Eaton KLU-2500 Fuse - Class L, 200 kAIC @ 600 Vac
Part Number: KLU-2500
Quick Summary
Eaton KLU-2500 fuse delivers fast-acting, current-limiting protection for large motor feeders and power distribution panels. Engineers often contend with nuisance trips and slow fault isolation that drive downtime; this fuse minimizes that risk with rapid interruption and reliable performance. It carries CE marking and RoHS compliance, and its Class L design enables selective coordination in high-current systems, reducing equipment stress and unplanned outages. Designed for 600 V and 2500 A, with an interrupt rating of 200 kAIC, bolted blade ends, and a compact 5 in length, it aligns with Bussmann standards for easy installation and lifecycle protection. This combination supports safe, compliant protection across industrial applications while helping lower total cost of ownership.

FAQs
The KLU-2500 uses bolted blade end connections, requiring secure mounting in a compatible fuse block or switchgear. Verify Service Voltage is 600 V, ensure the panel supports Class L fuses, and tighten connections to the manufacturer’s torque recommendations. Use proper PPE and follow lockout/tagout procedures before servicing.
Yes. The KLU-2500 features bolted blade end connections and a 5 in body designed to integrate with typical Bussmann series protection schemes. It is suited for high-current motor feeders and power distribution panels, enabling straightforward substitution in compatible Class L fuse blocks without extensive rewiring.
A 200 kAIC interrupt rating means the fuse can safely interrupt high fault currents without catastrophic failure, protecting downstream equipment and reducing arc energy exposure. This is crucial for large motors and high‑current feeders, where fault currents can exceed standard protective devices and downtime costs rise quickly.
Yes. The KLU-2500 is CE marked and RoHS compliant, ensuring conformity with European regulatory standards and restricted substance requirements. This makes it suitable for global installations, lowering compliance risk and supporting international procurement strategies.
Since the KLU-2500 is non-indicating, plan for periodic status checks or integrate it with remote condition monitoring to track fuse health. Pairing with a sensor-enabled panel, log analytics can alert maintenance teams to fault events, enabling proactive replacements and minimizing unplanned downtime.
