The external meter module with 333 mV CT inputs enables precise current sensing across single-phase and three-phase systems. This reduces measurement error and improves billing accuracy, supporting more effective demand management. It is ideal for distribution panels in manufacturing plants, data centers, and large commercial facilities. Wide voltage compatibility of 277V L-N and 480V L-L ratings allows use across mixed systems without proxy transformers. This saves installation time and reduces equipment costs while enabling consistent monitoring across sites. Applications include facilities with mixed voltage infrastructure. Communications options include Modbus TCP and Modbus RTU (RS-485) supporting easy integration with PLCs and SCADA systems. The result is simplified wiring and faster deployment, lowering total cost of ownership. This compatibility is critical for multi-building campuses and data centers. Compliance and ruggedness are reinforced by UL Listed 61010-1, ANSI/IEEE C12.20, and EN 61000-4-4/5 protections, delivering reliable operation even in harsh electrical environments. A one-year warranty and extensive Eaton documentation support fast commissioning and long-term maintenance. Installation and compatibility with the PXBCM-MB base mean the unit slots into the Power Xpert monitoring ecosystem with minimal downtime. Installation guides IL150002EN and the system datasheets streamline setup and validation, while ongoing firmware updates keep the device current. Data capabilities include Wh Net, per-phase current and voltage, Watts, VA, and Watt Demand, delivering comprehensive energy visibility to drive optimization and regulatory reporting.
