The 70 mm depth and 101.6 mm width fit standard MCCB panel cutouts without extra gland-plate work. ## Interrupting ratings across voltage levels The breaker carries symmetrical interrupting ratings of 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at 500 V and 690 V. Continuous current holds at 125 A from 40 °C up to 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. In a hot mill or foundry panel where ambient near the breaker hits 55 °C, you still get 122 A — only a 2.4% drop from the 40 °C rating. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. Front face is IP40 rated — splash protection on the front, but the breaker lives inside a closed panel or enclosure. No communication module on board; motor drive is available as an optional extension.","metaTitle":"Siemens 3VA1112-4EF46-0AA0 SENTRON MCCB, 125A, 4-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1112-4EF46-0AA0 molded case circuit breaker, 125A, 4-pole, 121 kA at 240 V.
