Plug-in socket
The plug-in socket design with two integrated 350A breakers simplifies field wiring and accelerates commissioning, reducing commissioning labor and the risk of mis-wiring in commercial installations. This directly improves project timelines and safety compliance while maintaining reliable metering accuracy. The hardware accommodates 120/240V single-phase and 208Y/120V networks, delivering flexible metering for multi-tenant facilities and retrofit projects without the need for multiple ad-hoc meters. With a NEMA 3R enclosure and UL Listed certification, it is well suited for outdoor or rain-prone environments, reducing weather-related maintenance and extending service life. The main feeders can exit top, bottom, or back, providing installation versatility in crowded electrical spaces and simplifying retrofits in existing panels. Two sockets and a pair of five-jaw fittings enable scalable metering for evolving loads while keeping wiring clean and accessible. The 400A service rating supports high-demand applications common in commercial buildings, large offices, and light industrial facilities, ensuring accurate measurement without sacrificing space or safety. The stack integrates smoothly with Eaton’s monitoring and protection solutions, aligning procurement with existing maintenance contracts and simplifying spare parts management for long-term reliability.
