FAQs

The MPSC164HEAXX2S employs the PXR25 LSIGAM trip unit and is designed for seamless integration with Eaton's Power Xpert Protection Manager. This compatibility enables centralized configuration, real-time monitoring, and easier upgrade paths for selective coordination across feeders. For new installations, you can plan protection schemes that align with existing PXR devices and migration strategies when expanding switchgear networks.
Fixed horizontal mounting supports stable bus bar alignment and straightforward wiring routes, reducing field assembly time. The four-pole design fits standard Magnum frames and enclosure footprints, allowing predictable clearances and easier access for maintenance. Ensure mounting brackets and access room align with the 14.6 in depth, 16.8 in height, and 21.2 in width specifications, and verify compatibility with downstream devices in the cabinet.
Yes. The MPSC164HEAXX2S is rated for 100 kA short-circuit capability and 1600 A continuous current, which supports selective coordination strategies in medium- to large-size distribution schemes. For optimal performance, coordinate with downstream protection devices, verify arc-flash considerations, and leverage the PXR25 LSIGAM trip unit’s settings to maintain selectivity across levels.
The unit carries UL Listed, CE Marked, and NEMA Compliant certifications, with additional KEMA, ANSI, CSA, DNV GL, ABS, and Lloyd's Register certifications available. This broad certification profile supports global deployments, assists with meeting local electrical codes, and reduces procurement risk for multinational projects.
Maintenance benefits come from standardized Magnum components, the PXR trip unit for straightforward field configuration, and compatibility with Power Xpert tools for remote diagnostics. Although initial costs may be higher than basic breakers, the protection reliability, reduced downtime, and easier upgrades can yield favorable total cost of ownership over the equipment life cycle.
