At 415/440 V the rating drops to 187 kA, and at 690 V it holds at 7.5 kA, which still covers most industrial distribution panels. The thermal-magnetic trip unit is adjustable from 80 A to 400 A full scale, so you can dial it down to match a downstream load without swapping the breaker body. Above that it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. The 138 mm width, 248 mm height, and 110 mm depth fit standard SENTRON 3VA mounting footprints; it bolts directly onto the backplate or into a fixed draw-out cradle without adapters.","metaTitle":"Siemens 3VA2340-6JQ32-0HL0 SENTRON MCCB, 400 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0HL0 molded case circuit breaker, 400 A rated at 40 °C, 242 kA breaking at 240 V.
