Eaton MPSC163VEAXXSW Magnum low voltage power circuit breaker - UL Listed

The Magnum MPSC163VEAXXSW is a standard-frame, three-pole molded case circuit breaker with fixed vertical mounting. This configuration delivers a robust protection platform for main distribution and panelboard installations, supporting up to 1600 A and 100 kA interrupt rating in a compact footprint. The fixed vertical mount and standard frame simplify retrofits and replacements in busy industrial switchgear environments. Power Xpert Release trip-unit compatibility lets you configure protection curves and coordination without replacing the base breaker. This capability reduces nuisance trips and enables selective protection for feeders and critical motors, cutting downtime and maintenance costs. In new builds or upgrades, the ability to add or upgrade a trip unit without swapping the entire MCCB supports faster project timelines. Comprehensive certifications and compliance cover UL Listed, ANSI KEMA Certified, CSA Certified, and CE Marked, along with NEMA compliance. This mix supports global deployment and simplifies regulatory audits for facilities operating across multiple regions. The breadth of certification reduces procurement risk and accelerates project approvals. Customers can reference the supplier documentation and use the downloads library for certificates and compliance papers. Product dimensions and weight—14.6 in depth, 16.8 in height, 16.2 in width, and 118 lb—facilitate accurate enclosure space planning and mounting in crowded panels. The fixed vertical mounting supports uniform alignment with other field installed devices, improving reliability during maintenance. This predictability is especially valuable in retrofit projects or new installations in manufacturing, processing, and data-center support environments. Extensible technical documentation and renewal-part availability help extend asset life. Eaton provides manuals, datasheets, certificates, and renewal parts for Magnum PXR enabled systems, reducing downtime during service and upgrades. This ecosystem supports long-term ROI by preserving compatibility and easing parts sourcing across facility networks. From a procurement perspective, the MPSC163VEAXXSW offers a clear pathway to compliant, scalable protection with minimal risk. By pairing the base frame with optional Power Xpert Release units, teams can tailor protection to changing load profiles while maintaining standardization across sites.
