FAQs

Yes. The MPSC123WEAXX2S supports integration with Eaton's Power Xpert Protection Manager ecosystem, enabling centralized protection monitoring, event logging, and configuration management. This improves visibility across distribution panels and helps optimize protection settings for efficiency, safety, and rapid fault diagnosis.
Key specs include a 1200 A continuous rating, 100 kA short-circuit rating, three-pole arrangement, and a Magnum PXR25 LSIGAM trip unit. It uses a standard frame with drawout vertical mounting, making it suitable for common low-voltage switchgear and panel boards in industrial facilities.
It is ideal for main feeders and critical power distribution in manufacturing lines, process automation panels, and motor control centers. Its high short-circuit rating, precise coordination with PXR trip units, and easy retrofit mounting support reliable protection and uptime in demanding environments.
The unit is UL Listed and CE Marked, with additional certifications including CSA, KEMA, ABS, DNV GL, and Lloyd's Register where applicable. These certifications help meet global regulatory requirements, streamline supplier qualification, and reduce risk when deploying in multi-region facilities.
Expect reduced downtime from improved fault isolation, lower maintenance and replacement labor due to drawout mounting, and stronger protection coordination with PXR25. When paired with Protection Manager, this delivers improved MTTR, fewer nuisance trips, and lower total cost of ownership across distributed energy systems.
