Eaton PXM350MA6521-2A4AW Enclosed Meter - NEMA12
Part Number: PXM350MA6521-2A4AW
Quick Summary
Eaton enclosed meter packs accurate power monitoring in a rugged enclosure for 3-phase, 4-wire electrical panels. Engineers often struggle with integration, space, and compliance when retrofitting metering in field installations. It delivers 0.2% accuracy per ANSI/IEEE C12.20 and IEC 687, supports ANSI/IEEE C62.41 surge guidance, and carries CE marking for international use. Coupled with Modbus RTU and BACnet MSTP communication, this meter streamlines data collection and supports scalable energy management. For panel builders and OEMs, the 4-meter configuration and separate CT shorting blocks simplify wiring, improve safety, and reduce installation time, delivering measurable OPEX savings in energized facilities.

Eaton Specification Sheet - PXM350MA6521-2A4AW
NEMA 12 enclosure with Window Kit provides industrial-grade protection while keeping the meter face visible for quick status checks. This reduces enclosure damage in dusty environments and minimizes maintenance downtime, making it ideal for control panels in manufacturing and packaging lines. The PXM350 family includes a separate CT shorting block per PXM and a separate fuse control power disconnect per PXM, which simplifies field wiring, enhances safety, and reduces commissioning time for complex metering layouts. A 3-phase/4-wire main fuse disconnect arrangement isolates power safely, lowering maintenance risk and improving uptime in critical processes. Four meters in a single unit and a Meter Faceplate display enable consolidated monitoring across multiple loads, streamlining panel design and diagnostics. Built-in Modbus RTU and BACnet MSTP enable seamless SCADA/BMS integration, delivering faster decision cycles and reducing integration costs. The unit’s 30”H x 30”W x 8”D footprint, 100 lb weight, and CE compliance align with standard industrial practices, supporting easier installation, shipping, and regulatory readiness. Designed for 120/240 V operation with a dedicated power supply, it minimizes external components and simplifies aftermarket servicing. In practice, installers benefit from clearer wiring, safer disconnections, and improved measurement visibility, while operators gain access to precise energy data and trend analysis for ongoing efficiency gains.
