Siemens BQ3B04000S01 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase electrical systems. It features a 40A current rating and a 240V voltage rating, housed within a compact 125A frame with dimensions of 5.906 x 3.937 x 3.937 inches and a weight of 1.698 lb. The breaker is constructed with a thermal-magnetic trip unit for long-time and instantaneous protection, utilizing a bolt-on connection with lug terminals suitable for copper (AWG 8 to 6) or aluminum (AWG 8 to 4) conductors. It complies with UL, CSA, and HACR standards and is rated for an interrupting capacity of 10kA at 240V, operating reliably in ambient temperatures from -25°C to 70°C. This shunt trip breaker is typically applied in Siemens panelboards for industrial and commercial power distribution, where its integrated 120V shunt trip coil provides a means for remote circuit opening.
