The Eaton EHD frame is a molded-case circuit breaker (MCCB) rated at 45A, 3-Pole, 480V — designed for industrial panelboards and switchboards, not residential loadcentres. It is suitable for Eaton/Cutler-Hammer EHD-compatible panelboards and motor-control applications where a compact MCCB with a higher interrupting rating is required.
Send us your panelboard model and we'll confirm fit and compatibility.
