Square D JJL36150 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial power distribution systems. It features a 150A current rating and a 600V AC voltage rating, housed within a compact J-frame measuring 191 mm H x 104 mm W x 86 mm D and weighing 4.81 lb. The breaker utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection, is constructed with lug terminals for feed-thru connection of 4 to 4/0 AWG copper or aluminum conductors, and operates within a temperature range of -2 to 70 °C. It complies with UL, CSA, NEMA, NOM, and IEC 60947-2 standards, making it suitable for three-phase applications in panelboards, switchboards, and industrial control panels where a 65kA interrupting rating at 480V is required.
