FAQs

The MPSC253HEAXX2S uses the Magnum PXR standard frame with fixed horizontal mounting for three-pole configurations. It fits in standard low-voltage switchgear enclosures and aligns with typical panel layouts, simplifying retrofits. Its 14.6 in depth, 16.8 in height, and 16.2 in width help planning space in existing racking. For new builds, verify enclosure clearance and busbar routing prior to installation.
This model delivers 2500 A Iu (rated uninterrupted current) and a 100 kAIC interrupt rating, suitable for high fault-current environments. The PXR25 LSIG ARMS trip unit provides advanced protection features, while the three-pole design supports robust three-phase protection. These ratings support reliable operation in data centers, heavy manufacturing, and critical processing lines.
Yes. With UL Listed, CE Marked, and CSA Certified certifications, plus Lloyd's Register and KEMA confirmations, the breaker meets stringent regulatory and safety requirements. Its high fault tolerance, selective coordination capabilities, and compatibility with Power Xpert Protection Manager make it well-suited for data centers, chemical plants, and other regulated environments requiring reliable protection and traceable compliance.
Eaton offers Magnum renewal parts and accessories designed to extend life and maintain performance for PXR-based assemblies. The availability of replacement trip units, wiring kits, and servicing literature (including manuals) supports proactive maintenance. Regular checks on Iu current, contact wear, and trap indicators help sustain reliability in continuous operation environments.
The MPSC253HEAXX2S is designed for seamless Power Xpert Protection Manager integration and works with PXR trip units. This enables centralized monitoring, event logging, and remote diagnostics, reducing mean time to repair and enabling proactive protection strategies across multiple panels and sites.
