That 220 kA figure at 240 V means it can safely interrupt fault currents up to that level on a 240 V line — critical for high-fault-capacity panels where upstream coordination and SCCR headroom matter. At 415 V it still breaks 154 kA, and at 690 V it holds 17 kA, so it's sized for industrial distribution rather than light commercial. The 250 A rating holds flat from 40 °C up to 50 °C, then derates to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. If the panel ambient runs hot — say a packed enclosure near a furnace line — the 70 °C derated figure (223 A) is the one to size against, not the nameplate 250 A. Maximum power loss is 57 W, which factors into enclosure thermal calculations. Dimensions are 158 mm high, 105 mm wide, 70 mm deep.","metaTitle":"Siemens 3VA1225-6EF32-0KC0 SENTRON MCCB, 250 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1225-6EF32-0KC0 molded case circuit breaker, 3-pole, 250 A rated at 40 °C, 220 kA breaking capacity at 240 V.
