Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. The 250 A rating holds flat from 40 °C through 50 °C, then derates gradually to 223 A at 70 °C. The integrated auxiliary trip is a separate order code 3VA9608-0BB24. If your BOM already calls that out, it matches this breaker. Dimensions 70 mm deep, 140 mm wide, 158 mm high. No auxiliary contact version, no communication function, no phase failure detection, no ground fault monitoring on this variant — if you need those, you are looking at a different suffix.","metaTitle":"Siemens 3VA1225-5EF42-0CA0 SENTRON MCCB, 250 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1225-5EF42-0CA0 SENTRON molded case circuit breaker, 250 A rated continuous current, 4-pole, TM240 release, 187 kA at 240 V.
