Quick Summary

Eaton Magnum PXR low voltage power circuit breaker provides reliable overcurrent protection for industrial power distribution and motor circuits. When coordination and downtime are critical, mismatched trip curves and hard-to-service breakers can spike maintenance costs. This unit uses an integrated PXR25 LSI ARMS trip system and zone-selective interlocking to improve selective coordination. It carries multiple certifications including CE Marked, UL Listed, and CSA Certified, supporting global deployment. For procurement and maintenance teams, the Magnum PXR offers durable construction, straightforward drawout mounting, and compatibility with Power Xpert Protection Manager workflows. In practice, engineers see improved uptime, faster fault isolation, and better regulatory compliance when integrating this model in panels and motor control centers. By leveraging the four-pole standard frame and drawout design, installation teams reduce commissioning time and simplify spare-part management.
