The Square D LHL26300V is a molded case circuit breaker from the LHL Series, designed to provide overcurrent protection through its thermal magnetic trip mechanism. This 2-pole, 1-phase unit is rated for 300A at 600VAC, with an interrupting capacity of 35kA at 480VAC, and features LI (Long-Time and Instantaneous) protection functions. Housed in an L Frame, the breaker measures 11 inches in height, 6 inches in width, and 5.84 inches in depth, weighing 18 lb, with a feed-thru connection configuration. It is built to comply with industry standards for industrial electrical distribution systems. Typical applications include protecting feeders and branch circuits in commercial and industrial power panels, switchboards, and motor control centers.
