FAQs

For seamless integration, ensure the MPS85A4HEAXX2A is mounted horizontally in a standard low-voltage cabinet, connected to the Power Xpert Protection Manager where available, and configured with the PXR20 LSI trip unit to establish proper selectivity. Verify busbar alignment, simultaneous phase connections, and confirm upstream protection settings to achieve coordinated tripping across feeders and main circuits. Always reference the latest Eaton installation guides and the PXR user manuals for sequence and safety procedures.
This breaker features a four-pole frame with a 5000 A interrupting rating and an 85 kA SCCR, designed for high-energy fault protection. The PXR20 LSI trip unit provides adjustable and precise protection curves, enabling selective coordination and reliable fault isolation. The unit is suitable for demanding industrial feeders and motor circuits, offering rapid fault clearing while minimizing collateral impact on surrounding equipment.
Yes. The Magnum design with PXR20 LSI trip, four-pole configuration, and high interrupting capacity makes it well-suited for data centers and motor feeders where uptime is critical. Its robust coordination capability helps prevent unnecessary outages, while UL and CE certifications facilitate global deployments. In data centers, reliable protection of feeders and IT infrastructure translates directly to improved service continuity.
The MPS85A4HEAXX2A carries UL Listed, CE Marked, ANSI, and Lloyd's Register certifications, among others, with additional approvals such as CSA, ABS, and DNV GL. Compliance with NEMA standards and CCC Marked status further supports international projects. These certifications reduce procurement risk and simplify cross-border installations in regulated environments.
Maintenance benefits stem from the PXR20 LSI trip unit’s reliability and the breaker’s robust build, which reduces nuisance trips and shortens fault-clearing times. The fixed horizontal mounting simplifies service access, while standardized spare parts and compatible protection software streamline updates. Over time, these factors contribute to lower downtime costs, reduced maintenance labor, and a favorable ROI for facilities with stringent availability requirements.
