Square D HDL36050 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial power distribution systems. It features a 50A current rating and a 600V voltage rating, housed within a compact 150A/HD frame measuring 163 mm H x 104 mm W x 86 mm D and weighing 4.05 lb. The breaker utilizes a thermal-magnetic trip unit for combined long-time and instantaneous (LI) protection and is certified to UL, CSA, NOM, and IEC 60947-2 standards. Its three-pole, bolt-on configuration with line/load lugs for AWG 14 to 3/0 wire makes it suitable for three-phase applications in panelboards and switchboards, offering an interrupting capacity of 18kA at 480V AC and an operational temperature range of -25 to 70 °C.
