The 250 A frame carries the full load without derating up to 50 °C; above that, the thermal curve drops to 241 A at 55 °C and 213 A at 70 °C, so panel ambient matters if you're pushing the rating. Breaking capacity is 121 kA at 240 V, 75.6 kA at 415/440 V, 52.5 kA at 500 V, and 4.5 kA at 690 V. Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for a 250 A frame. Maximum power loss is 48 W at rated current. That's moderate for a 250 A MCCB — enough to consider spacing in a dense panel but not a showstopper. The 48 W figure is the worst-case heat dissipation the breaker sheds into the enclosure, so factor it into your panel thermal calculation if you're stacking multiple breakers.","metaTitle":"Siemens SENTRON 3VA2225-4HL32-0AA0 MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2225-4HL32-0AA0 molded case circuit breaker, 250 A continuous, 3-pole, ETU320 release.
