FAQs

Yes. The MPSC4A4MEAXX2Q is designed for vertical drawout mounting with motorized racking and is paired with the PXR25 LS I AM trip unit in Magnum PXr configurations. It supports seamless integration with Magnum PXR protection modules and Power Xpert Protection Manager for monitoring and commissioning.
Key ratings include a 4000 A frame, 100 kA short-circuit rating, and four poles. The PXR25 LS I AM trip unit provides advanced protection and selective coordination, reducing nuisance trips and enabling precise fault isolation in high-demand motor feeders.
Industries with large motors and critical feeders—such as data centers, metals, chemical processing, and heavy manufacturing—benefit from the high fault withstand, robust protection, and ease of maintenance provided by this Magnum charger. It is ideal for switchgear and motor control centers requiring reliable uptime.
The breaker is UL Listed and CE Marked, with NEMA compliance and additional certifications including CSA and other recognized standards. This breadth of certification supports global deployments and helps simplify regulatory compliance across sites.
Motorized racking and a drawout design reduce maintenance time and risk during inspections, while the PXR protection suite improves fault diagnosis and coordination. Combined with Power Xpert tools, this yields shorter downtimes, extended asset life, and a favorable return on investment through improved reliability.
