Square D BJL36050 is a 3-pole molded case circuit breaker from the Powerpact family, designed for thermal-magnetic overcurrent protection in electrical distribution and industrial control panels. It is rated for 600V AC, 50A continuous current, and provides LI (Long-Time and Instantaneous) protection functions with a 65kA interrupting capacity at 480V AC. This standard breaker measures 5.4 in x 3.2 in x 3.1 in (H x W x D), weighs 2.93 lb, and features Everlink lug terminals on both ends for feed-thru connections, accepting wire sizes from 14 AWG to 3/0 AWG (copper/aluminum). It complies with UL 489, CSA C22.2 No 5, NEMA AB1, EN/IEC 60947-2, and other international standards, with certifications including UL, IEC, CCC, EAC, CSA, and NOM. Typical applications include branch circuit protection in switchboards, panelboards, and motor control centers within industrial and commercial facilities.
