Eaton MPSC163HEAXX2Q Magnum LV Circuit Breaker - UL Listed

1600 A main frame with 100 kA interrupting capacity provides robust protection for high-demand feeders. That capability reduces the number of upstream devices needed and minimizes the risk of cascading faults in MCCs and switchgear. In practice, engineers experience fewer nuisance trips during startup and rugged operating conditions, which translates into improved line uptime and more predictable maintenance windows. The PXR25 LSIAM trip unit delivers advanced release logic and precise current sensing, enabling selective coordination with downstream breakers. The business impact is shorter fault durations and safer isolation of critical loads, even in complex bus configurations. When paired with Power Xpert Protection Manager, settings can be tuned and monitored remotely, improving diagnostic speed and reducing maintenance labor. Three-pole configuration with fixed horizontal mounting simplifies installation and reduces field adjustments. The standard frame and global certifications support quick panel integration across regional projects, while the 14.6 in depth, 16.8 in height, and 16.2 in width fit common enclosures. The 118 lb weight conveys durability for demanding industrial environments. UL Listed and CE Marked approvals, together with CSA, KEMA, ANSI, ABS certifications, minimize compliance risk for multinational projects and enable smoother supplier qualification. The combination of SABA/NEMA alignment and cross-border markings helps ensure field acceptance in diverse codes, simplifies audits, and accelerates commissioning timelines. Zone selective interlocking application papers provide practical guidance for fast fault isolation, while Magnum renewal parts and PXR user manuals support long-term maintenance. When used with Power Xpert Tools, technicians can monitor trips, trend performance, and implement firmware updates remotely, delivering measurable ROI through reduced downtime and extended service life.
