The Square D LAL363001021 is a 3-pole molded case circuit breaker from Schneider Electric's LAL Series, designed for thermal magnetic protection with LI (Long-Time and Instantaneous) trip functions. It is rated for 600V AC, 300A continuous current, and 30kA interrupting capacity at 480V, operating on a 3-phase system with a bolt-on connection. This L Frame breaker measures 11 inches in height, 6 inches in width, and 5.84 inches in depth, weighing 16.8 lb, and features lug terminals for wiring. It complies with CSA, UL Listed, and IEC standards, and is certified accordingly, making it suitable for industrial applications requiring reliable overcurrent protection. Typical uses include power distribution panels and switchboards in manufacturing, commercial, and utility environments, with an integrated 120/240Vac shunt trip for remote tripping capability.
