FAQs
Installation begins with selecting a compliant indoor or covered outdoor location and securing the NEMA 3R enclosure. Mount the unit on a stable surface, connect the 480V bus lines to the meter inputs, and wire the 120/240 Vac power supply as specified. Configure Modbus addressing and verify clearance for reading access. Follow standard electrical safety practices and reference Eaton's installation sheet to ensure accurate phase wiring, burden considerations, and fuse/disconnect alignment.
This meter meets ANSI/IEEE Std C12.20 with 0.2% accuracy and IEC 687 (0.2% accuracy), along with ANSI/IEEE C62.41. It is CE marked for European compliance. These certifications support revenue-grade measurement, regulatory reporting, and reliability in critical environments, helping you demonstrate measurement integrity during audits and grid reporting.
Yes. The PXM350MA6121-3A2A supports Modbus communication, enabling seamless integration with SCADA, EMS, and other energy analytics platforms. With two meters in a single enclosure, you can aggregate and route data efficiently, reducing wiring complexity and easing commissioning in a multi-panel facility.
The unit features a NEMA 3R enclosure, designed for outdoor use under covered areas and indoor spaces with exposure to dust or incidental moisture. This protects critical metering electronics while simplifying installation in factory exteriors, equipment rooms, and protected outdoor walkways, lowering enclosure-related maintenance risks.
By providing dual metering, remote Modbus connectivity, and robust protection, the PXM350MA6121-3A2A improves energy visibility and reduces field visits for data collection. The result is faster fault diagnosis, enhanced energy optimization, and lower operational costs. Routine checks focus on ensuring clean wiring, calibration verification, and Modbus channel health to sustain accuracy over time.
