Eaton HFW3040L is a molded case circuit breaker from the Series C IEC family, designed for overcurrent protection in industrial power distribution systems. This three-pole, 40A unit is rated for 690V AC and provides LI (Long-Time and Instantaneous) protection functions through a thermal magnetic trip mechanism. The F Frame breaker measures 3.38 inches in depth by 6 inches in height by 4.13 inches in width, weighs 5 lb, and features a feed-thru connection configuration. It is IEC rated with an interrupting capacity of 70kA at 415V, suitable for three-phase applications. Typical uses include protecting branch circuits, feeders, and motor control centers in manufacturing plants, commercial buildings, and heavy industrial environments.
