Special features
Ferrule design
7 A amperage rating provides precise protection for control circuits, reducing nuisance trips and equipment wear in automation panels. This targeted protection helps maintain uptime and extends component life, especially in machine control and panel boards where fault currents can escalate quickly. The 600 V rating ensures compatibility with common industrial power distributions, enabling safer, standards-compliant operation across a range of equipment. The 10 kAIC interrupt rating guarantees safe interruption of high fault currents, enabling selective coordination and protecting downstream devices from catastrophic faults. Ferrule design simplifies termination, delivering a robust, vibration-resistant connection that reduces field maintenance and improves long-term reliability. Class K5 non-indicating protection minimizes panel clutter and simplifies upgrades, while the standard packaging of 10 per pack supports efficient inventory management. CE marking confirms regulatory alignment across many regions, and compatibility with Edison Bussmann fuse holders helps streamline installation and service planning, reducing total cost of ownership for panel builders.

FAQs
KOS7 uses a ferrule design and standard Edison Bussmann-compatible form factor, making it compatible with typical Edison fuse blocks and standard control-panel installations. Refer to UPC 782634370079 for catalog pairing and verify panel cut-outs and mounting hardware match the 5 in length and 0.81 in width to ensure proper fit.
The KOS7 is rated for 7 A, with a 600 V voltage rating and a 10 kAIC interrupt capacity. This combination supports safe interruption of fault currents in medium-duty control circuits while maintaining favorable coordination with adjacent protection devices.
Yes, for control-panel circuits and machine enclosures requiring precise 7 A protection. The Class K5 characteristics and non-indicating design help provide predictable protection without unnecessary indicators, aiding routine motor-control protection in automation environments.
The KOS7 is CE Marked, indicating compliance with applicable European health, safety, and environmental requirements. CSA certification is not applicable for this configuration, and it aligns with Eaton’s Edison series specifications for compatible protection.
The ferrule design and standard 10-piece packaging simplify installation and stocking, reducing service time and inventory complexity. With robust interruption capability and compact form, this fuse supports longer mean time between failures (MTBF) and lowers total cost of ownership for mid-sized automation projects.
