Eaton ELFD3050L is a 3-pole molded case circuit breaker from the Series C family, designed for overcurrent and ground fault protection in industrial power distribution systems. It is rated for 480V AC, 50A continuous current, and delivers a 25kA interrupting capacity at 480V, with a thermal magnetic trip mechanism providing long-time and instantaneous protection alongside integrated ground fault sensing. This feed-thru connection breaker weighs 15 lb and is constructed for panelboard or switchboard mounting in three-phase applications. It complies with UL and NEMA standards for molded case circuit breakers. Typical applications include motor control centers, distribution panels, and industrial machinery requiring coordinated LIG protection.
