Square D FA34050G is a molded case circuit breaker designed for overcurrent and short-circuit protection in industrial power distribution systems. This three-pole, 50A unit operates at 480V with an 18kA interrupting capacity and utilizes thermal-magnetic protection with LI (Long-Time and Instantaneous) trip functions. The breaker features an I-Line style plug-in connection, weighs 12 lb, and is constructed for panelboard mounting within the Square D I-Line family. It complies with applicable UL and NEMA standards for molded case circuit breakers. Typical applications include branch circuit protection in commercial and industrial electrical panels, motor control centers, and switchboards requiring ground fault shunt trip wiring protection.
