Eaton Specification Sheet - 35MM240R1240C
Plug-in socket design streamlines installation and service, reducing field wiring time and potential connection errors. This enables quick meter swaps or upgrades without electrical shutdowns, which is critical in retrofit projects and busy facilities. NEMA 3R rating and rainproof-cap options provide outdoor readiness, delivering weather resistance that protects metering equipment in parking structures, exterior panels, and outdoor enclosures. Exit options at the top, bottom, or back and a K-frame included with five-jaw sockets support flexible routing, robust connections, and simplified mounting for three-phase in, single-phase out configurations (A-B) with 120/240 VAC and 208Y/120V metering. Compatibility with Eaton MCBs and a clear warranty path reduce risk and maintenance costs, while the compact footprint and 400A socket rating enable scalable metering for growing facilities. Overall, this meter stack aligns with modernization projects, retrofit programs, and data-center readiness by delivering reliable, compliant, and easy-to-service metering infrastructure.
