FAQs
Installation involves mounting the NEMA 12 enclosure in a suitable indoor cabinet space, connecting the 120-240 VAC power supply as specified, and wiring the single meter to your main service or distribution panel. Ensure adequate clearance for service access, follow local electrical codes, and secure the unit with recommended mounting hardware to minimize vibration and impact during operation.
This meter is CE marked and carries ANSI/IEEE Std C12.20 (0.2% accuracy), ANSI/IEEE Std C62.41, and IEC 687 certifications. These standards support accuracy in energy measurement, surge considerations, and environmental endurance, helping you meet regulatory and utility reporting requirements across multiple regions.
Yes. The PXM350MA6321-2A1A is designed for 3-phase, 4-wire configurations with a 120-240 VAC power supply and a main fused disconnect, making it ideal for industrial power metering, energy monitoring, and utility-grade measurement in mechanical rooms and distribution panels.
The enclosure is NEMA 12 rated with dimensions 24 inches high by 16 inches wide by 8 inches deep, and it weighs approximately 100 pounds. The unit supports a single meter faceplate display, and its size fits standard electrical spaces used in many retrofits and new builds.
The enclosed design shields the meter from contaminants, reducing maintenance cycles. Accurate 0.2% metering combined with CE and ANSI/IEEE certifications enhances billing accuracy and regulatory compliance, lowering audit risk and supporting energy-management initiatives. The built-in disconnect also simplifies installation and service, contributing to faster project timelines and lower labor costs.
