That means in a 40 °C panel you get full 400 A; if the enclosure runs hotter, the breaker self-limits without nuisance tripping. Breaking capacity is the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. Those are high-interrupting ratings — the breaker clears a fault without cascading upstream, which matters when you are coordinating a main or feeder in a high-fault installation. The electronic trip unit is an ETU850, which brings communication capability — this MCCB is not a dumb thermal-magnetic; it can report status and integrate into a monitored distribution system. ## Physical fit and integration notes Dimensions: 248 mm height, 138 mm width, 110 mm depth. The storage limits govern handling and warehousing, not running conditions. The basic switch (the interrupting module) is order code 3VA2340-6KP32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL30 — these are the replaceable sub-assemblies if you ever need to service the breaker rather than swap the whole unit.","metaTitle":"Siemens 3VA2340-6KP32-0HL0 SENTRON MCCB, 400 A, 242 kA","metaDescription":"Siemens 3VA2340-6KP32-0HL0 SENTRON molded case circuit breaker, 400 A rated at 40 °C, 242 kA breaking at 240 V.
