Thermal derating is straightforward: full 250 A from 40 °C through 50 °C ambient, then 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Dimensions: 181 mm height, 105 mm width, 86 mm depth. ## Trip unit and protection features The ETU350 is an electronic trip unit with LSIG protection — long-time, short-time, instantaneous, and ground-fault — though this specific variant ships without ground-fault monitoring (the 'Without' designation on the ground-fault version field). That means you get adjustable L, S, and I curves but no built-in ground-fault element. If you need ground-fault protection, you'd step to a different order code in the 3VA2 family.","metaTitle":"Siemens 3VA2225-5HN32-0AH0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2225-5HN32-0AH0 SENTRON molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU350 electronic trip unit, line protection.
