FAQs

The MPSC164MEAXXSW uses a drawout vertical design with motorized racking. Ensure the cabinet supports a standard frame, verify mounting rails, and connect the drawout path per Eaton's installation guides. For optimal operation, pair with the appropriate Power Xpert Release trip units if overcurrent protection coordination is required. Follow manufacturer torque specs for mounting hardware and verify clearances before energization.
Key ratings include four-pole configuration rated for 1600 A continuous current and a 100 kA interrupt capacity. The device is built for high-current feeders and large motor starts, providing robust fault isolation. Ensure your system fault levels are within these ratings and coordinate with upstream protection to maximize system reliability.
Yes. The MPSC164MEAXXSW is designed for heavy feeders and high fault currents typical of MCCs. Its drawout motorized racking simplifies maintenance within dense MCCs, while its high interrupt rating supports dependable protection in facilities with multiple large motors and rapid switching requirements.
This model carries UL Listed and CE Marked certifications, with additional approvals including NEMA compliance, SABA listing, and Lloyd’s Register certification. ANSI, CSA, KEMA, DNV GL, ABS certifications are also listed, providing broad regulatory acceptance for global deployments and aiding in compliance documentation.
Power Xpert Protection Manager compatibility enables centralized monitoring, event logging, and quicker fault diagnosis, reducing downtime. Although the base unit ships without a trip unit, you can add Power Xpert Release units to tailor protection coordination. Over time, this supports predictable maintenance costs, faster troubleshooting, and a clearer path to ROI in mission-critical power systems.
