Interrupting capacity hits 242 kA at 240 V, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V — so it clears high-fault scenarios on the secondary side of a distribution transformer or at a large motor control center without cascading upstream. Thermal derating kicks in above 50 °C: still holds 400 A at 50 °C, then 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Built-in undervoltage release (UVR) and a communication function let this breaker integrate with a BMS or PLC for remote trip and status monitoring. The auxiliary contact version carries 2 HQ auxiliary switches; the integrated auxiliary trip unit is order code 3VA9608-0BB11. No ground-fault monitoring or phase failure detection on this variant — specify those separately if needed. Basic switch assembly is order code 3VA2340-6KP32-0AA0; the 3VA2340-6KP32-0BC0 is the fully-assembled MCCB with ETU850 and UVR pre-installed. Insulation voltage (Ui) rated at 800 V.","metaTitle":"Siemens 3VA2340-6KP32-0BC0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens 3VA2340-6KP32-0BC0 SENTRON molded case circuit breaker, 400 A, 3-pole, ETU850 trip unit, 242 kA at 240 V.
