Square D HLL36150M74 is a 3-pole molded case circuit breaker from the Powerpact family, designed to provide magnetic-only protection for industrial power systems. It is rated for 150A continuous current at 600VAC, with an interrupting capacity of 100kA at 480VAC, and features an instantaneous (I) trip function for short-circuit protection. The breaker has an H frame size, measures 6.4 in (163 mm) x 4.09 in (104 mm) x 3.4 in (86 mm), weighs 4.409 lb, and is constructed with a feed-thru connection and terminals accepting 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, and is certified for use in 3-phase systems within an operating temperature range of 28-158 °F (-2-70 °C). Typical applications include motor control centers, switchboards, and industrial distribution panels requiring high fault current withstand and selective coordination.
