Square D HJL36045 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 45A current rating and a 600V voltage rating, housed within a compact H-frame measuring 163 mm x 104 mm x 86 mm (HxWxD) and weighing 4.145 lb. The breaker utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection, offers a 65kA interrupting capacity at 480V, and is compliant with UL, CSA, NEMA, and IEC 60947-2 standards. Its feed-thru lug connection accommodates copper or aluminum conductors from 14 AWG to 3/0 AWG, making it suitable for a wide range of industrial panelboards and switchboards operating in ambient temperatures from -25°C to 70°C.
