That 250 A frame sits in a 4-pole package (70 mm deep, 140 mm wide, 158 mm tall) designed for line protection in distribution panels, not motor-starting duty. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. ## Built-in accessories and trip functions The trip indicator and voltage trigger are present; undervoltage release and ground-fault monitoring are not. Communication function is absent — this is a standalone breaker, not a metering or networked unit.","metaTitle":"Siemens 3VA1225-5GF42-0JH0 SENTRON MCCB, 250 A, 4-Pole, 70 m","metaDescription":"Siemens 3VA1225-5GF42-0JH0 SENTRON molded case circuit breaker, 250 A, 4-pole, breaking capacity 187 kA at 240 V.
