The 400 A frame means it's sized for main or large feeder breakers, not branch circuits. ## Derating and thermal reality 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. Plan the load accordingly or oversize the frame. Maximum power loss is 98.5 W, which adds to the enclosure heat budget. That means you get remote status indication and undervoltage protection without adding external relays. Communication function is present, so it can talk to a BMS or PLC for power monitoring. The basic switch is order code 3VA2340-6KP32-0AA0 — the UVR and aux switches are factory-integrated, not field-addable on this SKU. It's a panel-mount MCCB — no DIN rail, so plan for bolt-on bus bars or cable lugs. The trip indicator is present, which helps during troubleshooting: you see a mechanical flag or button pop when the breaker trips on overcurrent or short circuit.","metaTitle":"Siemens 3VA2340-6KP32-0CH0 SENTRON MCCB, 400A, 242kA at 240V","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0CH0 molded case circuit breaker, 400A continuous, 3-pole, 242kA IC at 240V.
