Eaton MPSC5N4MEAXX2S Magnum low voltage power circuit breaker - 100 kAIC

Feature to business impact to application: The Magnum PXR four-pole design supports 5000 A Iu and a 100 kAIC interrupt rating, enabling reliable fault clearance in demanding distribution systems and critical manufacturing lines; this translates to improved system availability and reduced downtime in data centers and large motor drives. The drawout vertical mounting with motorized racking simplifies maintenance and replacement, cutting outage durations and enabling faster service window execution during panel upgrades or routine inspections in plant environments. The PXR25 LSIGAM protection unit provides configurable protection logic, improving selective coordination and reducing nuisance trips across complex switchgear assemblies. The double standard frame and four-pole configuration deliver compatibility with existing Magnum installations and minimize retrofit costs when upgrading mid-life infrastructure. Industry-standard certifications (ANSI, CSA, UL, CE, NEMA compliance) ensure regulatory alignment across regions, facilitating global deployments and supplier audits. These features, combined with Power Xpert Protection Manager integration, enable remote monitoring, faster fault diagnosis, and improved protective coordination, delivering measurable ROI through reduced maintenance time and fewer unplanned outages.
