Eaton 3MM320R12 Residential Meter Stack - UL Listed

Multiple metering and a 200A rating provide independent measurement channels, reducing disputes over charges and streamlining utility management. This leads to faster invoicing, accurate energy accounting, and simplified tenant billing in multi-tenant residential or mixed-use developments. Five-jaw configuration and a 1200A bus rating allow flexible feeder routing and future expansion. This supports scalable distribution in outdoor enclosures and retrofit projects, ensuring the system can grow with building loads without replacing the meter stack. Sockets:3 with 3-ph in and 1-ph out enable per-phase monitoring and seamless interfacing with common utility service types. Application contexts include apartment buildings or campuses where energy data drives demand management and load balancing. No bypass design improves metering accuracy and tamper resistance, especially when paired with site-selected MCBs. This helps meet energy measurement standards and reduces risk of metering discrepancies in both residential and light commercial settings. Outdoor-rated, UL Listed construction supports reliable outdoor operation and code-compliant installation without extra weatherproof enclosures. This reduces total installed cost and accelerates commissioning in exposed locations. Utility approvals, including CenterPoint Energy TX acceptance, expedite permitting and interconnection, helping project teams meet AHJ timelines and streamline approval processes. Warranty protection provides a defined coverage period, giving installers and owners confidence in long-term performance and serviceability.
