Eaton MPSC503WEAXXSW Magnum LV Breaker - UL Listed

The MPSC503WEAXXSW offers drawout vertical mounting with no trip unit, reducing upfront wiring complexity and enabling quick field upgrades when protection needs evolve. Business impact: faster installation, lower initial costs, and streamlined maintenance in panel assemblies for power distribution lines in manufacturing and processing plants. Application: best suited for control panels and switchgear in environments where future protection upgrades are anticipated, such as automotive, food and beverage, or chemical processing facilities. The three-pole design and robust frame support high fault currents while preserving safe disconnection sequences, improving system reliability and reducing downtime during fault events. This unit’s compatibility with Magnum PXR trip units and the Power Xpert Protection Manager ecosystem enables coordinated protection, diagnostics, and easier asset management. Long-tail keywords addressed include low voltage circuit breaker for industrial panels, three-pole LV breaker, and drawout vertical mounting requirements for panel builders. Additional advantages include UL Listed and ANSI/CE compliant design, which accelerates procurement approvals and cross-border installations, while supporting regulatory compliance and risk mitigation across global sites. The device’s 5000 A frame capability and 100 kA short-circuit rating provide robust protection for feeders feeding critical loads, helping facilities avoid costly equipment damage and unplanned downtime. The product’s dimensions and weight—16.3 in depth, 16.8 in height, 31.1 in width, and 237 lb—facilitate precise space planning in new or retrofit projects and support rigid installation tolerances in dense switchgear environments. Industry insights show that modular, upgrade-friendly breakers reduce total cost of ownership by enabling staged protection enhancements without large equipment replacements.
