The Square D HLL36050M72 is a 3-pole molded case circuit breaker from the Powerpact family, designed to provide magnetic-only protection for industrial power distribution systems. It is rated for 50A at 600V AC, with a high interrupting capacity of 100kA at 480V, and features LI (Long-Time and Instantaneous) trip functions within an H Frame. This unit measures 6.4 in (163 mm) x 4.09 in (104 mm) x 3.4 in (86 mm), weighs 4.376 lb, and uses a feed-thru connection with wire sizes from AWG 14 to AWG 3/0 (aluminum/copper). It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, and is certified for use in three-phase systems within a temperature range of -13°F to 158°F (-25°C to 70°C). Typical applications include motor control centers, switchboards, and industrial panelboards requiring robust overcurrent protection.
