Eaton Specification Sheet - PXM350MA6521-3A1A
The NEMA 3R enclosure and rugged housing protect the meter in outdoor or harsh indoor environments, reducing field maintenance and extending service life. This configuration is ideal for outdoor substations and building entrances where weather and vandalism are concerns. The 3PH/4W main fused voltage disconnect and CT shorting block simplify installation and safety during commissioning, enabling a single-box metering solution for robust energy measurement and reducing wiring errors during startup. Modbus communication provides seamless integration with existing SCADA and building management systems, centralizing energy data and enabling real-time monitoring to improve outage response and energy planning. The 1-meter faceplate display delivers quick local readings, minimizing the need for handheld meters and speeding off-site checks. High-precision measurements (0.2% accuracy per ANSI/IEEE C12.20 and IEC 687, CE marking) support accurate billing, compliance reporting, and audit trails across industrial and commercial sites. With a flexible 120/240 Vac power supply and 50/60 Hz compatibility, this meter supports deployment in diverse facilities, from manufacturing floors to data centers, while preserving compatibility with legacy panels and newer switchgear.
