Eaton KOS30 Fuse - 30 A, 10 kAIC Class K5, CE Marked

Ferrule design provides a robust terminal interface, ensuring consistent contact pressure, minimal risk of loose connections, and reliable performance even under vibration, thermal cycling, and frequent cycling events typical in industrial environments. This feature reduces contact wear and intermittent trips, lowers maintenance labor costs, and extends panel life by enabling repeatable, field-friendly replacements. The KOS30 offers a 30 A amperage rating, a 600 V voltage rating, and a 10 kAIC interrupt capability, delivering decisive protection for motor feeders and control circuits in demanding production lines. In practice, these specs translate to higher fault tolerance during short-circuit events, reduced collateral damage to downstream devices, and safer, more predictable shutdowns that support uptime targets. Class K5 fast-acting characteristics are chosen to optimize protection coordination within Eaton Edison assemblies, helping you avoid nuisance trips without compromising rapid response to true faults. The non-indicating design simplifies panel aesthetics and maintenance workflows, while the ferrule construction supports quick, reliable terminations with minimal torque sensitivity. Compact dimensions—five inches long and 0.81 inches wide and high—facilitate installation in crowded control panels and narrow enclosures, reducing the need for panel redesigns. Packaging is standard at ten pieces per carton, enabling efficient stocking, while CE marking confirms compliance with European safety requirements and broad market acceptance. Compatibility across the Eaton Edison fuse family means technicians can substitute KOS30 with confidence during preventive maintenance and service campaigns, reducing training time and the risk of mismatched parts. The ferrule design and standard packaging also support lean procurement processes and lower total cost of ownership. While the product specifies no warranty, buyers can rely on Eaton's specification sheets and catalogs for installation guidance, performance verification, and application notes that underpin ROI calculations and long-term reliability in production environments.
