It carries a continuous current of 250 A at 40 °C, derating to 223 A at 70 °C — useful when the breaker lives in a warm panel or next to other heat sources. Interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V, so it handles high-fault utility feeds or transformer-secondaries without cascading upstream. Dimensions are 158 mm high, 105 mm wide, 70 mm deep, fitting standard SENTRON panel cutouts. Its 105 mm width occupies three standard 35 mm module spaces.","metaTitle":"Siemens SENTRON 3VA1225-5EF32-0AB0 MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1225-5EF32-0AB0 molded case circuit breaker, 250 A rated, 3-pole, 187 kA interrupting at 240 V.
