FAQs
Begin by verifying 120/240 VAC power availability and ensuring the 3-phase/4-wire configuration is routed correctly to the PXMP-MB-3B-A. Mount the unit in a suitable enclosure, connect the main fuse disconnect per local electrical codes, and terminate lines securely. Because the display is not included, plan for external monitoring or telemetry to read energy data. Follow the manufacturer’s installation sheet for wiring diagrams and protective earth connections to ensure safe operation in industrial environments.
The meter delivers ANSI/IEEE Std C12.20 accuracy at 0.2%, supports 120/240 VAC power supply, and uses a 3-phase/4-wire configuration with a main fuse disconnect. It is CE marked and complies with IEC 687 and ANSI/IEEE standards, ensuring regulatory alignment and reliable energy data for billing, energy audits, and utility reporting in industrial facilities.
Yes. The PXMP-MB-3B-A uses a NEMA 3R enclosure designed for outdoor and semi-exposed locations, providing protection against rain, dust, and incidental impact. This makes it suitable for outdoor substations, exterior control panels, and other industrial sites where weather-resistance and rugged metering are critical to maintaining accurate energy data without frequent maintenance.
The PXMP-MB-3B-A carries ANSI/IEEE Std C12.20 with 0.2% accuracy, ANSI/IEEE Std C62.41, IEC 687 with 0.2% accuracy, and CE Marking. These certifications validate measurement precision, transient protection performance, and compliance with international safety and environmental requirements, ensuring reliable operation, easier cross-border deployment, and acceptance in regulated facilities.
The ROI stems from improved energy visibility, reduced metering disputes, and lower maintenance due to a rugged enclosure and reliable measurement. With a compact 18 in x 33 in x 27 in footprint and a 100 lb weight, the unit minimizes space impact while delivering precise data for energy-management programs, watchdog monitoring, and remote telemetry integration, leading to faster payback in facilities with large electrical loads.
