Environmental protection and rugged enclosure: The PXM350MA6321-4A1A arrives in a NEMA 4X enclosure that seals against water, dust, and corrosive exposure, reducing field maintenance and unplanned downtime. This design keeps critical meters functioning in washdown zones, outdoor panels, and aggressive industrial environments where reliability is essential. By selecting a meter with proven enclosure integrity, maintenance teams report fewer field service calls and longer mean time between failures in continuous process applications. Wide voltage compatibility and straightforward wiring: The meter operates from 120-240 VAC and supports 50/60 Hz systems, enabling direct integration with most exchange-ready power designs. This reduces transformer needs, simplifies panel layouts, and speeds commissioning in retrofit projects. For retrofit and new-build deployments, the unit minimizes wiring complexity and supports rapid, error-free installations.

FAQs
Installers should mount the 24”H x 16”W x 8”D enclosure in a suitable electrical room, connect the 120-240 VAC supply within the main panel, and wire the meter to a 3-phase, 4-wire system as specified. Use the faceplate display for initial readings and configure ModbusRTU or BACnet MSTP communication through the standard terminals. The rugged NEMA 4X enclosure supports washdowns and outdoor locations, reducing field rework and rerouting.
The device operates on 120-240 VAC with 50/60 Hz frequency and delivers ANSI/IEEE C12.20 accuracy at 0.2%, IEC 687 at 0.2%, and ANSI/IEEE C62.41 surge performance. It includes a single meter in a NEMA 4X enclosure, 16 in depth, 24 in width, and 8 in height, with a 100 lb weight, suitable for robust industrial applications.
Yes. The PXM350MA6321-4A1A is designed for 3-phase, 4-wire systems and main fused disconnect configurations, making it a strong fit for industrial facilities that require reliable, centralized energy measurement and reporting across multiple feeders.
The meter is CE marked and compliant with ANSI/IEEE Std C12.20 (0.2% accuracy), ANSI/IEEE Std C62.41, and IEC 687 (0.2% accuracy), ensuring regulatory alignment and accurate energy data suitable for audits, billing, and energy analytics.
The rugged enclosure and high-accuracy metering reduce maintenance frequency and data errors, while ModbusRTU and BACnet MSTP support streamline integration with EMS/SCADA systems. This leads to faster fault isolation, improved energy visibility, and potentially lower operating costs over the life of the installation.
