Square D BGA260204 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial electrical systems. It features a 20A current rating and a 600V AC voltage rating, housed within a compact G-frame measuring 137 mm x 54 mm x 89 mm (H x W x D) and weighing 3.09 lb. The breaker utilizes a thermal-magnetic trip mechanism for both long-time and instantaneous protection, is rated for 35kA interrupting capacity at 480V, and operates across a temperature range of -25 to 70 °C. It complies with major international standards including UL 489, IEC 60947-2, and CSA C22.2 No 5, and its I-Line style plug-in connection with lug terminals supports wire sizes from 14 AWG to 2/0 AWG for copper or aluminum conductors. This breaker is typically applied in commercial and industrial power distribution panels for branch circuit protection.
