Eaton KOS200 Fuse - Class K5 600 V CE Marked 10 kAIC
Part Number: KOS200
Quick Summary
Eaton Edison KOS fuse provides reliable overcurrent protection for industrial panels and motor circuits. Operators often struggle with nuisance trips or downtime when fuses don’t meet the required interrupt ratings or fit in tight electrical enclosures. This model is CE marked and tailored for Eaton’s Edison fuse family, offering a 10 kAIC interrupt rating and a 600 V voltage rating, while CSA status is Not Applicable. Designed for the Edison KOS line, it fits standard protection schemes and occupies a compact 9 in length with a 1 in by 1 in footprint. With a 1-pack quantity and non-indicating design, it enables straightforward stocking, fast replacements, and predictable maintenance. The result is improved system reliability, reduced maintenance costs, and smoother procurement workflows.

Knife blade construction provides fast, clean fuse action with consistent current interruption, reducing arc risk and wear on contacts. This design supports reliable 200 A protection in demanding panel-fed circuits, minimizing nuisance trips and unplanned downtime. In practice, technicians install KOS200 fuses in Eaton Edison fuse blocks to protect motor starters and feeders in automation plants, delivering predictable performance in harsh industrial environments. Class K5 designation offers precise coordination with upstream protective devices, enabling selective trips and minimized system-wide outages. This is critical in high-density control cabinets and manufacturing lines where a single component miscoordination can halt production. The K5 class fuse fits neatly into standard Edison protection schemes, simplifying engineering workstreams and reducing the time-to-protect for new machines. With a 10 kAIC interrupt rating, the KOS200 safely clears high fault currents without compromising adjacent equipment. This resilience is essential for facilities with strong upstream sources or bus configurations, helping meet safety and reliability targets. In automation environments, the 600 V rating further ensures compatibility with common industrial power layouts and motor control centers. 600 V operation and standard packaging support straightforward deployment across existing installations, reducing the need for special accessories or rewiring. The 9 in length and 1x1 in footprint suit tight spaces in modern panels, while the standard packaging (1 piece per package) simplifies stocking and replenishment for maintenance teams. Non-indicating fuse indicators reduce confusion in assemblies where status is monitored by separate devices, and the CE marking confirms compliance with European safety requirements, aiding import and regulatory processes. While the model carries no warranty, it aligns with Eaton's Edison line and offers proven performance in routine line protection, replacement cycles, and spare-part strategies.

FAQs
The KOS200 is designed to fit standard Edison KOS fuse blocks with knife blade contacts. It measures 9 inches in length and a compact 1x1 inch footprint, packaged as a single piece per package. This ensures straightforward installation in common control panels and motor control centers, minimizing rework during panel upgrades.
KOS200 is a 200 A fuse with a 10 kAIC interrupt rating and a 600 V voltage rating. It uses a Class K5 designation and is a non-indicating fuse. The unit is intended for standard protection schemes in 600 V industrial distributions and fits typical Edison protection configurations.
Yes. With a 600 V rating and a 10 kAIC interrupt capacity, the KOS200 is well-suited for industrial automation panels, motor control centers, and distribution feeders that operate at or near 600 V. Its Class K5 coordination helps ensure selective trips and minimized downtime in high-current environments.
The KOS200 is CE marked, indicating compliance with European safety standards. CSA status is Not Applicable for this part. In practice, CE compliance supports import and regulatory alignment in many regions, while the lack of CSA applicability should be considered when sourcing for North American compliance programs.
Procurement benefits include standard packaging and a 1-count quantity that simplifies stocking. Maintenance impact includes reduced downtime due to predictable trip behavior, easy replacement in Edison KOS housings, and compatibility with common 600 V control panels. The non-indicating design may be complemented by other status monitoring in the panel for proactive fault detection.
