Eaton MPSC4N4MEAXX2C Magnum Low-Voltage Breaker - UL Listed

The MPSC4N4MEAXX2C uses a drawout vertical design with motorized racking mounting, which significantly improves safe access during testing and maintenance. This arrangement minimizes manual handling, speeds up breaker replacement, and reduces seating or alignment errors, translating to shorter downtime during plant changes and easier panel upgrades in industrial facilities. The PXR20 LSIG trip unit offers adjustable electronic protection, enabling precise long-, short-, and instantaneous-trip coordination so downstream devices trip only when necessary, reducing nuisance trips and protecting critical loads. Four-pole construction on a 4000 A frame with a 100 kA short-circuit rating supports large motor feeders and high fault currents, enhancing reliability and reducing upstream equipment stress while simplifying integration into existing bussing schemes. Compatibility with Power Xpert Protection Manager enables centralized monitoring, faster commissioning, and streamlined protection-management workflows across the plant. UL Listed, CE Marked, and NEMA compliant certifications, along with CSA and Lloyd’s Register approvals, simplify global deployments and supplier qualification, lowering project risk and accelerating procurement cycles. The product’s motorized racking and documented selective coordination guidance from Eaton improve safety and performance during maintenance and fault isolation in rigorous industrial environments.
