Four-pole Magnum frame with drawout vertical mounting and the PXR20 LSIAM trip unit enables flexible protection. Business impact: simplifies installation and replacement in crowded panels, reduces upgrade time, and supports precise fault isolation. Application: motor control centers and distribution panels in manufacturing and process industries benefit from fast, reliable protection. The unit delivers a 100 kA interrupt rating, ensuring robust short-circuit protection for high-inertia motors and feeders. This reduces arc energy exposure, minimizes potential equipment damage, and improves overall system uptime in harsh industrial environments. Global compliance footprint including UL Listed, CE Marked, and ANSI approvals lowers certification risk for multinational projects and ensures consistent protection across sites. Drawout vertical mounting facilitates maintenance without shutting down adjacent feeders and speeds service, while remaining compatible with existing infrastructures. Power Xpert ecosystem integration and Zone Selective Interlocking support advanced protection strategies, further reducing downtime and improving safety. Finally, the durable construction, 1200 A rating, and standard frame make the Magnum PXR solution a practical, long-term investment for data centers, manufacturing lines, and process industries.

FAQs

The MPSC124WEAXX2H uses a four-pole Magnum frame with drawout vertical mounting, designed for installation in motor control centers and distribution panels. Its compatibility with PXR20 LSIAM trip units and the Power Xpert Protection Manager makes it suitable for both new builds and upgrades in manufacturing floors, data centers, and process facilities.
The PXR20 LSIAM trip unit provides advanced protection logic and precise trip coordination, enabling selective protection and reduced arc energy. This translates to safer maintenance, minimized downtime during faults, and better alignment with downstream protection devices in complex feeders and motor circuits.
Yes. The MPSC124WEAXX2H carries UL Listed, ANSI, and CE Mark certifications, along with additional approvals such as CSA, ABS, DNV GL, Lloyd's Register, and KEMA. This broad certification footprint supports international deployments with reduced vendor coordination and streamlined commissioning across sites.
With a compact footprint (14.6 in depth, 16.8 in height, 21.2 in width) and a 160 lb weight, the unit fits many space-constrained panels. The drawout design simplifies replacement without disturbing adjacent components, which is especially valuable in dense motor control centers and retrofit projects.
Expect reduced downtime from improved fault isolation and fewer nuisance trips, plus easier maintenance due to service-friendly removal and replacement. Integration with Power Xpert Protection Manager enables remote protection settings, while zone-selective interlocking and validated coordination reduce overall energy losses and maintenance overhead in high-demand facilities.
