Square D HDL36090SA 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 90A current rating and a 600V voltage rating, housed within a compact H-frame measuring 163 mm H x 104 mm W x 86 mm D and weighing 5 lb. This thermal-magnetic breaker offers LI (Long-time and Instantaneous) protection functions, is compliant with UL, CSA, NEMA, and IEC 60947-2 standards, and includes a 110/130Vac shunt trip. It is typically applied in panelboards and switchboards for feeder and branch circuit protection, supporting wire sizes from AWG 14 to 3/0.
