Eaton KTK-45 Fuse - 600 V RoHS
Part Number: KTK-45
Quick Summary
Eaton KTK-45 fuse provides reliable overcurrent protection for control circuits and lighting systems. In crowded control panels, engineers contend with a small footprint and non-indicating fuses that hinder fast fault diagnosis. This device carries CE marking and RoHS compliance, meeting global safety and environmental standards for industrial installations. Rated for 45 A and 600 V, it uses a melamine tube with nickel-plated bronze endcaps and ferrule-end connections to ensure rugged operation in harsh environments. Its compact design and standard ferrule terminations simplify panel integration and maintenance, delivering dependable protection without sacrificing space or serviceability.

Compact footprint → Enables high-density panel layouts, reducing cabinet size and material costs while preserving protection performance in electrical protection applications. This supports faster installation timelines and easier service in industrial automation environments, especially where space is at a premium. 45 A at 600 V rating → Provides robust protection for medium-power control circuits, lighting, and meter interfaces without overstressing components. The clear current and voltage boundaries help engineers design safer, more reliable electrical protection schemes in control cabinets and distribution panels. Ferrule end x ferrule end connections → Delivers secure, repeatable terminations that minimize wiring errors and rework. This accelerates panel assembly and simplifies maintenance in highly regulated environments such as food & beverage, water treatment, and manufacturing lines. Melamine tube with nickel-plated bronze endcaps → Delivers mechanical strength and corrosion resistance suitable for harsh industrial environments. This combination supports long service life in panel enclosures exposed to dust, humidity, and vibrational stress. Non-indicating design → Reduces component visibility requirements and procurement cost, while encouraging the use of panel instrumentation or auxiliary indicators for fault monitoring. For critical line protection, this design pairs with condition monitoring and diagnostic tooling to maintain uptime. CE Marked and RoHS Compliant → Simplifies global procurement and regulatory acceptance across regions, enabling seamless deployment in multinational facilities. The standard packaging and ferrule-to-ferrule connectivity further streamline installation and field servicing in electrical protection and circuit control.

FAQs
Yes. The KTK-45 uses ferrule-end connections (ferrule end x ferrule end), which are common in control panels. This design simplifies wiring, reduces connection errors, and supports quick field installation with standard ferrule terminals.
The KTK-45 is rated for 45 A and 600 V. These ratings suit medium-power control circuits, lighting circuits, and meter circuits within industrial automation equipment, ensuring reliable protection without nuisance opening in typical control panels.
The KTK-45 carries CE marking and RoHS compliance. CE indicates conformity with essential health, safety, and environmental requirements for many regions, while RoHS ensures restrictions on hazardous substances, supporting safer and compliant installations in global facilities.
Install the KTK-45 with ferrule-end terminations in clean, dry panels using appropriate ferrules and rated wiring. Ensure correct orientation and secure clamping to minimize vibration effects. Follow standard safety practices and leverage existing diagnostic tools for quick fault detection since the fuse is non-indicating.
Plan for routine panel inspections and pull-test checks on connections to prevent loose ferrules. Because the fuse is non-indicating, pair it with panel indicators or monitoring systems to detect blown fuses early, reducing mean time to repair and improving uptime in manufacturing lines.
