Square D HDP36020 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 H-frame construction measuring 163 mm (H) x 112.78 mm (W) x 78.49 mm (D) and weighing 5 lb. The breaker employs a thermal-magnetic trip unit for both long-time and instantaneous protection, is rated for an interrupting capacity of 18kA at 480V, and operates within an ambient temperature range of -2 to 70 °C. Its bolt-on connection accommodates conductors from AWG 14 to 3/0, making it suitable for panelboards, switchboards, and industrial control panels requiring robust circuit protection.
