Eaton UTH7339UCH Meter Socket - UL Listed
Part Number: UTH7339UCH
Quick Summary
Eaton UTH7339UCH meter socket is a high-capacity, commercial meter connection designed for reliable service entrances. This unit addresses the common industry pain point of combining safe, heavy-conductor terminations with straightforward installation in tight equipment rooms. UL Listed ensures compliance with recognized safety standards, and the 600 V/320 A rating supports demanding commercial metering needs. The product’s six key attributes—top/bottom feed, seven-jaw design, ringless hub cover plate, lever bypass, and three-wire configuration—work together to reduce field adjustments and downtime. By aligning with Eaton metering ecosystems, it supports scalable energy management strategies while delivering predictable electrical performance across multiple sites. For procurement and engineering teams, this means faster project turnover, consistent installation practices, and improved total cost of ownership over the asset lifecycle.

Eaton Specification Sheet - UTH7339UCH
Feature → Business Impact → Application: The UTH7339UCH provides a 320A amperage rating and 600V voltage rating, enabling reliable service connections for large commercial loads and utility-grade metering installations. This combination reduces the number of required equipment stages, lowering footprint and installation time while improving safety margins for high-current applications in commercial buildings. Application-wise, it suits meter-socket installations in data centers, retail complexes, and multi-tenant facilities where uninterrupted power and precise metering are critical. Feature → Business Impact → Application: Top/bottom feed and seven-jaw design improve wire management and connection integrity, yielding lower resistance, fewer hot spots, and reduced maintenance calls. In practice, installers experience cleaner terminations with #600 kcmil conductors, facilitating quicker commissioning and fewer re-terminations in retrofit projects. Feature → Business Impact → Application: Ringless hub cover plate and large hub configuration simplify mounting in tight spaces, support faster inspections, and help meet code-based enclosure requirements, especially in retrofit upgrades. This translates to safer service disconnect workflows and reduced exposure for technicians. Feature → Business Impact → Application: Lever bypass and ground connection support three-wire, single-phase systems, delivering straightforward field servicing and robust ground continuity in commercial metering setups. This minimizes service disruption during maintenance windows and supports compliance with grounding practices. Feature → Business Impact → Application: UL Listed certification and Eaton compatibility guarantee ongoing compliance with NEC requirements and interoperability with Eaton’s broader metering and distribution product family, enabling scalable upgrades across portfolios while controlling procurement complexity. These characteristics are particularly valuable for engineers pursuing standardized specifications across campuses, hospitals, and office complexes, where consistent equipment behavior reduces risk and drives predictable ROI.
