Breaking capacity hits 242 kA at 240 V, drops to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 7.5 kA at 690 V. Thermal derating is published: full 400 A holds through 50 °C, then steps down to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. The breaker includes communication and other measurement functions, meaning it can report status and metering data upstream — useful for a plant-floor energy monitoring scheme or a predictive-maintenance dashboard. Dimensions: 248 mm height, 138 mm width, 110 mm depth. That 138 mm width is the 3-pole frame footprint — verify your existing busbar spacing and enclosure depth before cutting gland plates. The 110 mm depth means it clears most 200 mm deep enclosures, but check the handle throw arc if you're mounting close to the door. Power loss is 96 W maximum at rated load. That's a non-trivial heat source inside a sealed enclosure — account for it in your thermal calculation, especially if the panel also carries drives or transformers.","metaTitle":"Siemens 3VA2340-6KP32-0AF0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0AF0 molded case circuit breaker, 400 A continuous, 3-pole, adjustable trip 600–4000 A, breaking capacity up to 242 kA at 240 V.
