The MPS85N3MEAXX2H features a rugged Magnum double standard frame and a three-pole design built for demanding industrial power distributions, delivering reliable fault interruption and reduced maintenance frequency. This directly translates to lower total cost of ownership as downtime decreases and protection coordination improves across feeders and MCCs. The 85 kA short-circuit rating and 5000 A withstand rating provide robust protection for high-energy applications, enabling safer commissioning and less risk during startup and fault events. Its drawout vertical mounting with motorized racking simplifies replacement and service, speeding up maintenance windows and minimizing panel downtime. The PXR20 LSIAM trip unit enables precise, adaptive protection settings that align with selective coordination strategies, while enabling easier upgrades via Power Xpert Protection Manager integration. Compatibility with zone selective interlocking and certification to multiple standards supports global deployments and easier compliance reporting. The unit’s compact footprint and documented dimensions aid integration into existing panels and spaces, supporting retrofit projects and new builds alike, with predictable installation time and fewer field adjustments. In practice, this means fewer nuisance trips, faster fault isolation, and clearer diagnostic data for engineers planning preventive maintenance and lifecycle upgrades.
