FAQs
This enclosed meter fits standard 24x16x8 inch spaces and weighs about 100 lb, designed for easy mounting in 3PH/4W panels. It includes a CT shorting block and a fused control power disconnect to simplify wiring. Ensure proper clearances for ventilation and access to the faceplate, and connect the Modbus interface to your PLC/SCADA network for data integration.
The 0.2% accuracy rating, certified under ANSI/IEEE Std C12.20 and IEC 687, minimizes metering error in energy usage readings. This improves billing accuracy, supports precise energy management, and reduces variance in utility reporting, making it easier to demonstrate savings and compliance across facilities and projects.
Yes. The PXM350MA6521-2A provides Modbus communication to connect with PLCs and SCADA platforms. It enables real-time energy data streaming, facilitates alarms and trending, and integrates with Eaton’s enclosed meter family for scalable metering across multiple panels without reinventing the data backbone.
The meter is CE marked and carries ANSI/IEEE Std C12.20 (0.2% accuracy) and IEC 687 (0.2% accuracy) certifications, along with ANSI/IEEE Std C62.41. It is housed in a NEMA 12 enclosure, suitable for indoor industrial environments, and supports 50/60 Hz operation for broad compatibility and regulatory compliance.
By consolidating metering, CT shorting, and a fused disconnect in a single enclosure, the PXM350MA6521-2A reduces installation time, wiring errors, and field maintenance visits. The Modbus interface enables proactive energy analytics, aiding demand management and potentially lowering utility costs and downtime through improved visibility and faster fault detection.
