Eaton PXM350MA6321-3A3A Enclosed Meter - ANSI/IEEE 0.2% Accuracy
Part Number: PXM350MA6321-3A3A
Quick Summary
Eaton enclosed meter measures electrical energy for industrial and commercial power systems. Design engineers often wrestle with installation crowding, wiring complexity, and the need for reliable, multi-channel metering. Built to CE Marked standards with ANSI/IEEE Std C12.20 (0.2% accuracy), ANSI/IEEE Std C62.41, and IEC 687 (0.2% accuracy), this unit delivers precise monitoring and robust protection. With a 3-channel enclosure, Modbus RTU and BACnet MSTP communications, TOU support, and a pulse output, it integrates quickly into EMS workflows. The result is improved energy visibility, reduced wiring complexity, and lower total cost of ownership for industrial plants and large facilities. Its rugged NEMA 3R design and common voltage features simplify installation in challenging environments.

FAQs
Yes. The PXM350MA6321-3A3A is designed for integration into standard electrical enclosures and uses a rugged NEMA 3R chassis suitable for indoor and outdoor installations. Its dimensions (20in W x 24in H x 14.1in D) and 100 lb weight should be planned for a dedicated space. It supports three meters in one enclosure and includes features like a common voltage disc and separate CTSB per PXM to simplify wiring. Ensure accessibility for service, proper clearance for heat dissipation, and alignment with existing ModbusRTU or BACnet MSTP networks.
The meter offers ANSI/IEEE Std C12.20 accuracy of 0.2%, with voltage ratings of 400Vac L-N and 690Vac L-L. It is powered by a versatile 100-415 Vac / 100-300 Vdc supply and operates at 50-60 Hz. Communication options include Modbus RTU and BACnet MSTP, enabling straightforward integration with energy management systems and building automation platforms.
Industries with distributed energy systems, large commercial buildings, and industrial facilities benefit most. The three-channel measurement, TOU support, pulse output, and EMS compatibility support precise energy accounting, demand management, and utility-grade reporting for panels, switchgear, and multi-branch feeders.
This Eaton enclosed meter is CE marked and certified to ANSI/IEEE Std C12.20 (0.2% accuracy), ANSI/IEEE Std C62.41, and IEC 687 (0.2% accuracy), ensuring regulatory compliance and reliable performance in critical power applications.
Benefits include reduced wiring complexity, consolidated monitoring of three meters in a single enclosure, and improved energy visibility through Modbus/BACnet connectivity and TOU. The rugged enclosure supports long service life in challenging environments, lowering maintenance costs while enabling better energy management, faster fault detection, and meaningful ROI through energy savings and optimized demand response.
