The 400 A rating holds across ambient temperatures up to 50 °C; above that it derates to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C — so if your panel runs hot, the continuous current you can actually pull is lower than the nameplate 400 A. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. It includes phase failure detection, a trip indicator, and a voltage trigger. A shunt trip (STL) is integrated as the auxiliary release. The shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit. The auxiliary switches and trip alarm switch give status feedback to a control system or HMI.","metaTitle":"Siemens 3VA2440-5MN32-0JH0 MCCB, 400A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2440-5MN32-0JH0 molded case circuit breaker, 400A rated continuous current, 187kA breaking capacity at 240V AC.
