Quick Summary

The Eaton Magnum low voltage power circuit breaker protects motor feeders and distribution panels in industrial environments. Engineers often struggle with miscoordination, nuisance downtime, and costly maintenance when upgrading aging protection devices. It carries UL Listed, CE Marked, and multiple third‑party certifications (Lloyd’s Register, CSA) to support global compliance. Integrated with Power Xpert Release trip units and compatibility with Power Xpert Protection Manager, you gain faster diagnostics, easier settings, and lower total cost of ownership. With a standard frame and drawout vertical mounting, retrofit projects are streamlined, and service interventions are minimized in crowded panels. This combination of rating, protection features, and global certifications aligns with industrial procurement goals for reliability, safety, and lifecycle value.

FAQs

The MPSC323WEAXX2C uses a standard Magnum frame with drawout vertical mounting, enabling straightforward retrofits into many legacy switchgear configurations. Its footprint and mounting pattern are designed for quick alignment with existing buses, minimizing panel modification and commissioning time while preserving protective performance.
This breaker is rated for up to 3200 A with a 100 kA interrupt rating, three-pole configuration. The PXR20 LSIG trip unit provides adjustable protection settings, selective coordination, and diagnostic data to support precise control and maintenance planning in demanding industrial applications.
Yes. The three-pole, high interrupt rating and LSIG trip unit support motor feeders and heavy-load protection. It’s well-suited for manufacturing lines, pumps, and conveyors where reliable protection and rapid fault clearing reduce equipment wear and unplanned downtime.
UL Listed and CE Marked are primary compliance indicators, with additional certifications such as Lloyd’s Register, CSA, KEMA, ANSI, ABS, and DNV GL validating global acceptance. These credentials help streamline supplier qualification and regulatory approvals for international projects.
Power Xpert Release trip units and compatibility with Power Xpert Protection Manager enable remote diagnostics, faster settings, and proactive maintenance planning. This reduces on-site service visits, shortens downtime during faults, and lowers lifecycle costs through better protection management and data-driven decisions.
