Square D QOB2901021 is a 90A molded case circuit breaker from the QOB series, designed to provide thermal-magnetic protection against overloads and short circuits in electrical distribution systems. It operates at 120/240VAC with a 10kA interrupting capacity at 120V, features a 2-pole bolt-on connection, and supports wire sizes from AWG 4 to AWG 2/0 for copper or aluminum conductors. The breaker measures 3.5 in (89 mm) in height, 2.2 in (57 mm) in width, and 2.9 in (74 mm) in depth, weighs 1 lb, and uses a pressure plate terminal connection with long-time and instantaneous trip functions. It is UL Listed and CSA certified, suitable for single-phase applications within a temperature range of -13°F to 158°F (-25°C to 70°C). This breaker is typically used in industrial and commercial panelboards for branch circuit protection.
