FAQs
Installation begins with mounting the NEMA 12 enclosure in a suitable electrical space, ensuring the 480V service is properly fused and that the CT blocks are correctly connected per PXM. The device supports separate CT shorting blocks and a dedicated fuse control power disconnect, simplifying commissioning and maintenance while meeting CE and ANSI/IEEE standards. A field technician should verify wiring integrity, loop continuity, and ModbusRTU/BACnet MSTP configuration to guarantee accurate readings and safe operation.
The meter carries ANSI/IEEE Std C12.20 with 0.2% accuracy and IEC 687 with 0.2% accuracy, plus ANSI/IEEE Std C62.41 relevant testing. These certifications support precise energy measurement for billing and energy management, reducing discrepancies in utility settlements. CE Marking further confirms compliance for European operations, giving you confidence in global deployments and cross-border procurement.
Yes. The PXM350MA6521-2B5AWS is designed with accommodations for future expansion to 3-PXM350(MA6521) configurations, enabling additional meters in the same enclosure or system without a full redesign. This lowers incremental capital expenditure and minimizes downtime when scaling to meet growing load monitoring and energy accounting needs in industrial facilities.
The meter supports ModbusRTU and BACnet MSTP communication, enabling seamless data streaming to common EMS and SCADA platforms. This integration supports real-time energy monitoring, fault detection, and centralized reporting, helping engineers optimize energy use, improve maintenance planning, and align with corporate energy targets.
Long-term benefits include reduced field labor due to simpler commissioning, dependable 0.2% accuracy under ANSI/IEEE standards, and a rugged NEMA 12 enclosure that minimizes environmental risk. ROI is driven by improved energy visibility, accurate billing, and scalable capacity that avoids early equipment upgrades as load grows, translating to lower total cost of ownership over the product lifecycle.
