Feature Drives Business Impact Application The four-pole, drawout vertical design with motorized racking mounting speeds installation, commissioning, and maintenance, reducing downtime and labor costs across switchgear upgrades and new builds. This improves project timelines in automotive, chemicals, and metals processing where frequent maintenance is expected. Feature The unit delivers up to 85 kA breaking capacity and a 5000 A (NABCNABC) rating, enabling robust protection for high-demand loads and large motors without nuisance trips during faults. This translates to improved equipment uptime and lower repair expenses in mining, pulp and paper, and water treatment facilities. Feature The PXR25 LSIAM trip unit provides adaptive electronic protection with precise trip curves and fast fault isolation, supporting selectivity and reduced arc energy. This aligns with compliance needs and helps plant engineers optimize coordination in crowded MCCs and panelboards. Feature The Magnum PXR platform offers proven compatibility with zone selective interlocking and Power Xpert Protection Manager, enabling scalable protection architectures, centralized monitoring, and easier firmware updates. This supports modernization initiatives in food & beverage, pharmaceuticals, and petrochemical plants. Feature With a compact yet rugged footprint (16.3 in L × 16.8 in H × 44.1 in W) and a weight of 319 lb, installation planning becomes straightforward, and service accessibility is improved for retrofit projects and new installations alike. This reduces field labor and accelerates project handover in industrial environments. Feature The comprehensive compliance footprint (UL Listed, CE Marked, NEMA Compliant, KEMA Certified, CSA, DNV GL, ABS, Lloyd’s Register) provides assurance for global procurement and cross-site deployments, minimizing supplier risk and streamlining audits in multi-country projects. This is especially valuable for OEMs and EPCs delivering turnkey substations and control rooms.
