Compatibility is designed around Eaton’s modular metering ecosystem. The meter stack works with compatible MCBs, and exact configuration depends on the selected MCB. Plan for four 125A sockets, the five-jaw arrangement, and the 9 o’clock fifth jaw if retrofitting or expanding a current service. Ensure the chosen MCBs match the service rating and feeder arrangement to achieve the intended metering scheme.
Key specs include four 125A sockets with a five-jaw design, outdoor UL Listed enclosure, 120/208 VAC operation, and the ability to accept three-phase input with single-phase output. The bus is rated at 800A, and the unit is intended for outdoor residential or light commercial metering deployments, with status dependent on the selected MCB configuration.
Yes. The Eaton 3MM412R2RLBACBC is specifically designed for outdoor service entrances, featuring a weather‑resistant enclosure and UL Listed certification. Its multi-meter capability supports scalable residential metering while providing safety and compliance in outdoor conditions, making it a reliable choice for outdoor installations.
The catalog notes indicate a fifth jaw is included at the 9 o’clock position. This feature enhances mounting flexibility, allows additional conductor routing, and supports expansion or reconfiguration without reworking the primary metering framework. It is particularly beneficial for future capacity changes and modular upgrades.
Warranty terms follow Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This provides a clear safety net for early reliability issues, while Eaton’s support ecosystem helps with commissioning, spare parts, and field service planning for long-term asset reliability.
