Its interrupting capacity hits 242 kA at 240 V AC and 187 kA at 415/440 V, dropping to 121 kA at 500 V and 7.5 kA at 690 V — so for most 400 V class distribution panels this breaker clears faults well into the high-fault zone without cascading upstream. ## Thermal derating and ambient compensation 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. ## Auxiliaries and communication This variant ships with two HQ auxiliary switches and an undervoltage release (UVR) fitted. Communication function is onboard, so it can report status or accept remote commands over the SENTRON bus system. Listed as current production. ## Physical fit","metaTitle":"Siemens 3VA2340-6JQ32-0CC0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0CC0 molded case circuit breaker, 400 A rated, 242 kA breaking at 240 V.
