FAQs
The PXM350MA6321-2B4A is designed for straightforward panel installation inside a NEMA 12 enclosure. Ensure a 480V supply and 50/60 Hz operation, mount the unit to align with the enclosure dimensions (30inH x 20inW x 8inD), connect the four meters via the CT shorting block as specified, and wire the ModbusRTU or BACnet MSTP network according to the controller’s guidance. The unit ships with main fuse and control power fuse disconnects per PXM, simplifying safe power isolation during commissioning. This approach minimizes field rewiring and accelerates time-to-value for energy monitoring projects.
This enclosed meter adheres to ANSI/IEEE Std C12.20 with 0.2% accuracy, delivering billing-grade energy measurements. It supports 480V nominal, 480VAC power input, and a 50/60 Hz frequency range. With four meters in a single enclosure and a meter faceplate display, operators gain precise real-time energy data across multiple feeders, enabling accurate cost allocation and performance benchmarking for industrial facilities.
Yes. The PXM350MA6321-2B4A is well-suited for manufacturing lines and data centers that require centralized energy monitoring, robust enclosure protection, and reliable data communication. Its NEMA 12 enclosure, four simultaneous meters, and ModbusRTU/BACnet MSTP connectivity support scalable energy management, fast fault detection, and integration with building management systems, reducing energy waste and improving asset utilization.
The enclosure carries CE Marked compliance, plus ANSI/IEEE C12.20 (0.2% accuracy) and IEC 687 performance qualifications, with C62.41 surge considerations. These certifications ensure compliance for European and North American markets, support accurate metering for billing, and align with utility interoperability requirements, reducing risk during audits and operational approvals for energy management initiatives.
The four-meter in one enclosure reduces hardware footprint and simplifies calibration routines, lowering maintenance labor and spare-part needs. Its reliable energy data supports targeted energy optimization, enabling accurate consumption tracking, reduced demand charges, and informed capex planning for facility upgrades. Integrated ModbusRTU/BACnet MSTP connectivity accelerates data-driven decision-making across operations, driving measurable ROI over equipment lifecycles.
