FAQs

The MPSC404MEAXX2Q uses a drawout vertical mounting with motorized racking, designed for Magnum PXR-based switchgear. It fits standard low-voltage panels and motor control centers requiring a four-pole, high-availability breaker with protection coordination. Ensure mounting rails and bus connections comply with the 44.1 in width and 16.8 in height footprint, and verify alignment with the PXR25 LSIAM trip unit for correct trip curve selection.
Key ratings include four poles and a 100 kA short-circuit rating with a 4000 A frame. The PXR25 LSIAM trip unit provides advanced protection characteristics and adjustable trip curves for precise coordination. Time-current curves, maintenance diagnostics, and protection settings can be reviewed via Eaton’s documentation and the Power Xpert Protection Manager for improved reliability and reporting.
Ideal for heavy motor loads in manufacturing, process industries, and power distribution panels. It supports safe maintenance with motorized racking and zone selective interlocking documentation, making it suitable for large motor control centers, packaging lines, and metal/plastics processing plants where uptime and protection coordination are critical.
The MPSC404MEAXX2Q is UL Listed and CE Marked, with NEMA compliance and SABA listing. It also carries ANSI, CSA, Lloyd's Register, ABS, DNV GL, and KEMA certifications, ensuring global acceptance and regulatory alignment across multi-site installations.
Motorized racking reduces maintenance time and exposure to live equipment, while the PXR trip unit improves protection coordination, potentially reducing spare-part and downtime costs. Downloads and manuals, such as protection manager guides and zone selective interlocking papers, support ongoing optimization and faster troubleshooting across sites.
