High-current capability enables protective coverage for large feeders and motors, translating to fewer components and simplified protection schemes. The MPSC124MEAXX2C delivers rated uninterrupted current (Iu) of 1200 A and an interrupt rating of 100 kAIC, ensuring robust protection for critical power feeders in manufacturing environments. This reliability supports cost-effective protection coordination and tighter control of fault energy, directly reducing maintenance costs and downtime. The four-pole standard Magnum PXR frame supports consistent protection across three-phase systems, enabling straightforward replacement and upgrade paths within existing switchgear. Drawout vertical mounting with motorized racking simplifies maintenance, enhances safe isolation, and accelerates commissioning, especially in high-density panel assemblies. Global certifications and approvals further reduce procurement risk when deploying across multiple sites. Integration with Power Xpert Protection Manager and compatible trip units streamlines protection management and data-driven decision making for utilities and OEMs.
