Siemens B225 is a 2-pole, bolt-on circuit breaker designed for providing reliable overcurrent protection in single-phase industrial and commercial electrical systems. It features a 25A current rating and a 600V AC voltage rating, housed within a compact 125A/BL frame with dimensions of 100 x 70 x 50 mm (3.937 x 2.756 x 1.969 inches). This thermal-magnetic breaker, offering Long-Time and Instantaneous (LI) trip functions and a 10kA interrupting rating at 240V, is constructed for operation in temperatures from -25 to 70 °C and complies with CSA, HACR, and UL standards. It is specifically engineered for integration into Siemens P1 panelboards to protect branch circuits, supporting wire sizes from 12 AWG aluminum or 14 AWG copper up to a maximum of 10 AWG via its lug terminals.
