This is a line-protection device, not a motor-protection breaker — it's designed for feeder and main disconnect duty where selectivity and coordination matter. ## Interrupting capacity and voltage dependence Interrupting capacity drops sharply with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. That 690 V figure tells you this breaker is not intended for 690 V main service — it's a 400 V class device with generous headroom for high-fault applications at the lower voltages. ## Thermal derating profile 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. ## ETU850 electronic trip unit and communication Communication function is built in, so this breaker can report status and trip events to a higher-level control system — useful for a main breaker in a switchboard where you want remote trip indication without adding aux contacts. Dimensions are 248 mm height, 138 mm width, 110 mm depth.","metaTitle":"Siemens SENTRON 3VA2340-6KP32-0AA0 MCCB, 400 A, ETU850, 242","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0AA0 molded case circuit breaker, 400 A continuous, ETU850 electronic trip, 242 kA interrupting at 240 V.
