Square D HDL36070 is a three-pole molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial power distribution systems. It features a 70A current rating and a 600V AC voltage rating, housed within a compact 150A/HD frame measuring 163 mm H x 104 mm W x 86 mm D and weighing 4.12 lb. The breaker utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection and is constructed for feed-thru connection with line/load lugs compatible with copper or aluminum wire from 14 AWG to 3/0 AWG. It complies with UL, CSA, NEMA, NOM, and IEC 60947-2 standards and is rated for an interrupting capacity of 18kA at 480V AC, making it suitable for a wide range of commercial and industrial panelboards and switchboards operating in ambient temperatures from -25°C to 70°C.
