FAQs

Yes. MPS86A4MEAXX2A supports the Power Xpert Release (PXR) family, including the PXR20 LSI trip unit, and features a drawout vertical design with motorized racking. This combination enables selective protection, faster maintenance, and safer breaker exchanges in switchgear and panel layouts typical of industrial automation environments.
Key ratings include a 6000 A current rating (NABCNABC) and an 85 kA short-circuit withstand, four-pole construction, and fan-cooled cooling. These specifications support high-energy fault management, robust motor drive protection, and reliable operation across demanding industrial distribution panels.
Industrial automation projects, motor control centers, and power distribution panels with high fault-current environments benefit most. The four-pole, drawout design paired with motorized racking enables rapid maintenance, while the PXR20 LSI trip unit provides scalable protection coordination for complex automation systems.
This breaker is UL Listed and CE Marked, with additional compliance such as NEMA standards, CCC Marked, SABA Listed, and auxiliary certifications. The combination supports global procurement, regulatory compliance, and installation in multinational facilities.
The motorized racking and high-accuracy PXR20 LSI trip unit reduce downtime and nuisance trips, enabling faster service and precise protection. This improves equipment uptime, extends component life, lowers maintenance labor costs, and yields a lower total cost of ownership in manufacturing and process environments.
