FAQs

Yes. The MPS85N4VEAXX2H is a four-pole, fixed-vertical Magnum PXR frame designed for standard low voltage panels. It follows a fixed mounting footprint and matches common panelboard openings. Ensure adequate space for the four-pole unit and verify compatibility with the PXR20 LSIAM trip unit for proper coordination and protection.
Key specifications include a four-pole configuration with fixed vertical mounting, an 85 kA interrupting capacity, and a 5000 A fault-current rating (NNAABBCC). The PXR20 LSIAM electronic trip unit enables precise protection curves and zone selective interlocking. The unit supports UL Listed, CE Marked, and other major certifications to ease coordination with downstream protective devices.
Ideal for main distribution panels, switchgear, and motor feeder protection in industrial facilities. Its high interrupting capacity and four-pole design support power distribution in data centers and manufacturing lines. The PXR protection and compatibility with Power Xpert Protection Manager help optimize selective coordination and minimize downtime in complex electrical networks.
The breaker carries UL Listed, CE Marked, and ANSI Lloyd’s Register certifications, along with CSA, KEMA, ABS, DNV GL, and SABA Listed equivalents. These certifications support regulatory compliance across regions, aid supplier qualification, and simplify audits for multinational sites and projects.
Expected ROI comes from reduced nuisance trips, improved selective coordination, and extended asset life. Availability of renewal parts and integration with Power Xpert Protection Manager lowers maintenance costs and downtime. Regularly updating protection settings and leveraging documented manuals streamlines service tasks and supports faster fault diagnosis.
