The MPSC164VEAXX2S uses a Power Xpert Release (PXR) trip unit to deliver precise protection settings, improving coordination and reducing arc-flash risk in complex power networks. This translates to measurable business impact: fewer nuisance trips, enhanced motor protection, and smoother startup sequences for automated lines. In practice, the four-pole, fixed vertical mounting on a standard frame simplifies retrofits and maintenance across plant floors, enabling quick upgrades to existing panels and consistent protection across all feeders. With a 1600 A rating and 100 kA interrupt capacity, this breaker supports high-demand motor circuits and critical loads, delivering reliable short-circuit clearance and protecting valuable equipment. Compliance with UL, CE, and CSA standards assures auditors and customers of robust safety and regulatory alignment, while Power Xpert Protection Manager compatibility enables remote monitoring and event data analysis for proactive maintenance. The combination of documented specifications, accessory coverage, and Eaton support ecosystem reduces total cost of ownership and accelerates project timelines in power distribution upgrades.
