Feature → Business Impact → Application: Four-pole, fixed vertical Magnum frame provides a robust protection architecture that simplifies panel layouts and reduces wiring complexity, enabling more reliable motor control center installations and easier upgrade paths for aging switchgear. This translates to measurable downtime reductions and faster commissioning in manufacturing lines that require tight coordination between feeders and motors. Feature → Business Impact → Application: PXR20 LSIAM trip unit enables precise, adjustable protection curves and zone-selective coordination, improving fault discrimination and reducing nuisance trips across complex processes. Ideal for high-availability facilities such as data centers, hospitals, or chemical processing plants where reliability is non-negotiable. Feature → Business Impact → Application: High interrupting capacity of 5000 A and an 85 kA short-circuit rating protects upstream transformers and feeders, limiting fault energy and protecting downstream equipment during faults. This is essential for large motors and heavy equipment in pulp and paper, metals, and plastics processing. Feature → Business Impact → Application: Comprehensive certifications (CE, UL, ANSI, KEMA, CSA, DNV GL, ABS) support global deployment and customer audits, simplifying procurement and compliance. This is valuable for multi-site rollouts and regulated industries. Feature → Business Impact → Application: Compatibility with Power Xpert Protection Manager and PXR concepts enables remote monitoring, firmware updates, and streamlined maintenance planning, driving lower total cost of ownership and better asset health tracking. Perfect for OEMs integrating protection with lifecycle services. Feature → Business Impact → Application: Dimensions and mounting (four-pole, fixed vertical mounting) support streamlined integration into existing panel footprints with predictable installation, reducing rework and project risk in new builds or retrofit projects.

FAQs

The MPS85A4VEAXX2H uses a four-pole Magnum frame with fixed vertical mounting, designed for straightforward installation in MCCs and large switchgear. This setup minimizes panel space conflicts and simplifies alignment with bus bars and accessories, while supporting zone-selective coordination through the PXR20 trip unit.
PXR20 provides advanced protection curves and coordination logic that isolate faults quickly without unnecessary trips. This reduces nuisance outages, improves motor start reliability, and lowers downtime in complex motor networks such as conveyors, pumps, and process lines.
Yes. The MPS85A4VEAXX2H carries CE Marking, UL Listed status, and ANSI/KEMA certification, among others. This broad approvals portfolio supports global procurement, regulatory audits, and safe operation across regions including North America, Europe, and international markets.
Consider the four-pole frame, fixed vertical mounting, and the unit’s dimensions (approximately 16.3 in length, 16.8 in height, and 44.1 in width) to ensure adequate panel depth and clearance. Plan for PXR20 wiring, accessory space for the protection module, and compatibility with protection management systems.
Expected ROI comes from reduced unplanned downtime, lower nuisance trips, and simpler maintenance via remote monitoring and diagnostics through Power Xpert Protection Manager. The PXR20 trip unit enables precise fault discrimination, extending service intervals and protecting critical equipment, which lowers total cost of ownership over the life of the protection system.
