For a 400 A frame, these numbers place it in the high-interrupting category, suited for large transformer secondaries or bus-tie applications where fault current can exceed 100 kA. Thermal derating is modest: the breaker carries the full 400 A up to 50 °C ambient, then drops to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. ## Trip unit, release, and auxiliary options — what is and is not inside The supplied basic switch is 3VA2440-6HL32-0AA0. If your application requires undervoltage protection or remote status feedback, you will need a different suffix or field-installable accessory. The breaker has a voltage-trigger function (yes) but no trip indicator. Mechanical endurance is rated at 15,000 operations — typical for a 400 A frame used in infrequent switching (main disconnect or backup, not motor-start duty). The 110 mm depth is shallower than many 400 A MCCBs, which helps in shallow enclosures.","metaTitle":"Siemens 3VA2440-6HL32-0HA0 SENTRON MCCB, 400A, 242kA at 240V","metaDescription":"Siemens SENTRON 3VA2440-6HL32-0HA0 molded case circuit breaker, 400 A rated, 242 kA breaking at 240 V.
