Four-pole construction with drawout vertical mounting delivers precise coordination and straightforward maintenance, reducing downtime and enabling faster replacement in crowded switchgear environments. This configuration supports reliable panel integration and clean bus alignment for high-current feeders, a critical factor in large automation installations. The unit offers a high interrupting capacity of 85 kA with a 6000 A frame rating, ensuring robust protection for demanding loads and motor-start surges, while maintaining system stability and minimizing nuisance trips across critical processes. With no trip unit, the breaker provides fixed protection suitable for standard configurations where defined protection and predictable response are required, simplifying maintenance and reducing total cost of ownership. The substantial footprint and fan‑cooling design contribute to dependable performance in hot factory spaces, while the drawout feature simplifies inspection and servicing without full de‑energization. This module is designed to fit within Magnum PXR ecosystems, enabling future upgrade paths for enhanced protection and coordination. Compliance with UL Listed, CSA Certified, CE Marked, and NEMA standards supports global deployments and reduces qualification time for cross‑regional projects.
