Breaking capacity is the headline number that governs fault-current coordination: 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That 220 kA at 240 V places it in the high-interrupting category for North American 240/277 V distribution — it clears a bolted fault upstream of the main without cascading, so downstream breakers can be rated lower. ## Thermal derating and continuous current At 55 °C it drops to 243 A, at 60 °C to 237 A, at 65 °C to 230 A, and at 70 °C to 223 A. ## Shunt trip and auxiliary release configuration The breaker can be remotely tripped by energizing the shunt coil, standard for emergency-stop circuits or fire-alarm shunt-down.","metaTitle":"Siemens SENTRON 3VA1225-6EF32-0KA0 MCCB, 250A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1225-6EF32-0KA0 molded case circuit breaker, 3-pole, 250A rated, 220kA breaking capacity at 240V AC.
