FAQs

The MPSC324WEAXX2A uses a standard Magnum drawout vertical mounting designed for four-pole, high-current service. It fits standard frame dimensions and panel cavities used in Magnum projects, enabling straightforward retrofits or new installations. Ensure mounting clearance and bus alignment are observed, and verify panel compatibility with the PXR20 LSI trip unit for optimal performance.
This breaker is equipped with the Power Xpert Release (PXR20 LSI) trip unit, which supports advanced protection logic for selective coordination. In practice, it isolates faults quickly at the nearest protective device, minimizing downstream disruption, improving motor life, and reducing maintenance impact in multi-drive or multi-supply plants.
The MPSC324WEAXX2A holds UL Listed and CE Marked certifications, along with CSA Certified and Lloyd's Register Certified status. Additional certifications include KEMA, ANSI, ABS, and DNV GL, with NEMA compliance and SABA listing. This broad certification mix helps streamline procurement and regulatory approvals across regions.
Maintenance is simplified by the drawout design, enabling rapid swap-out during testing or replacement without extensive panel downtime. The PXR20 LSI trip unit provides precise protection settings, reducing nuisance trips and enabling selective coordination, which lowers energy waste and improves system availability—key ROI drivers in continuous-process and data-center environments.
Industries with heavy motor loads and critical feeders—such as chemical processing, oil and gas, metals, and large manufacturing lines—benefit most. Large plant feeders, data centers, and complex automation architectures requiring robust protection and fast fault isolation will find this breaker’s high current rating, interrupting capacity, and PxR coordination highly advantageous.
