Eaton Specification Sheet - PXM350MA6321-3A1A
Integrated display and a single meter enclosure streamline field wiring, consolidate measurements, and reduce cabinet space. This consolidation drives faster commissioning, easier maintenance, and lower installation costs on every project. Modbus RTU communication enables seamless integration with SCADA, energy management systems, and remote monitoring, delivering time-stamped energy data for real-time decision making. The TOU capability supports demand management without external controllers, reducing peak charges and improving utility compliance. Flexible input options cover 120-240 V L-L with 120/240 Vac power, plus 100-415 Vac L-N and 100-300 Vdc PS, enabling retrofit installations without reconfiguring plant wiring. A 333 mV current input and pulse output deliver high-precision energy capture suitable for utility-grade metering, load profiling, and energy accounting. Designed in a NEMA 3R enclosure with CE marking and ANSI/IEEE 0.2% accuracy, the meter is suited to outdoor or harsh environments while meeting global standards. The 14 in high by 8 in wide by 8 in deep footprint and 100 lb weight support straightforward installation and service within standard electrical rooms. One built-in relay output provides simple local control for load shedding, sequencing, or alarms, enhancing TOU strategies and minimizing external hardware requirements. Together with an integral faceplate display and 50/60 Hz compatibility, the meter delivers readable, real-time data across global sites. Field technicians benefit from a ready-to-install solution that reduces wiring complexity, speeds commissioning, and lowers maintenance costs, while facilities teams gain reliable, actionable energy insights for continuous improvement.
