Eaton enclosed meter PXM350MA6521-2B2AWS - NEMA12 480V
Part Number: PXM350MA6521-2B2AWS
Quick Summary
Eaton enclosed meter is a rugged energy metering solution for panel-level monitoring in industrial facilities. Engineers often struggle with space constraints, future expansion, and reliable data in compact panel enclosures. This unit carries CE marking and ANSI/IEEE C12.20 (0.2% accuracy) and IEC 687 (0.2% accuracy) certifications to support precise energy measurement and regulatory compliance. The dual-meter design, ModbusRTU and BACnet MSTP connectivity, and a compact NEMA 12 enclosure help reduce wiring, simplify commissioning, and accelerate asset monitoring across facilities. For developers and maintenance teams, it also enables scalable energy accounting, straightforward integration with existing SCADA systems, and improved total cost of ownership over time.

Eaton Specification Sheet - PXM350MA6521-2B2AWS
Dual meters in one enclosure provides two measurement channels in a single footprint, reducing cabinet space and simplifying wiring. Business impact includes lower installation costs and faster commissioning, especially in retrofit projects with tight footprints. This configuration is ideal for multi-line panels and utility rooms where energy usage must be tracked per circuit with minimal cabinet intrusion. The NEMA 12 enclosure with a 30 in H x 30 in W x 8 in D footprint and a 100 lb weight offers rugged protection against dust and light moisture, enabling reliable operation on manufacturing floors and in control rooms. Space-efficient expansion is supported by accommodations for future 2-PXM350MA6521 installations and separate CT shorting blocks per PXM, plus a dedicated Fuse Control Power Disconnect per PXM for safer maintenance. Local display via Meter Faceplate provides clear, on-site readings; two meters support per-feeder energy accounting. Standard communication via ModbusRTU and BACnet MSTP enables straightforward SCADA and building management integration, reducing integration time and risk. Certifications including CE marking and ANSI/IEEE C12.20 (0.2% accuracy) plus IEC 687 (0.2% accuracy) deliver regulatory confidence and traceable measurement, supporting compliance, audit readiness, and long-term reliability.

FAQs
Installers should plan for a 30 in x 30 in x 8 in footprint in a NEMA 12 environment, with a total weight around 100 lb. The unit supports two PXM350 meters with separate CT shorting blocks and per-PXM fuse control power disconnects, enabling safe maintenance and future expansion to a second meter. Ensure 480 VAC service and proper clearance for access to the meter faceplate and wiring terminations.
The device adheres to ANSI/IEEE Std C12.20 and IEC 687 with an accuracy of 0.2%. It is designed for three-phase, four-wire systems and supports a 480 VAC power supply. With two meters in a single enclosure, energy data per feeder remains precise, facilitating accurate billing, monitoring, and performance analysis.
Yes. The enclosure provides built-in support for ModbusRTU and BACnet MSTP, enabling seamless integration with standard SCADA and building management systems. This compatibility reduces integration risk, speeds up data acquisition, and improves real-time energy visibility across manufacturing cells or facility utilities.
Ideal for panel boards with two feeders, manufacturing lines needing per-circuit energy accounting, and utility rooms requiring compact, scalable energy monitoring. The dual-meter approach reduces cabinet space and wiring complexity while preserving measurement granularity, supporting cost-effective energy management and maintenance planning.
ROI improves through reduced cabinet footprint, simpler wiring, and faster commissioning, translating to lower labor and material costs. Maintenance is streamlined by independent CT blocks and separate fuse disconnects per meter, minimizing downtime during testing or expansion. Compliance with CE, ANSI/IEEE, and IEC standards also reduces audit risk and long-term reliability concerns.
