This makes the breaker suitable for systems requiring selective coordination or where neutral protection must match the load profile. ## Breaking Capacity and Derating Rated breaking capacity is 440 kA at 415 V and 187 kA at 690 V — figures that place this MCCB in the high-interrupting category for large industrial feeds or transformer secondaries where fault current can exceed 200 kA. Current rating holds at 250 A from 40 °C through 50 °C, then derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. An optional motor drive is available for remote operation. Maximum power loss is 48 W at rated current — factor this into the panel thermal budget.","metaTitle":"Siemens 3VA2225-0HM42-0AA0 SENTRON MCCB, 250A, 4-Pole, ETU33","metaDescription":"Siemens SENTRON 3VA2225-0HM42-0AA0 molded case circuit breaker, 250 A rated, 4-pole, ETU330 electronic trip unit.
