Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V — numbers that tell you it'll clear a hard fault without the arc climbing upstream. That alarm switch closes when the breaker trips, giving you a positive signal for a PLC or annunciator — handy for fault isolation out here in the grease. The breaker measures 181 mm high, 105 mm wide, and 86 mm deep. That 105 mm width is the standard 3-pole MCCB footprint for this class — it'll drop into a panel that was laid out for a SENTRON 3VA frame without re-drilling the gland plate. ## Thermal derating you need to know The breaker is rated 250 A from 40 °C up to 50 °C. At 55 °C it derates to 241 A, at 60 °C to 232 A, and at 70 °C to 213 A. The maximum operating temperature is 70 °C; storage can go from -40 °C to 80 °C.","metaTitle":"Siemens 3VA2225-6HN32-0DH0 SENTRON MCCB, 250 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-6HN32-0DH0 molded case circuit breaker, 3-pole, 250 A, ETU350 trip unit, 242 kA at 240 V.
