The Square D LAL34225MC1021 is a 3-pole molded case circuit breaker from Schneider Electric's LAL Series, designed for thermal magnetic overcurrent protection in industrial power distribution systems. It is rated for 480V AC, 225A continuous current, and provides a 30kA interrupting capacity at 480V, with long time and instantaneous trip functions for coordinated fault clearing. This feed-thru connection breaker measures 4.44 inches wide by 3.09 inches deep, weighs 14.341 lb, and is constructed for panelboard mounting with a 24Vac shunt trip for remote tripping capability. It complies with applicable UL and NEMA standards for industrial electrical safety and reliability. Typical applications include main or feeder protection in commercial and industrial switchboards, motor control centers, and distribution panels.
