Four-pole Magnum, standard-frame design provides robust protection for feeders and mains in large panels. This unit is rated at 3000 A and 100 kA interrupting capacity, enabling it to withstand high short-circuit events without nuisance trips, reducing downtime in critical motor feeders and distribution centers. The drawout vertical mounting supports fast, safe maintenance and straightforward retrofit into existing switchgear. The PXR20 LSIAM trip unit delivers advanced protection logic with configurable settings for selective coordination. This translates to minimized outages when a fault occurs and easier compliance with industry protection schemes. Applications include large MCCs, data centers, and process lines where precise coordination improves overall plant reliability. Drawout vertical mounting simplifies maintenance workflow by enabling hot-swapping with minimal panel impact. It also preserves busbar alignment and panel footprint, easing retrofit projects and new builds in harsh environments. These mechanical advantages reduce installation time and improve serviceability during scheduled maintenance. Certifications and compliance cover UL Listed, CE Marked, and NEMA Compliant, with additional approvals from Lloyd’s Register, CSA, KEMA, DNV GL, and ABS. Global installation and auditing become smoother, accelerating project approvals and reducing risk of non-conformance across multi-site deployments. Power Xpert Protection Manager compatibility enables centralized protection management, real-time trip data, and remote monitoring. This integration supports proactive maintenance, faster fault isolation, and better decision-making across the plant protection architecture. Physical footprint and weight information—14.6 in depth, 16.8 in height, 21.2 in width, and 160 lb—facilitates accurate panel design, rack planning, and logistics. The combination of integrated protection and standard frame simplifies procurement, stocking, and field replacement.

FAQs
Mount the four-pole, standard-frame Magnum in a suitable panel with vertical drawout compatibility. Ensure clearances around the unit for heat dissipation, secure the mounting hardware, and connect the busbars per the panel manufacturer’s guidelines. Verify the PXR20 LSIAM trip unit settings for startup protection and perform a system integrity check after installation. Follow the user manual and certification requirements for a compliant, safe installation.
The MPSC304WEAXX2H is rated for 3000 A with a 100 kA interrupting capacity, four poles, and a drawout vertical mounting arrangement. It uses a PXR20 LSIAM trip unit and is part of a standard Magnum frame. These specs support high-current protection, selective coordination in large switchgear, and reliable motor feeder protection in demanding facilities.
Yes. The Magnum MPSC304WEAXX2H is designed to integrate with Power Xpert Protection Manager, enabling centralized protection management, trip-data visibility, and remote monitoring. This supports selective coordination across multiple feeders, reducing nuisance trips and enabling faster fault isolation in complex electrical architectures.
The unit is UL Listed, CE Marked, and NEMA Compliant, with additional approvals from Lloyd’s Register, CSA, KEMA, DNV GL, and ABS. These certifications facilitate international installations, help satisfy regulatory audits, and smooth multi-site deployments by meeting widely recognized safety and performance standards.
The PXR trip units are designed for reliability and long service life with periodic verification of settings and diagnostics via compatible management tools. ROI benefits come from reduced downtime due to selective coordination, lower maintenance windows thanks to hot-swappable drawout design, and easier commissioning with documented, standards-based protection configurations.
