions and European safety/health standards. This makes it suitable for global projects and OEM assemblies where regulatory conformity is mandatory, helping streamline procurement and installation across multinational facilities.
For best results, mount the KLU-1000 with bolt-on hardware in a compatible enclosure that supports Bussmann series fuse configurations. Ensure proper thermal clearance and unobstructed airflow to prevent overheating, and verify correct amperage rating against the load profile and short-circuit current contributions. Regular inspection of blade-end connections and a proper replacement protocol will help maintain protection integrity and minimize downtime.
