Eaton HKDDC3400F is a molded case circuit breaker frame from the Series C family, designed for overcurrent protection in industrial power distribution systems. It is rated for 600V AC, 400A, and 42kA interrupting capacity at 600V, with a 3-pole, 3-phase configuration and thermal magnetic protection providing LI (Long Time and Instantaneous) trip functions. The unit measures 4.1 inches in depth, 5.5 inches in height, and 5.5 inches in width, weighs 9.7 lb, and features a bolt-on connection with an operating temperature range of -13 to 158 °F (-25 to 70 °C). It is UL certified and manufactured in the Dominican Republic. This item is a frame only, meaning it does not include lugs or a trip unit, and is intended for use in switchboards, panelboards, and motor control centers requiring high fault current withstand.
