At 415 V it still holds 187 kA, and at 690 V it derates to 7.5 kA, so the voltage-dependent curve is what you coordinate against, not the headline number. Three-pole design, line protection application — this is the main breaker for a feeder or large motor branch, not a downstream distribution breaker. The 400 A frame carries full current from 40 °C up to 50 °C without derating; above that, the thermal curve drops to 385 A at 55 °C and 340 A at 70 °C. ## Auxiliary switching and trip indication The trip alarm signals a fault trip separately from the aux contact that tracks the breaker's on/off position — useful for remote SCADA or DCS alarming on a paper machine line where an unplanned trip kills tonnes on the reel. The 110 mm depth is the mounting depth behind the panel door — factor that into enclosure sizing if retrofitting into an existing MCC bucket.","metaTitle":"Siemens 3VA2340-6HN32-0AG0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2340-6HN32-0AG0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA interrupting at 240 V.
