Breaking capacity hits 187 kA at 240 V and still holds 121 kA at 415 V, which means it handles high-fault scenarios common in industrial main feeders or large distribution panels without needing a current-limiting upstream device. Rated insulation voltage is 800 V, so it's comfortable on 480 V and 600 V class systems with margin. ## Thermal derating and power loss — the real-world numbers The breaker carries its full 250 A from 40 °C through 50 °C ambient. At 55 °C it derates to 241 A, at 60 °C to 232 A, at 65 °C to 222 A, and at 70 °C to 213 A. Maximum power loss is 48 W, which matters for enclosure heat-rise calculations when you're stacking multiple breakers in a single section. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Dimensions are 181 mm height, 140 mm width, 86 mm depth.","metaTitle":"Siemens 3VA2225-5HN42-0KC0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0KC0 molded case circuit breaker, 250 A rated, 4-pole, 187 kA at 240 V breaking capacity.
