The Magnum PXR with a double standard frame provides robust protection and standardized footprint across panels, reducing engineering time and improving interchangeability in multi-line deployments. This high interrupt rating of 100 kAIC with a rated uninterrupted current (Iu) of 5000 A translates to enhanced fault tolerance in heavy-load feeders, minimizing downtime and avoiding costly outages in manufacturing and data-center environments. The three-pole design paired with fixed vertical mounting streamlines installation, ensuring consistent alignment and ease of field wiring for installers and maintenance teams. No trip unit is included, allowing seamless integration with Power Xpert Release (PXR) trip units where selective coordination and system-wide protection management are required. Certifications and compliance—UL Listed, CE Marked, CSA, Lloyd’s Register, and DNV GL—support global deployment and regulatory adherence. Compatibility with zone selective interlocking documentation underscores its role in advanced protection schemes while delivering predictable trip performance. In practice, engineers gain faster project execution, reduced stocking diversity, and clearer maintenance planning across international sites.

FAQs

Yes. The MPSC5N3VEAXXSW is designed for fixed vertical mounting and three-pole installations within laddered or conventional power distribution panels. Its double standard frame and Magnum PXR family ensure predictable fit, allowing straightforward retrofits or integration into new builds without extensive rework. Ensure panel clearance matches the 31.1 in width and 16.8 in height specified in the datasheet.
The breaker provides a rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 100 kAIC, suitable for high-load feeders and fault current scenarios. This combination supports robust protection in heavy-industrial applications, with reliable operation under demanding startup and fault conditions. It is also compatible with Power Xpert Release trip units for enhanced control.
Yes. Its three-pole configuration, high Iu rating, and 100 kAIC interrupt capacity make it well-suited for motor feeders and large industrial load centers. The Magnum PXR design facilitates coordination with upstream protection and selective interlocking strategies, helping minimize nuisance tripping while protecting motors and drives during faults.
This breaker is CE marked and UL Listed with additional CSA, Lloyd's Register, ANSI, ABS, DNV GL certifications, plus NEMA compliance. These certifications support global deployments and regulatory compliance across regions such as Europe, North America, and parts of Asia, simplifying procurement for multinational projects.
Power Xpert compatibility allows remote protection management, faster fault diagnosis, and coordinated trip schemes (PXR). This reduces downtime and maintenance costs by enabling precise protection settings, easier replacements, and streamlined spare-part planning. In turn, projects benefit from shorter commissioning times and improved overall equipment effectiveness (OEE).
