High current capability: Rated uninterrupted current (Iu) of 1200 A supports large feeders without compromising protection. This capacity translates to fewer oversized cabinets and better heat management in power distribution for manufacturing lines and data centers. Strong fault interruption: An interrupt rating of 100 kAIC ensures rapid interruption of high-energy faults, protecting equipment and minimizing arc flash risk in demanding industrial environments. Practically, this means fewer cascading trips and greater system availability during peak fault currents. Advanced protection logic: The Power Xpert Release PXR20 LSI trip unit provides precise protection coordination with other devices, enabling selective fault isolation and faster restoration after disturbances. This supports reliable operations in critical processes like extrusion, pumping, and packaging lines. Installation efficiency: Drawout vertical mounting and a standard frame simplify retrofits and maintenance; technicians can swap trip units or pull the breaker without rewiring. This compatibility also aligns with existing panels and Power Xpert workflows, reducing commissioning time. Compliance and confidence: UL Listed, CE Marked, CSA Certified, and Lloyd's Register Certified, the MPSC124WEAXX2A fulfills multiple global standards, reducing regulatory risk and accelerating multi-site deployments. Industry-ready compatibility: Designed for four-pole three-phase systems, it integrates smoothly with modern protection schemes and the Magnum-PXR ecosystem, enabling scalable protection as wiring and loads grow.
