The Square D HJP36050 is a 3-pole, 50A molded case circuit breaker from the Powerpact family, designed to provide thermal-magnetic protection for electrical systems. It is rated for 600V AC and 50A continuous current, with a high interrupting capacity of 65kA at 480V AC. This bolt-on breaker measures 6.4 in (163 mm) x 4.09 in (104 mm) x 3.4 in (86 mm) (H x W x D) and weighs 4.9 lb, featuring lug and terminal nut connections for wire sizes from 14 AWG to 3/0 AWG (Cu/Al). It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, and is certified by UL, CSA, and NOM. Typical industrial applications include motor control centers, panelboards, and switchboards requiring reliable overcurrent and short-circuit protection in three-phase systems.
