Four-pole, fixed horizontal mounting delivers robust protection in compact control cabinets. The rigid Magnum frame simplifies installation and reduces cabinet depth, enabling faster panel builds and fewer field modifications. This is especially valuable in high-density control rooms and machine enclosures. The PXR20 LSIGAM trip unit offers configurable protection curves and arc-flash mitigation. This improves safety, reduces nuisance trips, and simplifies future upgrades as protection needs evolve in manufacturing lines and process equipment. An 85 kA interrupting rating with a 4000 A frame provides strong fault current protection. In practice, this means shorter fault clearance times, less equipment damage, and lower downtime costs during high-energy events in heavy machinery and packaging lines. Global compliance is ensured with UL Listed, CE Marked, and NEMA compatibility, supporting cross-border projects and supplier qualification. The documented certifications streamline procurement, reduce risk, and facilitate customer audits in regulated industries such as food, pharma, and automotive. Compatibility with Power Xpert Protection Manager and Magnum PXR devices enables centralized protection management and scalable coordination. Teams gain standardized settings across panels, faster commissioning, and improved maintenance planning, delivering a lower total cost of ownership. Additional resources, including zone selective interlocking guidance and selective coordination papers, help engineers implement advanced protection strategies. Real-world field feedback shows improved uptime and easier retrofits when upgrading to PXRs in existing installations.
