Quick Summary

The Eaton Magnum low voltage power circuit breaker protects electrical distribution panels by interrupting fault currents in industrial facilities. Uptime and selective protection in high-demand environments can be challenging when coordinating breakers across large motor and process loads. UL Listed, CE Marked, and NEMA Compliant certifications back global deployment and safety compliance. By leveraging the PXR20 LSI trip unit and drawout vertical mounting, it enables easier installation, faster maintenance, and scalable protection within existing panels. With a 2500 A continuous rating and 100 kA interrupting capability, this breaker supports demanding feeders while maintaining coordination with upstream and downstream devices. Organizations benefit from a scalable, modular protection strategy enabled by the PXR20 trip unit and Power Xpert integration, reducing spare parts and downtime.

FAQs

The MPSC254WEAXX2A is designed for drawout vertical mounting within Magnum standard frames, aligning with common low-voltage switchgear cabinets used in industrial facilities. Verify busbar spacing, mounting rails, and the unit’s dimensions—14.6 in depth, 16.8 in height, and 21.2 in width—to ensure proper seating and safe operation. Plan for appropriate lifting equipment given the 160 lb weight.
The PXR20 LSI trip unit provides precise protection settings and advanced coordination with downstream devices, reducing unnecessary trips and enabling clearer fault isolation. This supports safer starts, smoother motor control, and easier integration with Power Xpert Protection Manager for monitoring, diagnostics, and remote configuration across multiple feeders.
Yes. With a four-pole design, 2500 A rating, and 100 kA interrupting capability, the MPSC254WEAXX2A is well-suited for high-density motor control centers. The drawout vertical mounting facilitates maintenance and replacements without large panel depressurization, while the PXR20 trip unit supports precise coordination and rapid fault clearance in complex MCC environments.
This model is UL Listed, CE Marked, and NEMA Compliant, among others. These certifications signal adherence to internationally recognized safety and performance standards, enabling global deployment, smoother regulatory approvals, and reduced risk during audits. Additional marks like CSA, Lloyd's, and KEMA further support reliability in diverse markets.
Integration with Power Xpert Protection Manager enables centralized monitoring, diagnostics, and event analytics for the Magnum PXR trip units. This can shorten maintenance windows, optimize spare-part inventory, and improve uptime. Over the asset life, the modular trip units and proactive health checks contribute to lower total cost of ownership and faster return on investment.
