FAQs

Plan for the 14.6 in depth, 16.8 in height, and 16.2 in width footprint with a 118 lb weight. Utilize the drawout vertical mounting for serviceability, ensuring panel clearance and alignment with 3-pole feeders. Verify compatibility with existing switchgear and ensure space for the PXR20 LSI trip unit wiring and protection manager connections.
Prioritize the 1600 A frame rating and 100 kA short-circuit withstand. These specs determine the level of protection for heavy startup currents and fault clearing capability. Confirm coordination with upstream protection devices and review time-current curves (TCCs) for the Magnum PXR system to optimize selectivity.
Yes, when paired with the PXR20 LSI trip unit and proper protection coordination strategies. Use zone selective interlocking documentation and PXR tuning guides to achieve phased protection across feeders, minimizing downtime while protecting both motors and switchgear assets.
The MPSC163WEAXX2A carries UL Listed, CE Marked, and CSA Certified marks, along with other listings such as Lloyd's Register and ABS in the broader Magnum PXR ecosystem. These certifications support international procurement, customer audits, and cross-border installations.
The drawout design plus PXR20 LSI trip unit simplifies field servicing, reduces mean time to repair, and lowers downtime costs. Centralized protection management with Power Xpert Protection Manager improves visibility, enabling faster diagnostics, easier upgrades, and a clearer path to compliance and ongoing operational efficiency.
