The 40 kA at 690 V matters if you are feeding a 690 V motor control center; most MCCBs in this frame size drop off faster above 500 V. ## Thermal derating — the real-world current you can run Above that it derates: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. ## Auxiliaries and releases — what is built in and what is not The integrated auxiliary trip is order code 3VA9688-0BL32. No undervoltage release is installed, and there is no ground-fault monitoring module — if you need GF protection, you add an external module or choose a different variant. The basic switch core is 3VA2340-6KP32-0AA0, so the -0JH0 suffix adds the shunt trip and the HQ auxiliary contact block. That 110 mm depth is the front-to-back envelope including the arc chamber — measure your enclosure depth before ordering, especially if you are retrofitting into a panel originally designed for a shallower frame. The breaker mounts via the standard SENTRON 3VA base plate; no special adapter needed for most Siemens switchboard and distribution panel layouts.","metaTitle":"Siemens 3VA2340-6KP32-0JH0 SENTRON MCCB, 400 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0JH0 molded case circuit breaker, 400 A rated current, 242 kA breaking capacity at 240 V.
