The interrupting ratings are 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V, so it handles high-fault utility feeds and large motor branch circuits where the available fault current is substantial. The auxiliary contact block is a 2+1 HQ configuration (two auxiliary switches plus one trip-alarm switch), and the integrated shunt trip (STL) release is order code 3VA9688-0BL30. The N-conductor protection is set to 100%, meaning the neutral pole is fully rated and switches with the phase poles — important for 4-wire systems where the neutral carries load current. Above that it derates: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. Dimensions are 140 mm wide × 158 mm high × 70 mm deep.","metaTitle":"Siemens 3VA1225-4GF42-0HH0 SENTRON MCCB, 250 A, 4-Pole, 70 m","metaDescription":"Siemens 3VA1225-4GF42-0HH0 SENTRON molded case circuit breaker, 250 A rated continuous current, 4-pole, line protection, TM240 release, 121 kA at 240 V.
