Square D HJA36150SA 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 150A current rating and a 600V AC voltage rating, housed within a compact H-frame measuring 163 mm x 104 mm x 86 mm (H x W x D) and weighing 6.001 lb. The breaker is constructed for robust performance, utilizing a thermal-magnetic trip unit with long-time and instantaneous (LI) protection functions and an I-Line style plug-in connection with lug terminals compatible with wire sizes from 14 AWG to 3/0 AWG. It complies with UL, CSA, NEMA, NOM, and IEC 60947-2 standards and is rated for an interrupting capacity of 65kA at 480V AC, with an operational temperature range of -25 to 70 °C. This unit is typically applied in industrial panelboards and switchboards and includes an integrated 120V AC shunt trip for remote tripping capability.
