Eaton MPSC503VEAXXSW Magnum low voltage - UL Listed

High interrupting capacity and a rugged Magnum frame deliver dependable protection for demanding feeders. With a 5000 A interrupting rating (ABCABC) and a 100 kA short-time withstand, this breaker keeps critical loads safe during faults, reducing arc flash exposure and improving safety margins. In industrial panel boards and switchgear, that translates to fewer nuisance trips and faster fault clearance during peak demand periods. Trip-unit readiness and compatibility options address evolving protection schemes. Although supplied without a trip unit, the base MPSC503VEAXXSW is designed for seamless addition of Power Xpert Release trip units, enabling precise selective coordination and easier upgrades without replacing hardware. This flexibility lowers total installed cost while delivering industry-standard protection performance. Fixed vertical mounting and a large 3-pole frame simplify installation in standard enclosures. With dimensions of 16.3 in depth, 16.8 in height, and 31.1 in width, plus a substantial 237 lb weight rating, technicians can handle bussing and wiring efficiently, which reduces commissioning time and minimizes field adjustments. Compliance with UL Listed, CE Marked, ANSI/CSA certified requirements, and multiple third-party certificates provide confidence for cross-border projects. This broad certification coverage supports regulatory alignment for global manufacturers and distributors, helping procurement meet internal standards and customer requirements on schedule. Integration with Power Xpert Protection Manager supports centralized protection, monitoring, and alarm management. When combined with zone selective interlocking and coordination papers, it supports safer, more reliable operation and potential energy savings by reducing unplanned downtime and improving system availability.
