FAQs

Yes. The MPSC123WEAXX2Q uses a standard Magnum frame and three-pole drawout vertical mounting, designed to fit alongside existing PXr protection units. Ensure bus connections and mounting rails match Eaton specifications, then integrate the Power Xpert Protection Manager for centralized coordination and diagnostics to maximize protection uptime.
Key specs include three poles, 1200 A current rating, 100 kA interrupting capacity, drawout vertical mounting, standard frame, and the PXR25 LSIAM trip unit. Dimensions are 14.6 in (depth) by 16.8 in (height) by 16.2 in (width), with a weight of 118 lb, enabling robust protection without excessive footprint.
Yes. Leveraging the PXR25 trip unit and precisely defined trip curves, it supports selective coordination with upstream and downstream devices. For guidance, Eaton’s selective coordination application paper IA0120000E3 and related PXR documentation help design coordination schemes that reduce nuisance trips while maintaining safety.
The breaker is UL Listed, CE Marked, and NEMA Compliant, with CSA, KEMA, Lloyd's Register, ABS, and DNV GL certifications also listed. These certifications ensure global compliance, safety, and reliability, helping procurement meet regulatory requirements and enabling cross-border project deployment.
The PXr trip unit provides accurate protection and faster fault clearing, reducing downtime and maintenance costs. Availability of renewal parts, compatibility with Protection Manager for asset health monitoring, and documented lifecycle support improve reliability and total cost of ownership across multi-site operations.
