The interrupting ratings are the headline here: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. ## Thermal derating and real-world fit At 55 °C it derates to 375 A, at 60 °C to 350 A, at 65 °C to 325 A, and at 70 °C to 300 A. That matters when you're stuffing this into a crowded enclosure where ambient climbs — the 96 W max power loss adds heat you need to vent. The 110 mm depth, 138 mm width, and 248 mm height mean it fits standard SENTRON mounting bases and busbar systems; no oddball footprint. ## What's on board and what's not Comes with a communication function (likely PROFIBUS or PROFINET via the 3VA communication module) and an 'other measurement function' — the ETU850 can report load current and trip event data. No undervoltage release, no voltage trigger, no phase failure detection, no ground fault monitoring module built in. Mechanical endurance is 15,000 operations.","metaTitle":"Siemens 3VA2340-6KP32-0AG0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0AG0 molded case circuit breaker, 400 A, 3-pole, ETU850 release, 242 kA at 240 V.
