It carries a continuous current of 400 A across the full ambient range from 40 °C to 70 °C — no derating needed within that window. ## Breaking capacity across voltage levels At 415 V and 440 V the breaking capacity is 121 kA; at 500 V it drops to 75.6 kA, and at 690 V it is 9 kA. The 9 kA at 690 V is a sharp reduction — if your system runs at 690 V, verify the available fault current stays under that limit. The lifecycle stage is listed as current — meaning the manufacturer still produces this order code. No successor has been announced. ## Panel integration and dimensions The breaker measures 138 mm wide, 248 mm high, and 110 mm deep — a standard footprint for a 400 A frame. ## Built-in auxiliary and release options The trip indicator provides local visual confirmation of a fault trip.","metaTitle":"SENTRON 3VA2440-5HN32-0DH0 MCCB, 400 A, 187 kA at 240 V","metaDescription":"SENTRON 3VA2440-5HN32-0DHO molded case circuit breaker, 400 A rated, 187 kA breaking capacity at 240 VAC. 3-pole, line protection, undervoltage release.
