The Square D BDA24030Y1 is a 2-pole molded case circuit breaker from the PowerPact B family, designed to provide thermal-magnetic protection for electrical distribution equipment and industrial control panels. It is rated for 30A at 480VAC with an AIC rating of 18kA@480VAC, utilizing a 125A/BD frame size and offering long-time and instantaneous trip functions for reliable overcurrent protection. This standard breaker measures 5.4 in (137 mm) x 2.1 in (54 mm) x 3.5 in (89 mm) (H x W x D), weighs 3.13 lb, and features an I-Line connection on the load end with aluminum mechanical lugs on the line end, accepting wire sizes from 14 AWG to 2/0 AWG (aluminum/copper). It complies with multiple international standards including UL 489, CSA C22.2 No 5, NEMA AB1, EN/IEC 60947-2, and GB 14048.2, with certifications from UL, IEC, CCC, EAC, CSA, and NOM. Typical applications include branch circuit protection in switchboards, panelboards, and industrial control panels operating in ambient temperatures from -25°C to 70°C.
