Eaton MPSC303MEAXX2C Magnum PXR Power Breaker - 100 kAIC

Drawout vertical mounting with motorized racking is a standout feature. This design reduces maintenance time by enabling safe, controlled replacement and testing without full panel de-energization. It is particularly beneficial in retrofit projects or high-availability installations within switchgear and motor control centers. High interrupt rating of 100 kAIC and Iu of 3000 A provide robust fault protection. The business impact is improved safety margins and minimized arc flash exposure during faults, plus reduced risk of cascading failures across feeders. In practice, it supports critical loads in continuous operation, such as pumps, conveyors, and large motors in manufacturing or data center environments. Power Xpert Release LSIG trip units deliver precise protection coordination. This enables selective tripping and faster fault isolation, improving system availability and reducing unnecessary outages. Applications include complex motor circuits and distribution panels where coordination with other devices is essential. UL Listed, CE Marked, and CCC Marked status simplifies procurement and regulatory acceptance. Additional certifications from KEMA, Lloyd's Register, CSA, DNV GL, and ABS reinforce reliability for global projects. By meeting multiple standards, operators can standardize on a single protection solution across multinational sites. With 14.6 in depth, 16.8 in height, 16.2 in width, and a weight of 118 lb, the MPSC303MEAXX2C fits standard rack spaces and heavy-duty panels. Its standard frame and compatible trip unit options streamline integration with existing Magnum PXR assets and Power Xpert Protection Manager software. This compatibility reduces engineering effort and accelerates commissioning. Industry teams report noticeable efficiency gains when adopting Magnum PXR platforms due to improved data capture, fault reporting, and coordination with protection schemes.
