The Square D HJL36100M73SK is a 3-pole molded case circuit breaker from the Powerpact family, designed for magnetic-only protection in industrial applications. It is rated for 100A at 600VAC with a 65kA interrupting capacity at 480V, and features an instantaneous (I) trip function for short-circuit protection. This H-frame breaker measures 6.4 in x 4.09 in x 3.4 in (163 mm x 104 mm x 86 mm) and weighs 5 lb, with feed-thru connections and a wire size range of AWG 14 to AWG 3/0 for aluminum or copper terminals. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, with an operating temperature range of 28 to 158 °F (-2 to 70 °C). Typical applications include motor control centers, panelboards, and switchboards requiring reliable overcurrent protection in three-phase systems.
