FAQs
To install the KOS50, verify the panel is rated for 600 V and up to 50 A. Use the ferrule design for secure connections, ensuring proper alignment in compatible fuse holders. The fuse comes in standard packaging of 10 pieces, aiding rapid stocking and replacement during maintenance without sacrificing safety.
The KOS50 is a 50 A fuse with a 10 kAIC interrupt rating and a 600 V voltage rating. It uses a Class K5 ferrule construction and is non-indicating, designed for Edison fuse applications in industrial control gear and switchgear. Primary UPC is 782634370505 for procurement traceability.
Yes, its compact 5 in length and 1 in by 1 in footprint support dense panel layouts. The ferrule design aids reliable wiring in tight spaces, and its standard packaging helps maintenance teams keep critical spares readily available, reducing downtime during fault conditions.
The KOS50 is CE marked and CSA certified, aligning with European and North American safety requirements. This validation supports global sourcing and project approval while maintaining consistent protection performance in industrial environments.
There is no warranty stated for this fuse, so plan for regular electrical testing and scheduled replacements based on system duty. The 10-piece packaging helps minimize stockouts, and the non-indicating design means status checks rely on instrumentation rather than visual indicators.
