Eaton KTK-9 Fuse - 9 A, 100 kAIC @ 600 V, CE RoHS
Part Number: KTK-9
Quick Summary
KTK-9 fuse from Eaton provides reliable overcurrent protection for control, lighting, and metering circuits. Engineers often confront tight panel spaces and the need for high interrupt ratings to prevent costly downtime. It is RoHS compliant and CE marked, with a 100 kAIC interrupt rating at 600 V for demanding industrial environments. Designed for panel builders and OEMs, it combines a compact ferrule-end design with reliable Bussmann performance. In practice, this enables faster stocking, easier installation, and consistent protection across critical electrical loops. The 9 A current rating suits control circuits, lighting feeders, and meter boards in industrial automation, helping maintain reliability and uptime. With RoHS and CE compliance, procurement teams meet regulatory expectations while standard Bussmann-series protection aligns with global component inventories.

FAQs
The KTK-9 uses ferrule-end terminations, which are compatible with common fuse holders and terminal blocks found in industrial control panels. This design enables quick, tool-free installation and reduces wiring errors during panel assembly. For retrofit projects, ensure the existing holders match ferrule-end fuses to maintain secure connections and consistent protection.
The KTK-9 provides a 9 A current rating with a 100 kAIC interrupt rating at 600 V. This combination supports fast fault clearance in control circuits, lighting feeders, and meter circuits, while safely handling typical startup surges in industrial applications. These specs help protect downstream devices and minimize downtime due to short circuits.
Yes. The KTK-9 is designed for control circuits, lighting circuit protection, and meter circuits in industrial automation. Its compact size, high interrupt rating, and durable construction make it a practical choice for panel builders and OEMs seeking reliable protection in space-constrained panels.
The KTK-9 is RoHS compliant and CE marked, ensuring regulatory alignment for EU and global manufacturing. This simplifies cross-border procurement, supports environmental and safety standards, and reduces compliance risk in multinational production environments.
The KTK-9's non-indicating design reduces part costs and inventory complexity while maintaining robust protection. Its high interrupt rating minimizes downtime by quickly clearing faults, and the ferrule-end design speeds field replacement. Overall, this translates to lower maintenance labor costs, fewer spare part SKUs, and improved panel uptime across fleets.
