FAQs

When installing the Eaton Magnum MPS85N3MEAXX2F, ensure vertical drawout mounting space is clear for motorized racking and that panel enclosures accommodate the 16.3 in depth, 16.8 in height, and 31.1 in width footprint. Verify clearance for operating handles, wiring, and protection equipment, and consult the Quick Start and breaker manuals to align the protection settings with existing protection schemes.
Key specs to confirm include three-pole operation with the PXR20 LSIGAM trip unit, interruption rating of 85 kA, and a withstand rating of 5000 A (AABBCC). Dimensions are 16.3 in depth, 16.8 in height, and 31.1 in width, with a weight of 237 lb. Ensure compatibility with control panels, MCCs, and motor loads in your application.
Yes. The PXR trip unit and Magnum frame are designed to enable selective coordination when paired with appropriate protection strategies. For best results, refer to selective coordination application papers and the Magnum PXr product aids, and use time-current curves to align settings across upstream and downstream devices.
The MPS85N3MEAXX2F carries UL Listed status and CE marking, plus ANSI, Lloyd's Register, KEMA, CSA, ABS, and DNV GL certifications. It also aligns with CCC Marked and NEMA compliance, SABA listing, and other international standards, easing procurement and inter-market deployment.
The combination of a motorized racking system, rapid drawout maintenance, and a PXr trip unit reduces maintenance time and unplanned downtime. The availability of renewal parts, compatibility with Power Xpert Protection Manager, and extended service life translate into lower lifecycle costs and improved plant uptime over traditional solutions.
