Siemens BL B235 Circuit Breaker

Siemens B235 is a two-pole bolt-on molded-case circuit breaker in the BL family. It is rated 35 A and designed for 120/240 V AC operation, intended for panelboard mounting in Siemens panels or other compatible enclosures. The device provides Thermal-Magnetic trip protection with an interrupt rating of 10 kA at 240 V, making it suitable for branch circuits carrying moderate loads while offering reliable short-circuit protection. As a BL-type bolt-on breaker, it is a non-interchangeable trip device used for panelboards with bolt-on footprints and common-trip functionality across both poles. It is UL-listed for use with 60/75 °C conductors up to 40 A within the BL family, aligning with standard residential and light commercial distribution needs. Typical applications include protection for lighting circuits, receptacle circuits, and small equipment feeds in a home or small business electrical distribution system, or as a replacement in compatible Siemens panelboards. The B235 designation specifically identifies this model as 35 A, 2-pole, 120/240 V AC, 10,000 AIC, ensuring correct rating when selecting a replacement or additional breakers in a BL-series panel.
