FAQs

To install, ensure panel compatibility with drawout vertical mounting and a three-pole configuration. Position the breaker in the designated drawout frame, engage the bus bars, and secure with the appropriate mounting hardware. Attach the PXR20 LSIG trip unit, verify clearances, torque mounting fasteners to the manufacturer’s specification, and program surge and trip settings per NEC/IEEE guidelines. Conduct a functional test before commissioning.
The MPS85N3WEAXX2C provides an 85 kA short-circuit rating, suitable for demanding motor and feeder protection in industrial settings. With a three-pole design and drawout mounting, it supports effective coordination in switchgear and MCCs, reducing arc exposure and improving motor start protection. Always verify voltage, system fault levels, and coordination curves for specific motor load profiles.
Yes. The MPS85N3WEAXX2C uses a Power Xpert Release (PXR) trip unit that integrates with Power Xpert Protection Manager for centralized protection management, monitoring, and diagnostics. This enables remote fault analytics, settings optimization, and streamlined maintenance planning across plant-wide protection architectures.
The breaker carries UL Listed, CE Marked, ANSI, CSA, and other certifications (including Lloyd’s Register and KEMA). These credentials support regulatory compliance, international procurement, and safety approvals. For regulated industries such as data centers or chemical processing, these certifications simplify audits, supplier qualification, and cross-border installations.
The PXR20 LSIG trip unit enables precise protection coordination and remote diagnostics through Power Xpert tools, reducing on-site maintenance visits and accelerating fault resolution. Over time, this lowers total cost of ownership by minimizing unplanned outages, extending component life, and improving uptime for critical processes in manufacturing and utilities environments.
