Three-pole KD plug-in design simplifies installation and maintenance, reducing commissioning time and spare-part complexity for busy industrial floors. This directly translates into faster project turnarounds and lower field labor costs, enabling rapid protection deployment in automation and packaging lines. The unit’s 300 A rating with 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC ensures robust fault-current handling, minimizing equipment damage and downtime in high-demand applications such as metal fabrication, conveyors, and large-motor drives. With 100% neutral and 50% internal grounding, neutrals are fully supported while grounding remains streamlined, improving fault isolation and reducing ground fault risk in sensitive control panels and mission-critical processes. Compliance-focused features, including NEMA, CSA, ANSI, IEEE, and UL 857 certifications, help meet regulatory requirements and customer procurement standards, supporting faster approvals and safer installations across industries. When space is at a premium, the compact K-frame, plug-in architecture, and well-defined busway compatibility simplify panel design and retrofit projects, delivering predictable footprints and easier inventory planning. The Eaton warranty—one year from installation or eighteen months from shipment—adds reassurance for procurement teams managing long-term maintenance and total cost of ownership across multi-site operations.
