Eaton MPSC503WEAXX2C Magnum LV Breaker - UL Listed

The PXR20 LSIG trip unit delivers precise overload and short-circuit protection with selective coordination, reducing nuisance trips and arc-flash energy while improving personnel safety. This configuration supports motor feeders and process lines in manufacturing environments, where reliable protection directly translates to higher uptime and lower maintenance costs. The drawout vertical mounting and three-pole frame simplify installation, replacement, and routine maintenance in complex switchgear assemblies, shortening downtime during retrofits and new builds. With a short-circuit rating of 5000 A (ABCABC) and an interrupting capacity of 100 kA, it provides robust fault handling for high-current systems, enabling safer operation of large motors and drives and better upstream coordination. The compact footprint—16.3 in depth, 16.8 in height, and 31.1 in width—combined with a 237 lb weight supports stable, service-friendly integration in MCCs and panel boards. Compliance across UL, CSA, CE, and NEMA standards ensures global applicability, while compatibility with Power Xpert Protection Manager enables remote monitoring and protection management for reduced total cost of ownership. This combination addresses common objections about retrofits, delivering a solution that scales with evolving protection schemes and factory automation needs.
