Eaton HKD3400T56WZGP is a 3-pole, 400A molded case circuit breaker from the Series C family, designed for primary overcurrent and ground fault protection in industrial power distribution systems. It operates at a maximum voltage rating of 600V and delivers a 65kA interrupting capacity at 480V, with a solid-state trip unit providing LSIG (Long-Time, Short-Time, Instantaneous and Ground Fault) protection functions. The unit features a K Frame size, bolt-on connection, and compact dimensions of 4.1 inches in depth, 5.5 inches in height, and 5.5 inches in width, weighing 3.5 lb. This breaker complies with industry standards for molded case circuit breakers and is suited for three-phase applications requiring precise, adjustable protection coordination. Typical industrial applications include motor control centers, switchboards, and panelboards in manufacturing plants, commercial facilities, and utility systems where high fault current capacity and selective coordination are critical.
