One-time fuse design minimizes downtime by eliminating repeated fuse changes, delivering fast fault clearance in a busy production line. This translates to lower maintenance costs and improved equipment availability, especially in remote facilities where service calls are expensive. Suitable for control panels and safety circuits, the KOS250 integrates with standard Edison assemblies for mechanical compatibility and easy stocking. Knife blade contact provides a robust interface and straightforward servicing, enabling quicker replacements without sacrificing reliability. Technicians benefit from reduced tool time and safer disconnections, particularly in tight panel enclosures, making the fuse well-suited for compact MCCs and wall-mounted panels. Class K5 with a 10 kAIC interrupt rating at 600 V enables selective coordination, protecting upstream equipment while safely interrupting faults. This reduces nuisance trips and collateral damage in distribution systems, applicable to motor control centers and power distribution panels in manufacturing and process industries. With dimensions of 11 in L, 2 in W, 2 in H and a weight of 2.55 lb, the KOS250 fits standard fuse holders and cabinet cutouts, simplifying installation and retrofits. The consistent Eaton Edison form factor supports modular upgrades and straightforward maintenance planning. Inventory and compatibility are enhanced by UPC 782634372509 and alignment with Eaton’s Edison full-line catalogs, simplifying procurement and reducing stocking complexity for OEMs and maintenance teams.
