FAQs

The MPS85N3VEAXX2H is designed for fixed vertical mounting within Magnum frame systems and supports a double standard frame. Ensure the three-pole configuration aligns with your bus and enclosure dimensions (16.3 in L, 16.8 in H, 31.1 in W) and verify connection through the PXR20 LSI ARMS trip unit. Pre-check torque specs and mounting hardware to minimize commissioning time.
PXR20 LSI ARMS refers to a Power Xpert Release trip unit with load-shedding and arc-flash mitigation features. It improves protection selectivity by coordinating with upstream relays to isolate only the faulty section, reducing energy exposure and downtime. This is particularly beneficial in large or complex switchgear where selective tripping is critical.
Yes. With 85 kAIC interrupt rating and 5000 A Iu, it supports high fault-current environments typical of data centers and manufacturing lines. Its Magnum PXR trip unit enables precise coordination, while its robust certifications simplify compliance and procurement across multiple facilities.
Key certifications include UL Listed, ANSI Certified, CSA Certified, CE Marked, and additional approvals from NEMA, KEMA, DNV GL, and other bodies. This combination supports global deployment, smoother supplier qualification, and easier proof of conformity during audits.
The combination of high fault-current handling, selective coordination, and seamless monitoring via Power Xpert Protection Manager reduces downtime and maintenance overhead. Though initial costs may be higher, the long-term savings come from fewer outages, faster fault isolation, and data-driven maintenance planning.
