Quick Summary

The Eaton Magnum low voltage power circuit breaker protects industrial power systems by interrupting fault currents in distribution panels. A common challenge is nuisance tripping and slow fault isolation, which disrupts production and drives maintenance costs; Magnum PXR helps by delivering precise, coordinated protection. Certifications such as UL Listed, CE Marked, and NEMA Compliance support regulatory approvals and panel integration. With a 6000 A Iu rating and an 85 kAIC interrupt capacity, it scales to demanding loads while maintaining reliability. Designed for four-pole, drawout vertical mounting, it integrates with Power Xpert Protection Manager to streamline monitoring and lifecycle cost optimization.

FAQs

The unit uses a four-pole, drawout vertical-mount design within a double standard frame, matching standard low-voltage switchgear configurations. Ensure panel openings and mounting rails accommodate the 44.1 in width and 16.8 in height. The Magnum PXR trip unit can be field-configured for coordinated protection, simplifying retrofit projects and minimizing panel disruption.
Iu of 6000 A specifies the maximum uninterrupted current the breaker can carry under continuous loads, while 85 kAIC indicates the maximum fault current the device can interrupt without damage. Together, they support safe operation in high-demand circuits and provide clear guidance for selectivity and coordination during fault events.
Yes. The four-pole Magnum PXR unit is designed for high availability environments and heavy electrical loads typical of data centers and manufacturing lines. Its PXR25 LSI ARMS trip unit enhances selective coordination, reducing downtime due to mis-trips, while UL Listed and CE Marked certifications ease regulatory approvals in global facilities.
Key certifications include UL Listed, CE Marked, and NEMA Compliant, with additional approvals such as CCC, KEMA, ANSI, CSA, DNV GL, and ABS depending on region. These certifications support safe operation, cross-border panel approvals, and adherence to industry standards for electrical protection equipment.
Long-term reliability reduces downtime and maintenance frequency. The Power Xpert Protection Manager integration enables remote monitoring and diagnostics, lowering onsite service visits. Although upfront costs may be higher, the combination of improved protection coordination and centralized management translates to lower lifecycle costs and faster return on investment.
