FAQs
The MPSC324MEAXX2A is built for standard Magnum PXR frames and features a four-pole configuration with drawout vertical mounting and motorized racking. Its dimensions (14.6 in L, 16.8 in H, 21.2 in W) and 160 lb weight support straightforward integration into typical switchgear, panels, and distribution boards without extensive cabinet modifications.
Key specs include a 3200 A rating and 100 kA interrupting capacity, paired with the PXR20 LSI trip unit. This combination enables precise overload and short-circuit protection, improves coordination with downstream devices, and minimizes nuisance trips for motor-driven loads like pumps, conveyors, and fans.
Yes. The Magnum PXR platform is designed to support selective coordination in complex architectures. The MPSC324MEAXX2A, with its PXR20 electronic trip unit and high interrupting rating, helps ensure upstream devices only trip for faults beyond the protected branch, reducing downtime and maintaining process continuity.
This device carries UL Listed and CSA Certified marks, plus CE Marked and NEMA compliance. Additional approvals include ANSI, KEMA, Lloyd's Register, ABS, DNV GL, and other certifications listed in Eaton’s datasheets, supporting regulatory compliance across US, Canada, Europe, and other markets.
The breaker integrates with Power Xpert Protection Manager for ongoing protection management, diagnostics, and firmware updates. For maintenance, Eaton provides quick-start guides and renewal parts; attention to motorized racking components and trip unit calibration is recommended to sustain optimal protection performance.
