FAQs

Begin with verifying the catalog number MPS85N3HEAXX2A and the three-pole, fixed horizontal mounting. Connect to the Power Xpert Protection Manager as per the quick start guide Mn013016en and PxR user manuals Mn013015en. Configure the PX R20 LSI trip unit settings to match system fault levels, enable zone selective interlocking if supported, and validate coordination with upstream and downstream devices to ensure selective tripping and minimal disruption during faults.
Key specs include a three-pole configuration, 85 kA interrupting capacity, 5000 A frame rating, and a PXR20 LSI trip unit. Dimensions show a compact footprint with length 16.3 in, height 16.8 in, and width 31.1 in, and a weight of 237 lb. The unit is CE marked, UL Listed, and CSA Certified, suitable for panelboards and MCCs in demanding industrial environments.
Yes. The Magnum PXR with PXR20 LSI trip unit supports precise coordination, rapid tripping on fault conditions, and arc energy reduction techniques. For best results, perform selective coordination studies and apply Zone Selective Interlocking (ZSI) where feasible, using the application papers and guidelines provided by Eaton to validate your scheme in MCCs, motor feeders, and critical process lines.
This breaker carries UL Listed, CE Marked, and CSA Certified status, along with NEMA compliance and other certifications. These credentials help satisfy regulatory audits, facilitate cross-border deployments, and support customer compliance programs for industrial installations, panel manufacturers, and end users requiring converged safety and performance guarantees.
Lifecycle considerations include periodic inspection of trip unit health, firmware or protection-set updates via the Power Xpert Manager, and verified calibration of the LSI protection functions. ROI benefits come from improved downtime reduction, reduced arc energy risk, faster commissioning, and easier upgrades to protection schemes, which translate to lower maintenance costs and higher uptime in mission-critical processes.
