FAQs

The MPSC123WEAXX2H is designed for drawout vertical mounting within standard Magnum frames. It fits three-pole configurations and supports quick insertion/removal for maintenance. When installed in compatible switchgear or panels, ensure proper alignment with the rail system, verify the busbar clearance, and connect the PXR20 LSIAM trip unit for full protection functionality. Use Eaton installation guides to confirm torque values and wiring schemes for reliable performance.
Key ratings include a 1200 A continuous current rating and 100 kA short-circuit rating, three-pole construction, and a Power Xpert Release PXR20 LSIAM trip unit for advanced protection logic. These features support selective coordination and fast disconnection in high-demand feeders. Compatibility with protection software enables monitoring and integration with protection management workflows, enhancing reliability in process and manufacturing environments.
Yes. The Magnum MPSC123WEAXX2H is well-suited for motor control centers and process automation panels due to its high interrupt capability, drawout mounting, and PXR20 LSIAM trip unit. Its robust certifications (UL Listed, CE Marked, NEMA CCC) and compatibility with protection management tools make it a strong choice for centralized protection, easy maintenance, and scalable automation architectures.
The breaker carries UL Listed, CE Marked, and NEMA CCC compliance, along with SABA listed and other certifications (ANSI, KEMA, ABS, DNV GL) per the data. These certifications matter because they confirm adherence to global electrical safety, performance, and interoperability standards, reducing project risk and enabling cross-border procurement and installation in regulated industries.
Recommended resources include the Magnum PXRs product aids, application papers on selective coordination, and the Power Xpert Protection Manager tools. Also consider renewal parts and accessories documentation to plan lifecycle maintenance. These assets support faster commissioning, lower maintenance costs, and longer equipment life, delivering tangible ROI for high-demand electrical distribution systems.
