Eaton MPSC404HEAXX2A Magnum LV Breaker - UL Listed

Feature a four-pole design with fixed horizontal mounting and a high interrupting capacity supports robust protection in compact footprints. This translates to a measurable business impact: safer power distribution with reduced arc flash exposure and fewer nuisance trips, enabling continuous production in automotive, packaging, and process industries. Application-wise, the unit suits industrial control panels, machine builders, and large motor loads requiring selective coordination and fast fault isolation. The PXR20 LSI trip unit provides adjustable curves for long-, short-, and instantaneous trip settings, improving coordination with downstream protection schemes and helping prevent unnecessary shutdowns. In terms of installation, the Magnum frame supports straightforward retrofits and compatibility with Magnum-PXR accessories, minimizing field engineering time and inventory needs. Industry insight notes that upgrading to PXr-enabled breakers often yields improved diagnostic data and faster maintenance planning. The unit’s documentation and certification package further simplify regulatory audits and supplier qualification processes, reducing total cost of ownership.
