Bussmann series KTU Class L fuse data sheet No. 1010
The Class L design provides selective overcurrent protection for high-current circuits, reducing unwanted interruptions while preserving critical loads in motor drives and power distribution. The fast-acting, current-limiting nature minimizes arc energy during faults, improving personnel safety and protecting sensitive electronics downstream. A 200 kAIC interrupt rating at 600 Vac ensures the fuse clears faults promptly in demanding industrial environments, helping prevent cascading failures in control panels and switchgear. With a 900 A rating and bolted blade end x bolted blade end connections, installation aligns with standard Bussmann series practices, streamlining maintenance and spare-part management. The melamine glass tube with silver-plated end bells offers durability in harsh environments, while CE and RoHS compliance support global deployment. This fuse couples robust protection with straightforward replacement during routine service windows. compatibility with standard packaging and mounting methods reduces downtime during part swaps and inventory carrying costs.

FAQs
To install the KTU-900, ensure the panel wiring aligns with bolted blade end x bolted blade end connections and that the enclosure is rated for 600 V. Mount the fuse into a compatible holder or holder-equipped panel using proper torque on the mounting hardware. Verify that the physical dimensions (10.75 in length, 2.5 in width) fit the designated compartment and that the circuit is de-energized before replacement.
The KTU-900 provides a 900 A amperage rating with a 600 V voltage rating. It has an interrupt rating of 200 kAIC at 600 Vac, classifying it as a high-current, current-limiting Class L fuse suitable for demanding industrial power circuits and motor drive protections.
Yes. The KTU-900 is CE marked and RoHS compliant, ensuring regulatory acceptance in European assemblies and alignment with restrictions on hazardous substances. This helps simplify compliance documentation and supports safer material choices in global deployments.
KTU-900 is well-suited for high-current protection in industrial control panels, motor drives, and power distribution assemblies. Its Class L, fast-acting design minimizes nuisance trips from transients while delivering reliable protection for downstream electronics and control systems in manufacturing environments.
During maintenance, replace only with identical KTU-900 specifications to preserve protection performance. The non-indicating fuse requires visual or panel-status checks to confirm operation, and standard Bussmann catalog references simplify ordering. Maintain an inventory of spare units to reduce downtime, and verify mounting hardware and bolt connections remain secure after replacement.
