Square D HDL36020 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 20A current rating and a 600V AC voltage rating, housed within a compact 150A/HD frame with dimensions of 163 mm H x 104 mm W x 86 mm D and a weight of 4.061 lb. The breaker utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection, is constructed with bolt-on connections and line/load lugs compatible with wire sizes from 14 AWG to 3/0 AWG, and operates within a temperature range of -25 to 70 °C. It complies with UL, CSA, NEMA, NOM, and IEC 60947-2 standards, making it suitable for panelboards, switchboards, and industrial control panels where an 18kA interrupting rating at 480V is required.
