FAQs
For installation, verify the enclosure footprint matches the 20inW x 24inH x 14.1inD dimensions and plan for a 100 lb weight. Mount the unit in a suitable NEMA 3R-rated location, ensure proper clearance for wiring, and supply it with the 100-415 Vac/100-300 Vdc range. Use three phase connections for the three meters and connect Modbus RTU or BACnet MSTP as required. Follow local codes and provide proper labeling for rapid maintenance.
The PXM350MA6321-3B3A delivers 0.2% accuracy per ANSI/IEEE Std C12.20, with compatibility to IEC 687 as noted in its certifications. It carries CE marking for compliance and protection against environmental conditions. This combination supports revenue-grade metering, precise energy accounting, and dependable performance across varying loads and voltages typical in industrial facilities.
Yes. The meter supports both Modbus RTU and BACnet MSTP communication protocols, enabling seamless integration with popular SCADA and BMS systems. This interoperability allows centralized energy monitoring, data logging, and real-time control actions without custom gateways, reducing integration risk and accelerating project timelines.
By delivering accurate, tri-channel energy data in a rugged enclosure, the meter reduces billing discrepancies and improves demand-management capabilities. Its durable construction lowers maintenance costs in outdoor or harsh environments, while standard communication interfaces minimize integration expenses. The result is faster payback through improved energy visibility, reduced outages, and better operational decision-making.
Best-fit applications include industrial control panels, commercial building energy management, and utility-grade monitoring of three feeders. It suits facilities needing reliable multi-channel metering with integrated display, TOU support, and modular integration via Modbus RTU or BACnet MSTP, enabling accurate energy accounting, scalable monitoring, and efficient demand response.
