Non-indicating
Ferrule design enables a robust, solderless termination that resists contact loosening in vibration-prone enclosures. This feature translates to fewer intermittent trips, lower maintenance labor, and extended fuse life in harsh industrial environments. In practice, technicians appreciate predictable termination performance during thermal cycling, panel flexing, and repeated door openings. Applications include compact control panels, motor starters, power distribution blocks, and other Eaton Edison Bussmann-based installations where space is tight and reliability matters. With a 45 A amperage rating, KON45 provides appropriate current-carrying capacity for typical control circuits and feeder lines while staying within design margins for many industrial loads. The 10 kAIC interrupt rating ensures fast, safe disconnection during fault events, reducing damage to downstream equipment and minimizing arc flash exposure. This combination supports high-availability lines in manufacturing cells, packaging lines, and machine control panels where uptime is critical. 250 V voltage rating aligns with common industrial control voltages, enabling straightforward siting alongside 120/240 V circuits and mixed-load applications. When paired with CE Marking and CSA Certification, the KON45 meets international safety standards, simplifying supplier qualification, audits, and cross-border procurement. Users gain confidence that the fuse meets performance and labeling requirements essential for compliance documentation. Class K5 classification guides engineers to select the appropriate fuse for fast-acting protection in compact assemblies, while non-indicating status simplifies visual inspection of panel interiors and reduces maintenance overhead. The standard packaging type and single-unit quantity streamline stocking, enabling rapid replacement during scheduled maintenance and emergency outages. These attributes translate to lower total cost of ownership through reduced downtime and faster device swaps. Designed to integrate with Eaton Edison Bussmann lines, KON45 mirrors the Bussmann catalog form factor and termination method for seamless substitution or expansion. The 3-inch length and 0.81-inch width/height provide a compact footprint ideal for densely packed cabinets and equipment racks. Ferrule terminations support quick, tool-free installation with consistent torque, minimizing the risk of over-tightening or under-tightening connectors. Engineers can rely on a familiar footprint when refurbishing legacy systems or upgrading to the Edison fuse family.

FAQs
KON45 is designed for Eaton Edison fuse applications within Bussmann-style holders. It measures 3 in long and 0.81 in square cross-section, uses ferrule terminations, and ships as a 1-unit pack. Its compatibility makes it suitable for control panels, motor starters, and compact switchgear that use standard Edison fuse holders.
KON45 has a 10 kAIC interrupt rating, meaning it can safely interrupt up to 10,000 amperes of fault current. This level supports reliable protection for typical industrial feeders and control circuits, reducing fault energy transfer and safeguarding downstream equipment.
KON45 is CE Marked and CSA Certified, which demonstrates compliance with European and North American electrical safety standards. This helps with regulatory approvals, supplier audits, and cross-border procurement, ensuring the fuse meets recognized safety and performance criteria.
Class K5 designation indicates the fuse’s intended fast-acting protection profile. This helps engineers select the appropriate fuse class for specific protection schemes, particularly in compact assemblies, while the non-indicating design reduces panel clutter during inspection.
Ensure compatible ferrule terminations and correct mounting in Edison Bussmann-style holders. The KON45’s 3 in length and 0.81 in cross-section fit compact cabinets, and its 1-unit packaging simplifies stocking. Remember to verify 250 V system compatibility and observe proper torque for ferrule connections to avoid over- or under-tightening.
