With a 3200 A standard frame and 100 kA interrupting rating, this Magnum breaker handles large feeders and motor loads without sacrificing protection reliability. That high rating translates into fewer nuisance trips and better selectivity with upstream devices, reducing unplanned downtime in manufacturing lines and process controls. In practice, engineers can confidently deploy the unit in power distribution panels where fault currents may spike, avoiding oversizing and unnecessary equipment upgrades. The PXR25 LSIAM electronic trip unit delivers precise, adjustable protection curves and advanced diagnostics. This enables improved protection coordination and faster fault isolation with configurable trip settings and remote monitoring readiness. It is well suited for machine control panels and critical loads where uptime matters, including packaging lines and process lines. Fixed vertical mounting and a standard frame provide straightforward integration into existing enclosures. The mounting arrangement simplifies retrofits and reduces installation time while maintaining compliant clearances and accessibility. This makes the unit ideal for panelboards, switchgear, and industrial control cabinets in new builds and retrofit projects. The combination of NEMA, UL, CE, CCC certifications, and CSA marks offers broad regulatory acceptance. This mix supports global deployment and helps verify compliance across sites and customers. It is particularly valuable for manufacturers serving international markets and regulated industries. Power Xpert Protection Manager integration enables remote monitoring, protection management, and event analysis. This capability delivers centralized fault data, predictive maintenance insights, and potential cost savings from reduced unplanned downtime. It is especially beneficial for plants pursuing uptime metrics and asset optimization. Physical footprint and weight—L 14.6 in, W 16.2 in, H 16.8 in, and 118 lb—are manageable within standard panel spaces. This facilitates easier rack layout planning and straightforward replacement in existing gear. It supports both new-build installations and panel retrofits in heavy industries.

FAQs
The MPSC323VEAXX2Q is designed for fixed vertical mounting within standard Magnum frames and compatible panelboards. It aligns with common busbar connections and the Magnum PXR family. Ensure enclosure clearance, rail alignment, and wiring practices meet the 14.6 in L x 16.2 in W x 16.8 in H footprint and the 118 lb weight specification for a trouble-free retrofit or new install.
Key ratings include a 3200 A frame with a 100 kA interrupting capacity and a three-pole configuration. The PXR25 LSIAM electronic trip unit provides adjustable protective curves, arc energy management, and diagnostic feedback. This enables precise protection coordination across feeders and motor loads, reducing nuisance trips while maintaining safety and compliance with industry standards.
Yes. The 3200 A frame and 100 kA Icu rating support high-current motor feeders and large motor start/stop transients. When paired with selective coordination strategies and the PXR25 LSIAM trip unit, it helps isolate faults quickly without impacting downstream equipment, improving uptime for conveyors, pumps, and processing motors.
This breaker carries UL Listed, CE Marked, CSA Certified, and additional approvals such as Lloyd's Register and SABA listings. These certifications validate safety, performance, and regulatory acceptance across multiple regions, simplifying global deployment, supplier qualification, and customer audits in regulated industries.
Power Xpert Protection Manager integration enables remote monitoring, event logging, and protection management for this breaker. Digital diagnostics, software updates, and compatibility with protection workflows reduce maintenance costs, enable predictive maintenance, and support asset optimization across plant networks.
