MPSC083MEAXX2F Eaton Magnum low voltage power circuit breaker - PXR20 LSIGAM trip unit

Drawout vertical mounting with motorized racking enables fast, safe maintenance and minimizes downtime, letting technicians service breakers without lengthy manual operations. The business impact is lower labor costs and quicker return-to-service on critical lines, applicable to large manufacturing feeders and data-center infrastructure. The 800 A current rating with 100 kA short-circuit interrupt capability provides robust protection against high fault currents, reducing busbar damage and downstream outages in demanding applications such as heavy machinery drives and process lines. Three-pole construction supports balanced three-phase systems, improving coordination and preventing nuisance trips across typical 480 V installations found in industrial plants. The Magnum PXR20 LSIGAM trip unit delivers advanced protection features, including selective coordination and arc-energy considerations, with seamless integration to Power Xpert Protection Manager for centralized configuration and monitoring. This compatibility streamlines upgrades and lifecycle management, lowering total cost of ownership while improving reliability. The unit’s dimensions—14.6 in depth, 16.8 in height, 16.2 in width—and a weight of 118 lb provide a practical footprint for retrofit into standard switchgear enclosures, supporting straightforward installation and service access. Finally, renewal parts and accessories compatible with both ANSI and IEC ecosystems help reduce stocking complexity and simplify retrofit programs across global facilities.
