Eaton Magnum MPSC504HEAXX2A features a four-pole Magnum PXR frame with a PXR20 LSI trip unit and a double-standard frame designed for fixed horizontal mounting. This combination enables precise, selective coordination and simpler installation in large panel assemblies, reducing risk of unnecessary outages and improving uptime in critical facilities. In practice, that translates to faster fault clearance and easier maintenance planning, especially in data centers and heavy manufacturing environments that demand quick isolation without compromising downstream equipment protection. The unit’s UL Listed, CE Marked, and NEMA Compliant status supports multi-region procurement and regulatory conformity, streamlining sourcing and reducing compliance risk. With a substantial footprint and robust build, it supports long service life in harsh industrial settings while providing compatibility with renewal parts and Eaton’s service ecosystem. Operators gain clearer visibility into protection schemes and easier integration with Power Xpert Protection Manager for centralized protection coordination. This also aligns with industry best practices for zone selective interlocking and advanced protective coordination in modern switchgear.

FAQs

The MPSC504HEAXX2A uses a fixed horizontal mounting on a double-standard frame and is designed for four-pole configurations. Verify panel clearance for a 16.3 in depth, 16.8 in height, and 44.1 in width footprint, and ensure busbar alignment with the 5000 A Iu rating. Follow the Magnum PXR installation guidelines to enable proper trip-unit configuration and secure mounting while maintaining required clearances for heat dissipation and service access.
This breaker provides a rated uninterrupted current (Iu) of 5000 A and an interrupt rating of 100 kAIC. These specifications enable protection in high-current systems and ensure fast fault interruption to limit damage. For designs with high fault currents, confirm system coordination with upstream devices and ensure the PXR20 LSI trip unit is configured to achieve selective protection without unnecessary outages.
Yes. The four-pole Magnum PXR with a PXR20 LSI trip unit is well-suited for motor control centers and large panelboards. Its high Iu and 100 kAIC ratings support motor protection in demanding environments, while the PXR protection logic enables selective coordination. When integrating into MCCs, ensure proper wiring, mounting alignment, and compatibility with Power Xpert Protection Manager as part of a broader protection strategy.
The MPSC504HEAXX2A carries UL Listed, CE Marked, and NEMA Compliant status, along with additional certifications such as CSA, KEMA, Lloyd's Register, ABS, DNV GL, and CSA/ANSI where applicable. These certifications support cross-border procurement and compliance with global electrical standards, reducing certification cycles for multinational projects.
With Power Xpert Release compatibility and the robust Magnum PXR format, maintenance intervals can be optimized through accurate trip-unit configurations and reliable fault isolation. The device’s durability (heavy-duty frame, 319 lb weight, and substantial enclosure) supports longer service life in harsh environments, delivering ROI via reduced downtime, predictable maintenance, and streamlined spare-part provisioning through Eaton’s renewal-part ecosystem.
