FAQs

The MPSC404VEAXX2A uses fixed vertical mounting on a Magnum frame and is designed for four-pole protection in large enclosures. Its dimensions (16.3 in depth, 16.8 in height, 44.1 in width) and weight (approximately 319 lb) should be matched to compatible switchgear or motor control centers. Retrofitting is streamlined when panels support standard Magnum frames and PXR trip units, reducing field modifications and commissioning time.
This breaker features a 4000 A frame with a 100 kA short-circuit rating and an integrated Power Xpert Release (PXR) LSI trip unit. Four-pole construction supports enhanced protection for three-phase systems, while the PXR unit enables precise coordination and fast tripping, improving protection selectivity and reducing arc exposure in demanding environments.
Yes. With the PXR20 LSI trip unit and the capacity for zone selective interlocking, the MPSC404VEAXX2A supports selective coordination across motor feeders and distribution panels. This minimizes unnecessary trips on nonfaulted circuits, protects critical loads, and helps meet uptime targets in manufacturing and process facilities.
The unit carries UL Listed status and KEMA certification, and is CE Marked per compliance requirements. Additional certifications include ANSI, CSA, DNV GL, and ABS, enabling global deployment across industries with robust regulatory assurance and traceable safety performance.
By enabling fast fault isolation, selective coordination, and integration with Eaton's Protection Manager, this breaker lowers downtime and maintenance overhead. The long-term value includes reduced spare parts consumption, easier updates through shared trip unit platforms, and improved asset reliability in critical power distribution networks.
