Eaton PXM350MA6321-2B1C Enclosed Meter - CE Marked
Part Number: PXM350MA6321-2B1C
Quick Summary
An Eaton enclosed meter delivers precise power metering for industrial panels and plant power distribution. It provides accurate energy readings essential for energy management, system optimization, and regulatory compliance. Many engineers struggle with bulky installations, wiring complexity, and readings that drift in dusty or humid enclosures; this unit is designed to thrive in such environments with a robust NEMA 12 enclosure, a 480 Vac power supply, and a single-meter configuration. Featuring CE marking and certifications to ANSI/IEEE C12.20 (0.2% accuracy) and IEC 687 (0.2% accuracy), it supports reliable, traceable measurements across 50/60 Hz networks. For teams pursuing tighter energy control and better asset utilization, it offers straightforward RS485 connectivity to PXG/PXM350 systems and an integrated power solution that reduces installation time and total cost of ownership.

Eaton Specification Sheet - PXM350MA6321-2B1C
Paragraph 1: The NEMA 12 enclosure protects the meter from dust, spray, and incidental moisture, extending lifespan in manufacturing floors and service bays. Business impact: fewer maintenance cycles, lower downtime, and predictable performance in harsh environments. Application: ideal for control panels and distributed power centers where cleanliness and resilience are critical. Paragraph 2: The unit supports 480 Vac, 3-phase, 4-wire configurations with a main fused disconnect, meeting common industrial distribution standards. Business impact: streamlined protection and metering in a single chassis, reducing cassette count and wiring complexity. Application: plant wide energy monitoring and machine-level power profiling. Paragraph 3: RS485 connectivity to PXG COM 1 and a Vdc power supply for PXG simplify integration with Eaton PXG/PXM350 ecosystems. Business impact: faster commissioning, fewer cable runs, and improved data reliability. Application: scalable energy management and remote monitoring across multiple panels. Paragraph 4: Compact footprint (24 in H x 20 in W x 8 in D) and single-face display enable quick visibility and easy installation. Business impact: accelerated project timelines and lower labor costs. Application: panel upgrades and new installations requiring a ready-to-read energy meter. Paragraph 5: Certifications and compliance (CE Marked; ANSI/IEEE C12.20 0.2%; IEC 687 0.2%) provide regulatory confidence and audit readiness. Business impact: easier regulatory alignment and safer asset documentation. Application: facilities with stringent quality and safety expectations. Paragraph 6: Real-world insight from field deployments shows the value of integrating protection, metering, and communication in one enclosure; installers report reduced wiring errors and faster fault isolation. Application: manufacturing lines and data centers seeking reliability and traceability in energy data.

FAQs
Installation leverages the RS485 to PXG COM1 interface and the Vdc power supply for PXG. Mount the 24"H x 20"W x 8"D enclosure in a clean, accessible panel space, connect 480 Vac 3-phase power to the main fused disconnect, and wire RS485 to the PXG COM1 port. This minimizes wiring complexity and speeds commissioning while preserving measurement accuracy.
The meter operates with 480 Vac power, supports 50/60 Hz, and is configured for 3-phase, 4-wire systems. It includes a 1-meter configuration, a NEMA 12 enclosure, and a meter faceplate display for easy on-site reading. Certifications include CE Marked and ANSI/IEEE Std C12.20 (0.2% accuracy) alongside IEC 687 (0.2% accuracy).
Yes. The PXM350MA6321-2B1C is designed for 480 Vac 3-phase/4-wire systems in commercial and industrial settings, with a fused main disconnect and a robust NEMA 12 enclosure. It provides accurate energy data at 50/60 Hz and supports RS485 communications for integration with Eaton PXG/PXM350 family systems.
It is CE Marked and certified to ANSI/IEEE Std C12.20 (0.2% accuracy) and IEC 687 (0.2% accuracy). These certifications ensure regulatory compliance, measurement reliability, and consistency across international installations, reducing audit risk and supporting precise energy accounting for utility reporting and facility management.
ROI benefits come from integrated protection and metering reducing wiring, faster commissioning, and centralized data collection for energy management. Maintenance is simplified due to a single enclosure with protective hardware, reducing parts count and service time. Field performance is enhanced by 0.2% accuracy and robust CE/IEC certifications in demanding environments.
