Communication function is built in, so it can report status to a BMS or PLC without an add-on module. ## Thermal derating — the real-world current 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. The interrupting rating drops as system voltage rises — standard for any MCCB. At 240 V it clears 242 kA; at 415 V and 440 V it handles 187 kA (–); at 500 V it is 121 kA; at 690 V it falls to 7.5 kA. For a 480 V or 600 V class installation, the 121 kA at 500 V is the relevant figure — still very high, but not the headline 242 kA. The minimum trip setting is 600 A, maximum 4 000 A, so the breaker is adjustable for cable protection coordination. That is a standard SENTRON 3VA form factor — it mounts on a backplate or DIN rail via the breaker's own base, not a separate adapter. Verify the depth clearance inside the enclosure: 110 mm plus wiring space for the line and load lugs.","metaTitle":"Siemens SENTRON 3VA2340-6JQ32-0JA0 MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0JA0 molded case circuit breaker, 400 A rated, 242 kA breaking at 240 V.
