Eaton KTU-1200 fuse - Class L, 200 kAIC at 600 Vac
Part Number: KTU-1200
Quick Summary
KTU-1200 fuse by Eaton provides fast-acting branch-circuit protection for industrial electrical systems. Engineers often contend with nuisance trips and poor selectivity in feeders and motor circuits. It carries CE marking and RoHS compliance, aligning with global safety and environmental standards while following the Bussmann Series Class L protection guidelines. For panel builders and maintenance teams, this means reliable protection, easier bolt-in installation, and predictable lifecycle costs thanks to a robust current-limiting design and a high interruption rating. With a 1200 A rating and 200 kAIC interrupt capability at 600 Vac, it protects feeders against high fault currents while preserving uptime. Its bolted blade end connections and knife blade features simplify wiring and improve reliability. The device is compatible with standard Bussmann Series components for scalable panel design.

FAQs
The KTU-1200 uses bolted blade end x bolted blade end connections and a bolt mounting method, which simplifies field wiring and ensures secure, vibration-resistant installation in industrial panels. Ensure compatible Bussmann Series components and verify panel clearance for the 2.5 in width and 10.75 in length dimensions. Use appropriate torque on blade endpoints to maintain reliable contact over time.
Key ratings include 1200 A amperage, 600 V voltage rating, and 200 kAIC interrupt rating at 600 Vac. The device is a Class L, current-limiting fuse with a melamine glass tube and silver-plated end bells. These specs enable selective protection for feeders and motors, while limiting fault energy to protect conductors and reduce downtime.
Yes. The fast-acting Class L design offers current-limiting protection for motor feeders, reducing arc flash energy and conductor damage during faults. Its 1200 A rating supports high-current motor circuits, and the bolted blade ends simplify mounting in standard control panels, ensuring reliable protection with straightforward maintenance.
The KTU-1200 is CE marked and RoHS compliant, aligning with European safety and environmental standards. These certifications help ensure regulatory compliance in many markets and facilitate procurement within multinational projects while supporting sustainable manufacturing practices.
The current-limiting design minimizes fault energy, potentially reducing conductor sizing and arc-related damage, which lowers long-term maintenance costs. Its compatibility with the Bussmann Series simplifies sourcing and spare parts, reducing downtime during replacements. The robust construction supports longer service life in rugged industrial environments.
