Eaton PXM350MA6521-2A3A Enclosed Meter - NEMA12
Part Number: PXM350MA6521-2A3A
Quick Summary
Eaton enclosed meter provides panel-mounted energy measurement for industrial facilities and commercial buildings. This compact meter consolidates three measurement points in a single enclosure, simplifying installation and reducing wiring complexity. Many operators struggle with space constraints and CT wiring errors in traditional metering setups; the design combines CT shorting blocks with a dedicated control power disconnect per PXM to streamline commissioning and improve safety. The unit features a NEMA 12 enclosure and 120/240V power, ready for indoor environments supporting 50/60 Hz operation. With ModbusRTU and BACnet MSTP communications, energy data integrates into existing BAS/SCADA systems to enable real-time visibility, regulatory compliance, and a clearer path to optimizing energy use and total cost of ownership.

FAQs
Installers should plan for indoor mounting with adequate clearances around the 30inH x 20inW x 8inD enclosure. Ensure the CTs are correctly routed to the separate CT shorting block per PXM and connect the 120/240V power supply to the main disconnect. Verify 50/60 Hz compatibility and secure meter faceplate wiring before commissioning to minimize field wiring errors and facilitate safe startup.
The unit provides three meters within a single enclosure for 1-3 phase/4-wire systems, with ModbusRTU and BACnet MSTP communications for BAS/SCADA integration. This enables centralized data collection, real-time energy monitoring, and scalable reporting, reducing data silos and supporting advanced energy management initiatives across facilities.
Yes, it is designed with a NEMA 12 enclosure to protect internal components from dust and light splashes in indoor electrical rooms. While not specified for outdoor use, the indoor-rated enclosure provides rugged protection for controlled environments, improving reliability and extending service life in standard facility spaces.
Consolidating three measurement points into one enclosure reduces installation time and wiring costs, while integrated CT blocks and safety disconnects minimize commissioning risk. The ModbusRTU/BACnet MSTP interface enables real-time energy visibility, supporting demand management and predictive maintenance, which translates to lower energy bills and improved operational efficiency over the lifecycle.
The PXM350MA6521-2A3A uses a 120/240V supply, operates at 50/60 Hz, and employs a NEMA 12 enclosure for indoor protection. It supports ModbusRTU and BACnet MSTP and provides three meters in one enclosure, making it compatible with standard industrial control panels and BAS/SCADA systems for integrated energy management.
