The Square D HJL36050M72BC is a molded case circuit breaker from the Powerpact family, designed to provide magnetic-only protection for industrial power distribution systems. This 3-pole, 50A breaker operates at 600VAC and delivers a 65kA interrupting capacity at 480V, with instantaneous (I) trip functionality for short-circuit protection. The unit measures 6.4 in (163 mm) x 4.09 in (104 mm) x 3.4 in (86 mm) and weighs 5 lb, featuring a feed-thru connection that accepts AWG 14 to AWG 3/0 aluminum or copper wire. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, with an operating temperature range of 28-158 °F (-2-70 °C). Typical applications include motor control centers, switchboards, and industrial panelboards requiring high-fault-current protection in three-phase systems.
