The MPSC324VEAXX2F offers a 100 kA interrupting rating, which enables safe interruption of high-energy faults on feeders and motors, reducing damage to downstream equipment and accelerating fault clearance. This translates to lower downtime and improved panelboard reliability in manufacturing lines and data center infrastructure. With a 3200 A standard frame and a four-pole configuration, installation in large distribution cabinets is streamlined, while fixed vertical mounting simplifies retrofit projects and cabinet layouts. The PXR20 LSIGAM trip unit provides enhanced protection coordination and arc energy management, helping industries meet stringent safety and reliability targets. Certifications including UL Listed, CE Marked, and other global approvals support global procurement and risk reduction. Compatibility with Power Xpert Protection Manager enables digital monitoring, event tracking, and remote protection management for tighter IT-OT integration. Together, these features reduce maintenance complexity, improve compliance, and increase overall process availability.

FAQs

The MPSC324VEAXX2F is designed as a Magnum LV breaker with a fixed vertical mounting footprint compatible with standard four-pole frame assemblies. It supports Power Xpert Release trip units (PXU/PXR family) for advanced protection coordination. When upgrading existing installations, verify the panel cutout, mounting rails, and clearance to ensure seamless retrofits without compromising short-circuit withstand or trip performance.
Routine inspection of terminal connections, breathing paths, and mounting integrity is recommended. Verify trip unit calibration if using PXR options, check for signs of overheating or arcing, and ensure the device remains within its specified temperature and ambient conditions. Maintain documentation of UL listings and swap-out intervals aligned with factory recommendations to sustain reliability.
Ideal for large motor feeds, feeders, and critical distribution networks in manufacturing, process industries, and data-center environments. The 100 kA interrupting capability and four-pole design support demanding fault currents, while the PXR20 LSIGAM trip unit enables selective coordination to minimize collateral outages during faults, enhancing overall plant availability.
This Magnum breaker carries UL Listed status and CE Marking, along with NEMA compliance, SABA listing, and other third-party certifications. These approvals help satisfy regulatory requirements across North America and Europe, simplify supplier qualification, and reduce risk when sourcing electrical protection devices for global facilities.
Expect improved uptime due to higher fault clearance capability (100 kA) and selective coordination that confines outages to the smallest zone. The integration with Power Xpert Protection Manager enables proactive monitoring, faster maintenance response, and reduced downtime costs. Over time, this translates to lower total cost of ownership and more predictable plant performance.
