FAQs
The MPSC304WEAXX2C uses a drawout vertical mounting on a standard frame, allowing easy insertion, removal, and replacement within compatible panels. Ensure sufficient clearance and rail space for the unit, verify bus connections match the four-pole configuration, and account for mounting hardware compatibility with existing Eaton Magnum equipment to minimize downtime during retrofits.
The PXR20 LSIG trip unit provides precise load-shedding logic and adjustable protection settings, enabling selective coordination with downstream devices. This reduces nuisance trips, speeds fault isolation, and minimizes arc energy exposure, which is especially valuable for large motor feeds and critical process lines requiring reliable uptime.
Rely on UL Listed and CSA Certified marks for North American safety compliance, CE Mark for European conformity, and NEMA Compliant status for plug-and-play panel integration. Additional certifications such as CCC Marked, Lloyd's Register, and other global approvals further support cross-border deployments and customer audits.
Yes. Its four-pole construction with a PXR20 LSIG trip unit is designed to support selective coordination across multiple breakers. This configuration helps isolate faults to the nearest point of protection, reducing downstream outages and enabling simpler troubleshooting in complex motor and process networks.
Power Xpert Protection Manager compatibility enables remote diagnostics, event logging, and health monitoring of the Magnum breaker. This supports proactive maintenance planning, quicker fault analysis, and longer asset life, contributing to lower total cost of ownership and higher overall equipment effectiveness.
