FAQs

The MPSC163MEAXX2A uses a drawout vertical mounting with motorized racking, designed for standard frame switchgear. Plan for alignment with existing rails, ensure clearance for racking operation, and accommodate the 14.6 in depth, 16.8 in height, and 16.2 in width footprint. This setup reduces maintenance time and enhances safe breaker handling during replacements.
Key ratings include 1600 A frame current rating and 100 kA short-circuit current rating. Certifications include UL Listed, CE Marked, and NEMA Compliant, with additional third-party validation from Lloyd's Register and KEMA, supporting global compliance across markets.
Yes. The unit uses a PXR20 LSI trip unit that enables precise protection coordination. For optimal selective coordination, pair with compatible relays and design a coordination study to align trip curves with downstream protective devices, ensuring selective tripping while minimizing arc energy and downtime.
Renewal parts and accessories for Magnum PXR breakers are documented in Eaton’s renewal parts and accessories literature, including paper guides for low-voltage circuit breakers. Typical offerings cover replacement trip units, contact sets, and mechanism components to extend service life and reduce total cost of ownership.
The PXR20 LSI trip unit provides advanced, adjustable tripping logic that improves protection accuracy and reduces nuisance trips. It enables fast, safe clearance of faults with controlled arc energy, supporting safer operations and better protection coordination across motor loads and feeders.
