Eaton KTU-1400 Class L Fuse - 200 kAIC
Part Number: KTU-1400
Quick Summary
The Eaton KTU-1400 Class L fuse is a fast-acting, current-limiting protection device for large power circuits in industrial environments. It protects feeders and motors from damaging short circuits while helping maintain electrical integrity across switchgear and panels. When outage-related energy is limited at the source, downstream components experience less stress, improving uptime and equipment life. This fuse is RoHS compliant and CE marked, supporting global procurement and regulatory adherence. The device’s bolted blade end construction and knife blade features simplify field installation and ensure robust connections in demanding environments. With a 1400 A rating and 200 kAIC interrupt capacity at 600 Vac, it delivers reliable protection in high‑power applications, aligning safety and performance with business objectives.

Bussmann series KTU Class L fuse data sheet No. 1010
High-current protection with current-limiting action reduces fault energy and protects downstream equipment, minimizing damage during short circuits and reducing downtime. This translates to safer motor feeders, power distribution panels, and switchgear in industrial plants, while enabling tighter coordination with upstream protection devices. The Class L design balances selectivity and fast clearance times, helping facilities meet NEC/IEC standards without compromising reliability in high inrush scenarios. Knife blade design and bolted blade end connections offer secure, low-resistance interfaces that resist vibration and arcing, streamlining maintenance and improving service life in harsh environments. RoHS compliance and CE marking simplify cross-border sourcing and regulatory qualification, supporting global rollouts and compliant procurement. Dimensions and material choices—melamine glass tube, silver-plated end bells, and a standard packaging format—ensure durability and predictable installation in standard fuse blocks.

FAQs
The KTU-1400 is designed for bolted blade end connections with a 600 V rating and a 1400 A amperage rating, and a 200 kAIC interrupt capacity. Verify your fuse holder and bus dimensions to accommodate the 10.75 in length and 3 in width/height, ensure blade-end compatibility, and consult the data sheet No. 1010 for installation guidance.
KTU-1400 is a fast-acting, current-limiting Class L fuse, which constrains let-through energy during a fault, reducing thermal and arc stress on conductors and switchgear. This improves equipment life, lowers maintenance costs, and enhances protection coordination with upstream devices in motor feeders and power distribution panels.
The KTU-1400 is RoHS compliant and CE marked, aligning with global environmental and safety requirements. This simplifies cross-border procurement, reduces regulatory risk in multinational plants, and supports compliance-driven sourcing for international projects and panel builds.
Industries relying on large motor feeders, switchgear, and high-current power distribution—such as metals processing, process automation, oil and gas, and heavy manufacturing—benefit from the KTU-1400. Its 1400 A rating, 200 kAIC interrupt capacity, and secure bolted blade end connections support reliable protection in demanding, 600 V environments.
