High current capability and robust interruption ratings protect large feeders and heavy motor loads in industrial facilities. The MPSC124WEAXX2C delivers 1200 A Iu and a 100 kAIC interrupt rating in a four-pole, standard-frame package, ensuring reliable protection during fault conditions. This combination supports safe, continuous operation in demanding power distribution schemes while simplifying panel design and protection coordination. The Magnum PXR LSIG trip unit embeds advanced protection logic that accelerates fault clearance and improves selectivity. With precise tripping characteristics, engineers achieve coordinated protection across stages, reducing the likelihood of widespread outages. Field adjustments remain straightforward, helping maintenance teams tune protection without interrupting production. Drawout vertical mounting offers rapid insertions and removals, which minimizes downtime during testing, upgrades, or replacement. The standard frame and four-pole configuration ensure compatibility with existing switchgear, bus, and mountings in many installations. This design also supports easier inspection and safer maintenance workflows. Global compliance is supported by UL Listed, CE Marked, and CSA Certified status, along with additional industry approvals. This broad certification suite reduces procurement risk for multi-region projects and accelerates approvals with inspectors and customers. Comprehensive documentation and renewal parts availability from Eaton further simplify lifecycle management. Integration with Power Xpert Protection Manager enables centralized monitoring, data logging, and remote protection management across the electrical network. The MPSC124WEAXX2C also supports zone selective interlocking and coordinated protection strategies, which improve safety and reduce outage scope. Lifecycle value is enhanced by easy maintenance, predictable spare-part availability, and access to renewal parts and updated diagnostics.
