Eaton PXM4051A1BB-2B-ASL Enclosed Meter - NEMA12
Part Number: PXM4051A1BB-2B-ASL
Quick Summary
Eaton enclosed meter is a compact panel-mounted metering solution for 3-phase, 4-wire systems in industrial facilities. Facilities often struggle to obtain clear energy data, secure connectivity, and reliable operation from disparate meters. This enclosure carries ANSI/IEEE Std C12.20 (0.2% accuracy) and IEC 687 (0.2% accuracy) certifications, with CE marking to support global compliance. By offering ModbusRTU/TCP, BACnet/IP, and a WebUI, it enables seamless, data-driven decisions for energy management. Its robust design and integrated disconnect simplify installation, maintenance, and long-term reliability in demanding environments while supporting scalable panel metering and industrial automation workflows.

Eaton Specification Sheet - PXM4051A1BB-2B-ASL
Fused main disconnect on the door provides a lockable, safe isolation point, reducing outage risk during maintenance and speeding up service windows for plant lines, which translates to lower downtime costs. The single-meter enclosure design minimizes wiring complexity and accelerates commissioning, delivering faster time-to-value for energy monitoring projects and building management system integrations. The NEMA 12 enclosure and compact footprint (30 in H x 24 in W x 12 in D, 100 lb) fit standard electrical rooms and cabinets, saving space and reducing installation costs. Built-in ModbusRTU/TCP, BACnet/IP, and WebUI enable out-of-the-box EMS and BMS connectivity, supporting real-time energy visibility, demand management, and predictive maintenance. Combined with the 480 Vac rating and 50/60 Hz compatibility, this meter is ready for diverse industrial environments while addressing common objections about interoperability and retrofit feasibility. This unit is well-suited for panel metering in manufacturing, food & beverage, and process facilities seeking reliable energy data for operation optimization and cost control.
