High-capacity protection and robust construction guard critical power systems. The Magnum MPSC404MEAXX2C features a double standard frame, four poles, and a 4000 A rating with 100 kA interrupting capacity, enabling reliable interruption of large fault currents in main distribution panels. This translates into fewer nuisance trips and improved system availability in data centers and heavy industries. Drawout vertical mounting with motorized racking simplifies service and maintenance. Technicians can rack, test, or replace the breaker without powering down adjacent sections, minimizing downtime and reducing risk. Power Xpert Release trip unit compatibility (PXR20 LSIG) delivers fast, coordinated protection. This enables selective coordination across feeders and minimizes downstream outages while meeting modern protection requirements. Global certifications and compliances—UL Listed, CSA Certified, CE Marked, along with KEMA, Lloyd's Register and others—support smooth approvals in multiple regions. Seamless integration with Eaton's digital protection tools and protection managers, plus comprehensive technical data sheets and application notes, aids design engineers.
