Eaton KOS12 Fuse - Class K5 10 kAIC CE Marked
Part Number: KOS12
Quick Summary
The Eaton KOS12 fuse provides fast-acting electrical protection for control panels and distribution racks. Engineers often wrestle with nuisance trips and mismatched ratings that drive costly downtime and maintenance. Key certifications include CE marking; CSA certification is not applicable for this device, which reinforces its suitability for many standard industrial applications. With a ferrule design and 12 A rating at 600 V, the KOS12 supports common control circuits and motor starts while keeping wiring neat and reliable. The packaging and form factor simplify stocking, and the non-indicating status helps minimize nuisance resets by design, aligning with practical maintenance workflows and reducing overall risk across critical systems.

Non-indicating
Ferrule design delivers a rugged contact interface that resists loosening in crowded panels and vibration-heavy environments, reducing contact resistance and arc initiation. This translates into longer-lasting protective performance and more predictable protection on control circuits and distributed loads. The 12 A amperage rating provides precise overcurrent protection for PLC outputs, sensors, and small motor feeds, minimizing unnecessary outages during normal startup surges. A 10 kAIC interrupt rating equips the fuse to safely clear high fault currents in typical industrial feeders, supporting safer bus and panel protection. With a 600 V rating and Class K5 construction, it integrates smoothly into standard industrial power networks, offering reliable performance across a range of equipment and environments. Non-indicating status and standard packaging of 10 per order simplify installation, stock management, and field replacements, reducing downtime and inventory complexity for maintenance teams.

FAQs
KOS12 uses a ferrule design and is compatible with standard Edison fuse holders found in common electrical protection schemes, simplifying retrofits and replacements in existing panels.
The fuse is rated for 12 A, 600 V, with a 10 kAIC interrupt rating, Class K5, and non-indicating status, making it suitable for many industrial control circuits and small motor feeders.
Yes. The 12 A rating combined with a 10 kAIC interrupt rating supports common motor control and feeder protection scenarios in standard industrial environments.
The KOS12 is CE marked; CSA certification is not applicable for this device, aligning with typical global compliance requirements for Edison KOS fuses.
Non-indicating design reduces visual indicators that can fail or mislead during inspections, while standard packaging of 10 aids inventory management and rapid replacements, contributing to lower downtime and simpler maintenance planning.
