Those numbers mean it handles high-fault-current scenarios typical of large transformer secondaries or industrial busways — the 330 kA at 240 V is what you'd see on a big 208Y/120 V or 240 V delta service entrance. Temperature derating matters for panel layout: it carries the full 250 A up to 50 °C ambient, then steps down to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. ## What's built into the frame Communication function is onboard, and the ETU850 allows adjustable protection parameters — LSI (long-time, short-time, instantaneous) plus ground-fault pickup if you add the optional module. Power loss is 50.5 W maximum, so factor that into your enclosure thermal calculation. Rated insulation voltage is 800 V, and the operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA2225-7KP32-0BH0 SENTRON MCCB, 250 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0BH0 molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU850 release, 330 kA at 240 V.
