FAQs

The unit uses a drawout vertical mounting and a four-pole, double-standard frame, designed for straightforward retrofits and new installs alike. Ensure panel clearance for the 16.3 in depth and 16.8 in height, then align plug-in connectors to engage the PXR20 LSI trip unit. Using standard Eaton bus and mounting hardware minimizes installation time and reduces commissioning risk.
Key ratings include 5000 A Iu continuous current capability and a 100 kAIC interrupt rating. It is a four-pole breaker with a Magnum PXR trip unit, suitable for high-demand feeders and essential loads requiring fast fault clearance and strong short-circuit protection in demanding industrial environments.
Yes. With the PXR20 LSI trip unit and the specified high interrupt rating, the device supports selective coordination when paired with compatible protection schemes. For critical loads and zones with strict uptime requirements, this breaker helps isolate faults quickly while preserving service on unaffected circuits.
The MPSC5N4WEAXX2A carries UL Listed and CE Marked certifications, along with CSA and Lloyd’s Register certifications. These credentials validate safety, reliability, and regulatory compliance across regions, reducing audit risk and simplifying the procurement process for multinational projects.
Although the upfront cost is higher than basic breakers, the 5000 A Iu rating, 100 kAIC interrupt capability, and PXR20 advanced protection reduce downtime, extend motor and switchgear life, and simplify maintenance with Power Xpert Protection Manager integration. The result is lower lifecycle costs and improved system availability over time.
