Three-phase in, single-phase out metering with five jaws and two sockets simplifies the connection topology while reducing cabinet footprint and wiring points of failure, which translates to faster installs and lower labor costs. The 800 A bus rating on an aluminum bus delivers high current capacity with lighter weight and easier handling, improving long-term reliability in dense installations. Indoor/outdoor enclosure versatility enables installation in varied environments, reducing the need for separate enclosures and enabling consistent performance across locations. Compatibility with secondary circuit breakers BR2_, BRH2_, BRHH2_ provides flexible protection options, simplifying upgrades and maintenance while minimizing spare-part inventories. The included warranty—Eaton’s 25-000 policy, one year from installation or eighteen months from shipment—lowers lifecycle risk and supports predictable procurement budgeting. Utility approvals reflected in the specification set indicate broad compatibility with major utilities, reinforcing compliance confidence for commissioning teams. By design, bypass is None, which minimizes unnecessary failure points and supports straightforward fault isolation during service events. This solution is well-suited for commercial-residential transitions where centralized metering accelerates energy analytics and bill-back processes.
