Eaton KON4 Edison Fuse - Class K5, 4 A, 250 V

Ferrule design improves connection reliability and vibration resistance, enabling steadier protection in shock-prone enclosures; the result is reduced contact fatigue and fewer field service calls. This directly translates to cost savings and longer panel life in mission-critical equipment used in manufacturing lines and utility infrastructure. The 4 A amperage rating guards small circuits without nuisance tripping, optimizing device uptime and reducing unnecessary disconnections during peak load transitions in robotics and controls cabinets. With a high 10 kAIC interrupt rating at 250 V, this KON4 fuse withstands short-circuit faults in bus ducts and control panels, boosting safety margins and protecting downstream devices. The non-indicating feature minimizes visual clutter on dense panels, facilitating quick fault diagnosis and faster replacement during maintenance windows. Class K5 construction further ensures reliable performance in high-temperature environments typical of industrial environments, while CE marking and CSA certification support global compliance. Standard packaging of ten pieces streamlines stocking, procurement, and just-in-time manufacturing workflows, reducing order cycles and inventory carrying costs. Compatibility with Eaton Edison Bussmann series protection devices ensures a seamless protective strategy across control panels, motor starters, and power distribution blocks, reinforcing a cohesive safety architecture across the plant. Installation is straightforward thanks to the ferrule design and compact footprint (2 in length, 0.56 in width, 0.56 in height), enabling dense panel layouts without sacrificing accessibility for testing and replacement.
