Siemens B245H00S01 is a 2-pole, 45A molded case circuit breaker from the BL Series, designed for thermal magnetic overcurrent protection with an integrated 120V shunt trip for remote disconnection. It is rated for 120/240V AC, single-phase systems, with an AIC rating of 22kA at 240V, and accepts wire sizes from 14 AWG (Cu) to 6 AWG (Al/Cu) via lug terminals. This bolt-on breaker measures 3 in x 2 in x 2 in, weighs 0.705 lb, and is constructed for use in Siemens P1 panelboards, offering long time and instantaneous trip functions within a 125A/BLH frame. It is CSA Certified, HACR Rated, NOM Certified, and UL Listed, with an operating temperature range of -13°F to 158°F (-25°C to 70°C). Typical industrial applications include branch circuit protection in commercial and light industrial power distribution systems requiring remote trip capability.
