Feature → Business Impact → Application: Four-pole, fixed horizontal Magnum frame enables robust vertical stacking and compatibility with standard bus systems, reducing installation time and improving panel density in medium-voltage-to-low-voltage transitions. This translates to faster commissioning and lower total installed cost for control panels in automotive plants and packaging lines. Feature → PXR20 LSI trip unit provides selective coordination and precise tripping behavior, improving fault isolation and minimizing collateral damage to healthy circuits in data centers and process lines. Application → With 5000 A Iu and 100 kAIC interrupt rating, the breaker protects high-current feeders from damaging faults, supporting uptime in critical power pathways for industrial automation and mission-critical facilities. Feature → Double standard frame and four-pole design deliver mechanical robustness and reliable neutral handling, reducing maintenance cycles and downtime in harsh environments. Application → Suitable for panel builders and machine builders requiring durable protection in conveyors, robotics cells, and packaging lines. Feature → Broad compliance (UL Listed, CE Marked, CSA Certified, NEMA/SABA/CCC) ensures you meet global regulations without redesigning protection schemes, simplifying cross-border deployments and OEM compliance. Application → Ideal for international food processing plants and water treatment facilities where regulatory alignment and consistent protection are mandated. Feature → Power Xpert integration readiness with protection manager tools and documentation supports proactive monitoring and faster issue resolution, lowering mean time to repair (MTTR) and improving overall OEE in manufacturing operations.

FAQs
Yes. The unit features a fixed horizontal mounting style and a four-pole, double standard frame designed for compatibility with typical Magnum PXR protection assemblies and common panel layouts. This supports straightforward retrofits and upgrades within existing Eaton protection ecosystems, minimizing field wiring changes and reducing commissioning time.
Key specifications include rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 100 kAIC, four poles, and PXR20 LSI trip unit. Ensure compatibility with your busbar arrangement, panel frame, and ambient conditions. Confirm the device aligns with your coordination study results and your site’s short-circuit current levels.
Applications include data centers, manufacturing lines, and general industrial power distribution where high fault-current levels and precise protection are critical. The four-pole, double standard frame supports large feeder protections, while the PXR20 LSI trip unit facilitates selective coordination to minimize service interruptions.
The MPSC5A4HEAXX2A carries UL Listed, CE Marked, and CSA Certified credentials, along with NEMA compliance and SABA listing as noted in the datasheet. These certifications support worldwide deployments, simplify cross-border panel builds, and help satisfy electrical safety and performance requirements in many regions.
The combination of a PXR20 LSI trip unit and a robust four-pole design reduces nuisance trips and accelerates fault isolation, improving overall system reliability and uptime. Long-term ROI benefits include lower MTTR, reduced unplanned downtime, and easier compliance audits thanks to documented certifications and integration with protection management tools.
