The Magnum four-pole frame with drawout vertical mounting enables straightforward installation and serviceability across large switchgear cabinets, reducing commissioning time and field modifications in data centers and industrial facilities. This leads to measurable uptime improvements and lower labor costs during maintenance windows. The 2000 A Iu rating and 100 kAIC interrupt capacity ensure protection for high-current feeders and critical equipment, translating into fewer re-energizations and minimized equipment damage during faults. The PXR25 LSIGAM electronic trip unit delivers zone selective interlocking and precise fault isolation, which improves coordination among feeders and reduces arc energy exposure for maintenance personnel. Global certifications such as UL Listed, CSA Certified, and CE Marked, along with Lloyd's Register, ABS, and DNV GL, provide regulatory confidence and simplify cross-border procurement for multinational projects. Compatibility with Power Xpert Release and protection-management tools enables seamless integration into modern digital ecosystems, supporting monitoring, reporting, and lifecycle optimization. Real-world data from field deployments shows improved protection schemes, reduced nuisance trips, and longer asset life when combined with Power Xpert Protection Manager and up-to-date renewal parts and accessories.
