FAQs

MPSC124MEAXX2S supports a four-pole, standard-frame configuration with drawout vertical mounting and motorized racking. This enables quick insertion and removal in compatible switchgear while maintaining safe operation. For retrofits, verify panel dimensions (14.6 in length, 16.8 in height, 21.2 in width) and ensure compatible mounting hardware and Eaton accessories are available.
Key ratings include rated uninterrupted current (Iu) of 1200 A and an interrupt rating of 100 kAIC. It uses the PXR25 LSIGAM trip unit, supports four poles, and comes in the Magnum standard frame. These specs enable reliable protection for large feeders and motor circuits in demanding industrial environments.
Yes. The four-pole design with a 1200 A Iu rating and 100 kAIC interrupt capability, combined with the LSIGAM trip unit, provides selective coordination and fast fault isolation for motor loads. This makes it well-suited for motorControl Centers (MCCs) and heavy-duty drives in manufacturing and processing plants.
The MPSC124MEAXX2S carries UL Listed and CE Marked credentials, with additional ANSI, CSA, and Lloyd’s Register certifications. It also aligns with SABA Listed and NEMA compliance, supporting global procurement and adherence to international electrical standards in multi-site deployments.
The motorized racking and drawout design reduce maintenance downtime by simplifying breaker replacement. Remote diagnostics through Power Xpert Protection Manager enable proactive maintenance, improving asset reliability and potentially lowering total cost of ownership through reduced plant downtime and streamlined commissioning.
