Eaton MPSC164MEAXX2A Magnum low-voltage breaker - UL Listed

Magnum frame with four poles, 1600 A rating, and 100 kA interrupt capacity delivers high-current protection for large feeders and systems. This power circuit breaker is designed as a drawout vertical unit with motorized racking, enabling quick maintenance while keeping personnel safe. The built-in PXR20 LSI trip unit provides precise, adjustable protection curves to support selective coordination in mixed-load environments. Business Impact: Accurate protection reduces downtime and limits downstream damage during faults. By enabling motorized racking, technicians can swap breakers without removing panel components, shortening outage windows and improving safety metrics. The four-pole configuration also ensures proper neutral handling in three-phase systems, helping to prevent nuisance trips on unbalanced loads. Application: Suitable for main feeders, motor control centers, and power distribution panels in manufacturing, data centers, and process industries. Its standard frame size accommodates common bus and switchgear configurations, while the 1600 A capacity supports growth without re-engineering. The LSI trip unit's flexibility supports both ANSI and IEC settings, supporting global projects. Compatibility and installation: Integrates with Power Xpert Protection Manager for centralized protection management and event logging. The unit's motorized racking simplifies commissioning and maintenance, reducing line stops. The cataloged dimensions and weight (14.6 in depth, 16.8 in height, 21.2 in width, 160 lb) help electricians plan space and mounting. Overcoming objections: If you need strict coordination, this breaker supports selective coordination strategies, with documented time-current curves and renewal parts availability. Certifications (UL, CE, NEMA, CSA, etc.) reassure compliance teams, while the option to source renewal parts minimizes lifecycle costs and ensures long-term uptime.
