Interrupting capacity drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That 17 kA at 690 V suits it for 690 V industrial networks common in mining and heavy manufacturing — verify your system's prospective fault current against that figure. Rated 250 A from 40 °C through 50 °C ambient, then derates linearly to 223 A at 70 °C — the operating limit. Panel footprint: 140 mm wide, 158 mm tall, 70 mm deep — standard for this frame size in the SENTRON 3VA family.","metaTitle":"Siemens 3VA1225-5GF42-0AD0 SENTRON MCCB, 250A, 4-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1225-5GF42-0AD0 molded case circuit breaker. 250 A rated, 4-pole, 187 kA at 240 V.
