High-current protection is built-in with a 3500 A amperage rating and 200 kAIC interrupt rating at 600 Vac. This combination minimizes fault energy and protects downstream equipment from catastrophic arc flashes, preserving circuit integrity and reducing unplanned downtime. It is well suited for motor control centers, large power distribution panels, and other high-current applications in manufacturing environments. Durability is enhanced by silver-plated end bells and a melamine glass tube, with ferrule design that improves mechanical robustness in dusty or vibration-prone environments. This translates to longer service intervals and lower maintenance costs in rugged plant conditions. Bolt mounting simplifies installation, reduces misalignment risk, and enables secure retention in harsh environments, supporting quick panel upgrades and faster commissioning. RoHS compliance and CE marking ensure regulatory alignment across global manufacturing sites, minimizing compliance risk. The fuse’s footprint—10.75 in length with 5.75 in width and height and a 24 lb weight—facilitates space planning in dense electrical rooms while standard packaging streamlines stocking. Overall, the KTU-3500 supports reliability, safety, and cost-effective protection for power distribution systems.

FAQs
The KTU-3500 is designed for bolt mounting, with a length of 10.75 inches and a width/height of 5.75 inches, and a weight of 24 pounds. Plan for secure mounting hardware and clearance to accommodate the unit’s footprint and end-bell design. Ensure panel cavities and adjacent components can accommodate the ferrule design and allow service access for periodic inspection and replacement using the standard packaging.
The fuse provides a 3500 A amperage rating and a 200 kAIC interrupt rating at 600 Vac, delivering fast fault clearing and current limiting to minimize energy let-through. This reduces damage to motors, drives, and feeders, supporting safer shutdowns and reduced arc-flash exposure in demanding industrial environments such as motor control centers.
Yes. The KTU-3500 is a Class L fast-acting, current-limiting fuse with a 3500 A rating and 600 V operation, making it well-suited for motor control centers and large switchgear where high protection with minimal fault energy is essential. Its bolt-mount design and ferrule features simplify integration into established MCC and panelboard architectures.
The KTU-3500 is RoHS compliant and CE marked, ensuring regulatory alignment for European and global installations. This enhances market acceptance, simplifies procurement for multi-site plants, and supports compliance reporting. Datasheets and catalogs from Eaton provide further confirmation of these certifications and the device’s operating parameters.
The KTU-3500’s durable construction and high interrupt rating reduce unplanned downtime by protecting critical equipment from fault energy.
