FAQs
The device uses a 120-240 VAC power supply and a 3P4W mains configuration with a main fused disconnect. Mount the NEMA 3R enclosure on a stable surface, connect the three phase lines and neutral to the labeled lugs, and link the RS485 to PXG COM1 for communication. The PXG compatibility simplifies integration with existing Eaton energy management networks and minimizes rework during commissioning.
Core specs include three meters, 50/60 Hz operation, 120-240 VAC power input, NEMA 3R enclosure, and a 24"x24"x10" footprint with a 100 lb weight. The meter delivers ANSI/IEEE Std C12.20 (0.2% accuracy) and IEC 687 compliance, with CE marking, ensuring accurate energy measurement and regulatory alignment in demanding environments.
Yes. The NEMA 3R enclosure provides weather resistance suitable for outdoor or semi-outdoor installation, while the 120-240 VAC power supply and RS485 connectivity support robust, scalable monitoring. It’s well-suited for utility feeders, manufacturing lines, and facilities requiring reliable energy data across multiple loads.
The product is CE marked and certified to ANSI/IEEE Std C12.20 (0.2% accuracy), ANSI/IEEE Std C62.41, and IEC 687 (0.2% accuracy). These certifications confirm measurement integrity, safety, and suitability for regulated environments, reducing risk during audits and system integration.
Long-term ROI is driven by accurate energy data, reduced wiring complexity, and seamless PXG integration via RS485. Regular checks focus on enclosure integrity, display readability, and communication health. The standardized 0.2% accuracy helps ensure consistent billing data and energy optimization without frequent recalibration.
