Eaton MPSC404WEAXX2H Magnum low voltage breaker - UL Listed

Power Xpert Release PXR20 LSIAM trip unit provides staged protection and improved fault detection. Business impact includes tighter coordination and reduced nuisance trips, leading to faster restoration and safer maintenance windows. In practice, manufacturers deploy this in panelboards and switchgear where sensitive loads require precise protection and easy commissioning, such as assembly lines or data-center feeders. Drawout vertical mounting simplifies replacement and testing during maintenance. The business impact is shorter downtime and safer hot-swaps, lowering total cost of ownership. Authorized service teams can swap modules without disturbing neighboring equipment, speeding upgrades in retrofit projects and new installations. Four-pole configuration with 4000 A frame and 100 kA interrupting capacity supports large feeders and high fault currents. This reduces the need for staged protection upgrades and offers margin for future load growth. Applications include heavy manufacturing, process plants, and data centers where reliability matters most. Certifications such as UL Listed, ANSI/IEC alignment, NEMA compliance, SABA listing, CE marking, and CCC mark simplify global procurement and regulatory approvals. This breadth minimizes auditing steps and accelerates project sign-off, even for multi-site deployments. Eaton provides comprehensive technical literature for this model, including Specification Sheets, application papers, and user manuals. Access to TCC curves, renewal parts guides, and Power Xpert Protection Manager tools reduces design time and ensures correct protection settings. Compatibility with Magnum PxR ecosystem supports scalable protection strategies. Engineers benefit from consistent mounting standards across the Magnum family, aiding spare-part availability and stock planning. This design enables seamless integration with existing switchgear and minimizes field wiring errors.
