Eaton PXM350MA6521-2B1AWS Enclosed Meter - 0.2% C12.20
Part Number: PXM350MA6521-2B1AWS
Quick Summary
Eaton enclosed meter provides accurate panel-level energy measurement for industrial electrical systems. In many facilities, limited space and retrofit complexity make metering projects costly and risky. The unit carries CE marking and ANSI/IEEE Std C12.20 (0.2% accuracy) plus IEC 687 (0.2% accuracy) certifications to ensure dependable readings and regulatory compliance. With Modbus RTU and BACnet MSTP communications, a 30 x 30 x 8 in NEMA 12 enclosure, and room for future expansion to multiple PXM modules, it delivers scalable energy management while simplifying integration into existing control architectures. The result is faster project delivery, reduced wiring complexity, and improved data accuracy for asset-intensive operations.
