Siemens HGB3B045B is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase electrical systems. It features a 45A current rating and a 600V AC voltage rating, housed within a compact, robust enclosure measuring 2.961" x 2.87" x 4.1005" and weighing 2.756 lb. The breaker complies with UL, CSA, IEC, and NOM standards and is engineered for demanding industrial applications such as panelboards, switchboards, and motor control centers, operating effectively in temperatures from -25°C to 70°C. Its thermal-magnetic protection mechanism combines long-time and instantaneous (LI) trip functions to safeguard circuits against both overloads and high-fault currents.
