Eaton KLU-1200 Fuse - Class L, 200 kAIC at 600 V
Part Number: KLU-1200
Quick Summary
The Eaton KLU-1200 fuse provides fast-acting overcurrent protection for industrial power circuits. Designers often struggle to balance rapid fault isolation with system selectivity, risking nuisance trips in complex electrical networks. This Class L fuse is RoHS compliant and CE marked, with a 200 kAIC interrupt rating at 600 V, supporting worldwide deployment. With bolt-on mounting and bolted blade-end connections, it enables fast, secure installations and reliable protection. In addition to safeguarding critical equipment, it helps reduce downtime while meeting regulatory and safety requirements for motor feeders and power distribution panels.

Bussmann series KLU Class L fuse data sheet No. 1013
Feature Fast-acting Class L current-limiting design delivers rapid fault isolation, capping fault energy and protecting downstream equipment. The business impact is reduced arc damage, extended component life, and smoother coordination with upstream protective devices. Typical applications include motor feeders, power distribution panels, and large-capacity loads in industrial facilities, where fast clearing is essential for uptime. Feature 200 kAIC interrupt rating at 600 V provides robust fault clearance for high-current events. The impact is less equipment damage and improved safety margins in DC and AC circuits, enabling tighter protection coordination. Applications include large drives and feeders that require high fault current withstand while limiting downstream disruption. Feature Bolted blade-end connections with bolt mounting simplify installation and ensure secure, vibration-resistant terminations. The business impact is reduced labor time and fewer mis-wiring incidents during replacements. It fits standard Bussmann KLU devices and is compatible with bolted blade end assemblies typical in panel boards. Feature RoHS compliance and CE marking support global deployment and regulatory alignment. The impact: fewer compliance bottlenecks in multinational projects and easier supplier qualification. The fuse is designed as Class L, current-limiting, and matches datasheet No. 1013 for reference. Feature Comprehensive documentation and compatibility resources, including catalogs and the Bussmann data sheet and UPC, support efficient specification and procurement. It ships as a standard-pack item with dimensions 10.75 in length, 2.5 in width, 2.5 in height and weight of 4.25 lb, delivering predictable lead times and easy stock management.

FAQs
Install using the bolt mounting method and ensure the blade-end terminations align with the corresponding bus bars in the panel. Tighten to the manufacturer’s torque specification, verify clean contact surfaces, and secure the fuse to prevent loosening due to vibration. The bolted blade-end design supports robust, high-current connections and simplifies replacement without rewiring.
The KLU-1200 is rated for 1200 A with a 600 V voltage rating and provides a 200 kAIC interrupt rating. It is a fast-acting, current-limiting Class L fuse with a response time of 5 seconds at 500% overload, offering rapid fault clearance and protection for sensitive downstream equipment.
Yes. Designed for motor feeders and power distribution panels, the KLU-1200 combines fast-acting protection with high fault-current withstand. Its current-limiting behavior helps prevent downstream damage and supports selective coordination with upstream protection devices, improving uptime in motor-driven applications.
The KLU-1200 is RoHS Compliant and CE Marked, facilitating global deployment and regulatory compliance across manufacturing sites. For detailed documentation and standards mapping, refer to the Bussmann catalogs and the RoHS search tools provided by Eaton.
