Eaton MPSC124WEAXXSW Power Breaker - UL Listed

The MPSC124WEAXXSW delivers a high interrupting capacity of 100 kA within a 1200 A standard-frame four-pole configuration, enabling fast fault isolation and reduced arc energy in fault events. This translates to lower downtime and minimized equipment damage in motor control centers, process lines, and distribution panels. The drawout vertical mounting simplifies installation, inspection, and maintenance, while keeping footprint and wiring organized for easier upgrades and serviceability. As a zero-trip-unit base, the unit is ready for a seamless PXR trip unit upgrade, enabling Power Xpert Protection Manager integration for coordinated protection and remote monitoring. This compatibility supports selective coordination, zone interlocking options, and straightforward commissioning in demanding facilities. The rugged frame and modular design also reduce lifecycle costs by simplifying parts replacement and retrofits in retrofit projects and new builds alike. With certifications spanning UL, ANSI, CSA, CE, and others, it meets global safety and performance expectations across markets. The combination of a robust mechanical platform, upgradeability, and ecosystem compatibility makes it ideal for critical automation environments where uptime matters. Operators gain confidence from clear protection boundaries, predictable tripping behavior, and reduced maintenance windows, while engineers appreciate the ability to tailor protection schemes to specific load profiles and fault currents. In short, this breaker supports reliable, scalable protection across industrial power distributions and advanced automation systems.
