Eaton MPSC164WEAXX2A Magnum LV Circuit Breaker - 100 kAIC

Four-pole, standard-frame design with drawout vertical mounting enables safe, quick maintenance and precise fault isolation in crowded switchgear cabinets. This physical configuration reduces panel crowding issues and supports fast breaker replacement during routine testing or fault clearing. Ideal for new installations or panel retrofits in manufacturing lines, data centers, and process facilities, it minimizes downtime during maintenance windows. 1600 A rated uninterrupted current (Iu) and a 100 kAIC interrupt rating give the unit capability to withstand substantial fault currents without compromising selection or safety. This translates to fewer nuisance trips and shorter outage durations on feeders feeding large motors or heavy loads in industrial settings. Equipped with the Power Xpert Release PXR20 LSI trip unit, the breaker delivers advanced protection coordination and arc-energy management. The LSI logic improves selectivity across downstream devices and supports zone selective interlocking strategies, reducing collateral damage during faults and accelerating fault clearance. Compatibility with the Magnum PXR family ensures straightforward upgrades and access to renewal parts and accessories for lifecycle management. The 14.6 in depth, 16.8 in height, and 21.2 in width footprint plus a 160 lb weight help design engineers plan enclosure space and mounting clearances. The standard four-pole frame suits both new builds and retrofit projects, while the drawout mechanism simplifies testing and maintenance. Compliance with UL, CE, NEMA, and additional certifications reduces regulatory risk and eases global procurement, supporting safer operations across facilities.
