FAQs
Begin with de-energizing the panel and verifying voltage ratings. Mount the enclosure in a compliant location using the provided mounting footprint (24"H x 16"W x 8"D). Connect the 3‑phase, 4‑wire inputs to the meter input terminals, land the CTs as required, integrate the Modbus bus to your PLC/SCADA network, and verify continuity with the faceplate display. The fused disconnect and power-distribution features streamline wiring while maintaining protection.
The PXM350MA6521-4B carries CE marking and conforms to ANSI/IEEE Std C12.20 and IEC 687 with 0.2% accuracy. This combination supports regulatory compliance, precise energy measurement for billing, and reliable performance in electrical distribution environments, making it suitable for quality assurance, energy audits, and compliance reporting.
Yes, the unit includes Modbus communication for seamless integration with existing SCADA systems. Connect the Modbus RTU/ASCII channel to your PLC or historian, configure the register map for voltage, current, power, and energy, and enable data trending. This reduces manual data entry and accelerates energy analytics across plant operations.
The enclosure is rated NEMA 4X, designed for harsh and wet environments, with dimensions 24"H x 16"W x 8"D and an approximate weight of 100 lb. Plan for secure wall or panel mounting in clean, dry, or controlled outdoor locations where dust, water exposure, and corrosion protection are required, ensuring durable, long-term operation.
ROI comes from improved energy visibility, accurate billing, and reduced downtime due to faster fault detection. The device’s robust protection minimizes maintenance events, while Modbus integration enables continuous energy monitoring and trend analysis. Expect lower operating costs, better asset utilization, and informed insulation and maintenance planning over time.
