FAQs

The MPS85N4MEAXX2H uses a drawout vertical mounting with a motorized racking system that simplifies insertion and removal. Ensure the breaker is seated in the switchgear frame, connect line and load terminals per the Eaton user manual MN013016EN, and enable motorized racking only after all safety interlocks are verified. This reduces time on site while preserving operator safety.
Verify catalog number MPS85N4MEAXX2H, four-pole configuration, 85 kA interrupting capacity, 16.3 in depth, 16.8 in height, 44.1 in width, and 319 lb weight. Confirm PXR20 LSIAM trip unit compatibility, drawout mounting, and that the panel or MCC frame supports a Magnum double standard frame unit with motorized racking.
Yes. The Magnum MPS85N4MEAXX2H with PXR20 LSIAM trip logic supports selective coordination strategies by enabling precise trip settings and coordination curves. When paired with correctly tuned upstream devices and proper device grouping, it improves fault isolation, reduces arc flash exposure, and optimizes uptime in motor-driven processes.
This unit is UL Listed, CE Marked, and NEMA Compliant, with additional certifications including ANSI, CSA, DNV GL, Lloyd's Register, KEMA, and ABS. The diverse certification set helps streamline procurement across regions and simplifies compliance during audits and installation in regulated industries.
Expect reduced downtime due to motorized racking, easier maintenance access, and longer service life from robust construction. The PXR20 trip unit provides diagnostic data and stable protection, enabling preventive maintenance and improved asset utilization.
