Its interrupting capacity reaches 187 kA at 240 V and 121 kA at 415 V, which means it can safely clear high-fault currents in industrial distribution panels without upstream coordination issues. ## Interrupting and thermal performance At 240 V the breaker interrupts 187 kA; at 415 V and 440 V it holds 121 kA, dropping to 79 kA at 500 V and 5.1 kA at 690 V. That 187 kA figure at 240 V gives headroom for high-capacity transformer secondaries or large motor branch circuits where fault current can exceed 100 kA. The thermal derating curve is flat from 40 °C to 50 °C at 250 A, then steps down to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C — so in a warm panel (say 55 °C ambient) you lose only 9 A, but at 70 °C you're down to 213 A, which matters if the load is near the nameplate. The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. The width of 105 mm is standard for a 3-pole MCCB in this frame size; it will fit existing SENTRON 3VA mounting footprints without panel rework if the previous breaker was the same frame.","metaTitle":"Siemens 3VA2225-5HN32-0AE0 SENTRON MCCB, 250 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-5HN32-0AE0 molded case circuit breaker, 250 A rated, 187 kA interrupting at 240 V.
