The Square D HLA360406 is a molded case circuit breaker from the Powerpact family, designed for thermal-magnetic protection in industrial power distribution systems. This three-pole, 40A unit operates at 600VAC with a high interrupting capacity of 100kA at 480VAC, utilizing LI (Long-Time and Instantaneous) trip functions for precise overcurrent protection. The H Frame breaker measures 6.4 in (163 mm) x 4.09 in (104 mm) x 3.4 in (86 mm) and weighs 3.999 lb, featuring an I-Line style plug-in connection and accepting wire sizes from AWG 14 to AWG 3/0 in aluminum or copper. 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, panelboards, and switchboards requiring reliable branch circuit protection in commercial and industrial environments.
