Eaton Magnum low voltage power MPSC4A4HEAXX2S - PXR

Four-pole design with fixed horizontal mounting provides a robust foundation for main distribution and feeders. This configuration delivers consistent enclosure fit, predictable trip performance, and simplified installation in standard switchgear. The unit's 4000 A interrupting rating (NABCNABC) and 100 kA fault current withstand enable protection for high-energy systems without nuisance trips, reducing downtime and extending equipment life in data centers, manufacturing lines, and process plants. Integrated PXR25 LSIGAM electronic trip unit delivers precise overcurrent protection and enables selective coordination with downstream devices. This helps avoid unnecessary tripping of unaffected equipment, speeding fault isolation and reducing arc flash exposure for maintenance crews. In practice, engineers can tune protection settings to meet local codes and coordination requirements, while still achieving fast response in peak fault conditions. Physical footprint of 16.3 in L × 16.8 in H × 44.1 in W and a weight of 319 lb ensure predictable procurement and installation in large panel boards. The four-pole frame and fixed mounting are compatible with Magnum and Power Xpert Protection Manager ecosystems, enabling seamless integration with protection management software and remote diagnostics, which reduces on-site commissioning time and improves ongoing reliability. Compliances include CE Marked, SABA Listed, CCC Marked, and NEMA Compliant; Certifications include CSA Certified, ANSI, Lloyd's Register Certified, UL Listed, KEMA Certified, ABS Certified, DNV GL Certified. This breadth of approvals supports global procurement and reduces risk for multi-region projects. Documentation bundles include zone selective interlocking and selective coordination resources, supporting engineers through planning, installation, and maintenance. From a maintenance perspective, the Power Xpert compatibility and standardized Eaton documentation streamline service, spare parts planning, and retrofit work, delivering measurable ROI through lower maintenance costs and fewer downtime events.
