The MPSC203MEAXX2H Magnum LV circuit breaker brings a 2000 A frame rating and a 100 kA interrupt capacity, enabling reliable protection for large feeders and heavy motors while reducing outages and arc-flash exposure. The drawout vertical design with motorized racking simplifies installation, rack-in/rack-out operations, and maintenance, lowering labor costs and downtime. The Power Xpert Release (PXR20) LSIAM trip unit delivers precise coordination and fast, selective tripping to minimize impact on non-faulted loads in complex panel boards and switchgear. Standard frame compatibility accelerates replacement and spare-parts availability across facilities, while the compact 14.6 in depth, 16.8 in height, and 16.2 in width support efficient panel planning and retrofit projects. Compliance with UL Listed, CE Marked, and KEMA Certified standards reduces regulatory risk for global deployments. Zone Selective Interlocking (ZSI) compatibility and documented best practices enable tighter protection pilots, helping manufacturers meet safety and reliability targets. The unit’s motorized racking and drawout features boost serviceability and uptime in high-demand production environments, where fast fault isolation matters. This combination of rugged protection, installation ease, and robust certification provides a clear path to a safer, more productive electrical distribution system.
