Eaton MPSC4A4MEAXXSW Magnum LV Power Breaker - UL Listed

Drawout vertical mounting with motorized racking enables fast, safe breaker changes in live or de-energized systems. The motorized racking reduces manual handling and arc-flash exposure, shortening maintenance windows and increasing overall equipment availability across production lines. This design is compatible with common service entrance gear and standard switchgear cabinets, simplifying retrofit projects and minimizing installation risk. Four-pole construction on a 4000 A frame with a 100 kA interrupting rating delivers robust protection for large motors and heavy loads. This configuration supports high fault-current environments typical in heavy industries, facilitating selective coordination, arc-flash mitigation, and system stability. The rugged drawout chassis reduces mechanical wear and enables reliable operation in harsh plant environments. Baseline protection without a built-in trip unit provides a simple, cost-efficient platform that can be paired with external trip units or protection schemes when needed. This flexibility lowers upfront costs while preserving upgrade paths as protection requirements evolve. Field installation remains straightforward due to familiar mounting and wiring practices used in standard LV switchgear. Comprehensive compliance and certifications—NEMA, CCC, CE, SABA, UL, CSA, ABS, and Lloyd’s Register—support global procurement and installation. These standards facilitate cross-border sourcing, reduce regulatory risk, and simplify maintenance planning for multinational plants. The product’s certifications also assist with insurance and safety approvals, improving project timelines. Compact but capable footprint with 16.3 in depth, 16.8 in height, and 44.1 in width, weighing 319 lb, the Magnum aligns with common switchgear footprints and service enclosures. The catalog number MPSC4A4MEAXXSW streamlines ordering, stocking, and spare parts planning, while the drawout design minimizes panel downtime during maintenance or replacement. Engineers benefit from consistent documentation and compatibility with Eaton’s protection management tools for centralized monitoring and coordination.
