FAQs

The MPS84A4VEAXX2A uses a fixed vertical mounting and a four-pole configuration, designed for straightforward insertion into standard 3‑phase panels. Verify alignment with bus bars and utilize the catalog data for dimensions (16.3 in depth, 16.8 in height, 44.1 in width). The PXR20 upgrade path allows field configuration changes without major rework, reducing commissioning time and minimizing startup risk.
Key specs include a 4000 A current rating, 85 kA short-circuit rating, four-pole configuration, fixed vertical mounting, and the PXR20 LSI trip unit. The unit is UL Listed and CE Marked, with additional ANSI/KEMA and other certifications. These values support robust fault tolerance, higher reliability, and regional compliance in diverse facilities.
Yes. The four-pole design supports three‑phase systems typical in motor protection schemes, while the PXR20 trip unit provides precise coordination and adjustable protection curves. This combination helps prevent nuisance trips on starting transients, improves uptime for conveyors and presses, and supports scalable protection for evolving motor control centers.
The MPS84A4VEAXX2A carries UL Listed and CE Marked certifications, plus ANSI, KEMA, Lloyd's Register, CSA, ABS, and DNV GL approvals. NEMA compliance and CCC Marking further support US, European, and global deployments, reducing procurement risk and enabling smoother cross-border installation and maintenance.
Upgrading to the PXR20 enables selective protection and coordinated protection schemes, reducing outage risk and MTTR. It also supports remote diagnostics via Eaton's protection manager, simplifying maintenance planning and asset management. The availability of renewal parts and comprehensive manuals further lowers lifecycle costs by simplifying replacements and updates.
