Siemens BQ3B02000S01 is a 3-pole molded case circuit breaker from the BQ Series, designed for thermal-magnetic protection in Siemens panelboards. This unit is rated for 240V AC, 20A, and 10kA interrupting capacity at 240V, with a 120V non-interchangeable shunt trip for remote tripping. The breaker measures 5.906 x 3.937 x 3.937 inches, weighs 1.565 lb, and features a bolt-on connection with lug terminals accepting 8 AWG to 4 AWG (Al) or 6 AWG (Cu) wire. It is UL Listed, CSA certified, and HACR rated, with an operating temperature range of -13°F to 158°F (-25°C to 70°C). Typical applications include industrial and commercial power distribution requiring reliable overcurrent and short-circuit protection.
