Eaton KTU-2001 fuse - Class L, 200 kAIC @ 600 Vac

KTU-2001 employs a Class L fast-acting current-limiting design that minimizes fault energy and fast clears short circuits. This approach reduces conductor heating, arc exposure, and downstream damage, translating to longer equipment life and lower maintenance costs in electrical rooms and switchgear. It is particularly effective for motor feeders, control panels, and branch circuits that demand reliable protection without sacrificing performance. With an interrupt rating of up to 200 kAIC at 600 Vac, the fuse safely interrupts high fault currents and improves selectivity across complex power distribution networks. This capability helps prevent nuisance trips and cascading failures, delivering more predictable protection for critical manufacturing processes. Durable construction uses silver-plated end bells and a melamine glass tube to resist wear from vibration and environmental conditions common in industrial facilities. The robust form factor supports easy replacement in standard Bussmann-series enclosures, while maintaining consistent electrical performance. This reliability translates to lower total cost of ownership over the equipment life. Bolt mounting and standard packaging simplify installation, alignment, and field replacement, reducing commissioning time and human error. The 10.75 inch length, 5 inch height, and 5 inch width, combined with a 17 lb weight, provide predictable space planning and cooling considerations in panel layouts. RoHS compliance and CE marking ensure regulatory readiness in global projects, while official data sheets such as Bussmann series No. 1010 support accurate specification and procurement.
