FAQs
When installing the 35MM320R12 in commercial panels, verify panel rating and space for a 3R enclosure, ensure proper clearance for the 52.63 inch height, and follow torque specifications for the 5-jaw sockets. Use the 120/240Vac rating to plan conductor sizing and protective devices, and confirm compatibility with 3-phase in / 1-phase out configurations to avoid miswiring. The result is safer commissioning, faster fault isolation, and smoother maintenance.
Yes. The 35MM320R12 is designed for 3R meter stacks with 3-phase in and 1-phase out configurations, enabling precise metering of multi-branch circuits. This compatibility supports accurate load balancing and simplifies feeder monitoring in commercial and light industrial installations, reducing custom wiring needs and lowering project risk.
The model carries UL Listed certification, which verifies safety and performance for electrical equipment in commercial environments. While UL Listed is the primary certification available for this product, Eaton’s metering stack designs are aligned with widespread utility approvals to support interconnection and regional compliance across major utility territories.
A plug-in socket design minimizes on-site wiring changes and simplifies component replacement, reducing maintenance downtime and labor costs. The 35MM320R12’s durable construction and UL safety certification contribute to longer service life and fewer unscheduled outages, delivering lower total cost of ownership for commercial power distribution projects.
The unit is designed to align with a broad list of utility approvals, including major systems under Indiana Michigan Power, AEP East, and other regional providers. This enables smoother interconnection processes and reduces acceptance testing time when deploying meter stacks across multiple states and utility territories.
