Eaton commercial meter stack 37MM240R124024 - UL Listed

High amperage with two sockets is a core feature, enabling up to 400A service in a single stack. This reduces equipment diversity on site and minimizes spare-part inventories, delivering greater project predictability and shorter lead times. In practice, operators can specify one unit to serve multiple tenants or critical loads, simplifying procurement and commissioning for office complexes and light industrial facilities. Pre-installed internal breakers—one 250A and one 400A—and a dedicated 400A socket streamline wiring and testing during the build phase. The business impact is a shorter installation window, lower labor costs, and fewer field modifications that can cause delays. This configuration is well-suited for 3-phase commercial feeders, retail storefronts, data centers, and other multi-load applications where space is constrained. Ringless cover reduces physical damage risk during handling and simplifies inspection access. The lever bypass provides safe service isolation without full disconnection, supporting safer maintenance windows. With seven jaws and two sockets, the unit accommodates flexible conductor routing and reduces rework in complex bus configurations. Aluminum 1200A bus delivers a robust current path with low impedance, improving overall voltage regulation under heavy load. The result is lower voltage drop, better power quality, and enhanced protection coordination for downstream equipment. This bus design supports scalable upgrades as facility loads grow. Factory A-B phase balance helps ensure even loading across three phases, reducing neutral currents and motor heat. The measured balance translates to longer equipment life and fewer nuisance trips during peak demand. When paired with 208Y/120V service and precise metering, it supports reliable energy management for commercial operations.
