Eaton PXM350MA6R21-4B4A Enclosed Meter - 0.2% C12.20
Part Number: PXM350MA6R21-4B4A
Quick Summary
An Eaton enclosed meter provides precise, multi-meter power monitoring for 3P/4W electrical distributions in industrial panels. This design addresses the common pain point of sprawling wiring and space constraints by integrating metering, fusing, and disconnects into a single enclosure. It carries CE marking along with ANSI/IEEE Std C12.20 (0.2% accuracy) and IEC 687 (0.2% accuracy) certifications to meet stringent reliability and compliance requirements. With 50/60 Hz operation and open communications like ModbusRTU and BACnet MSTP, it supports modern energy management and building automation. For installers and procurement teams, the compact footprint reduces installation time and long-term operating costs while delivering robust, compliant power monitoring in power management and distribution environments.
