Eaton PXQ-ST2-1A1-2A-A Enclosed Meter - NEMA12
Part Number: PXQ-ST2-1A1-2A-A
Quick Summary
Eaton enclosed meter delivers integrated panel metering for commercial and light-industrial electrical distributions. Installers often struggle with space constraints, wiring complexity, and reliable data capture in compact enclosures. With a NEMA 12 enclosure, 120–240 V power supply, and a three-phase/four-wire configuration, this meter offers robust protection and accurate measurement. By combining a dedicated CT shorting block, a main fuse disconnect, and a built-in display, it accelerates commissioning and reduces wiring errors. The result is faster project timelines, improved data visibility for energy management, and easier integration with monitoring software, helping facilities optimize energy use and drive lower total cost of ownership.

FAQs
The PXQ-ST2-1A1-2A-A is designed for 3-phase, 4-wire electrical configurations and includes a main fuse disconnect plus a CT shorting block to ensure safe, accurate metering. It operates on a 120–240V supply and supports standard 50/60 Hz systems, making it a solid choice for most commercial and light-industrial panels. Installation workflows benefit from integrated components that reduce wiring complexity and save time during commissioning.
This model uses a NEMA 12 enclosure rated for indoor use, providing dust and moisture protection. Its overall footprint is 24 inches wide, 20 inches deep, and 12 inches high, with an approximate weight of 100 pounds. It is designed for panel mounting in distribution cabinets, machine rooms, or service enclosures, enabling straightforward integration into existing infrastructure.
The enclosure ships with a CT shorting block and a DC power supply integrated into the unit, along with a built-in display for local metering reads. This configuration minimizes external wiring, simplifies start-up, and accelerates data collection. When planning, consider available space for the 24x20x12 inch footprint and ensure panel cutouts accommodate the mounting depth.
The meter is housed in a NEMA 12 enclosure, offering indoor protection against dust and water exposure typical in many facility environments. It supports 50/60 Hz operation and 120–240V power, aligning with common electrical distribution practices. For regulatory compliance, confirm site-specific safety requirements and any necessary local documentation as part of the procurement process.
The PXQ-ST2-1A1-2A-A offers faster commissioning due to an integrated CT shorting block, main fuse disconnect, and built-in display, reducing field wiring time and commissioning labor. Improved data visibility supports energy management initiatives and enables proactive maintenance decisions. Over time, this translates to lower outage risk, better energy analytics, and a lower total cost of ownership compared with field-assembled metering solutions.
