Eaton MPSC4A4VEAXX2A Magnum LV breaker - UL Listed

High interrupting capacity with a four-pole design and a 100 kA clearing capability enables reliable feeder protection in demanding environments. The unit's robust Magnum frame and fixed vertical mounting simplify mechanical fit and service access in compact switchgear, reducing installation risk and total cost of ownership. The PXR20 LSI trip unit adds precision protection and selective coordination, translating to fewer nuisance trips and faster fault isolation, thereby improving equipment uptime for critical processes. In practice, these protections help facilities meet safety and reliability standards while maintaining operational continuity. This breaker ships with a double standard frame and a 4,000 A frame option, providing scalable protection for larger motor feeders while maintaining compatibility with existing cabinets. Dimensional data—16.3 in length, 16.8 in height, 44.1 in width—and a weight of 319 lb support stable panel integration and predictable mounting. Global certifications including UL Listed, CSA Certified, and CE Marking reassure procurement teams and cross-border maintenance crews. Coupled with documented time-current curves and application notes, it supports compliant design, safer maintenance, and easier training for plant personnel. Integration with Power Xpert Protection Manager enables remote protection management and data-driven maintenance planning. The availability of technical papers on selective coordination and interlocking helps engineers implement zone selective interlocking and optimized protection strategies across multi-bus architectures.
