It provides fault protection and isolation for power distribution in industrial switchboards, panelboards, and motor control centers. The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V, dropping to 11.9 kA at 690 V. Above that, it derates linearly: 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C. ## Auxiliary and release configuration ## Physical integration The 3-pole frame mounts into standard switchboard or panelboard cutouts; the 110 mm depth fits typical enclosure depths without interference with the back panel or door-mounted devices.","metaTitle":"Siemens 3VA1340-5EF32-0DG0 SENTRON MCCB, 400A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1340-5EF32-0DG0 molded case circuit breaker. 400A rated current at 40°C, 3-pole, 187kA interrupting at 240V.
