Above that it derates: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C. If the enclosure runs hot from other gear, size the feeder for the derated number, not the nameplate. IP40 on the front is typical for a panel-mounted MCCB; the line-side and load-side terminals are not sealed, so the enclosure provides the overall IP rating.","metaTitle":"Siemens 3VA2340-7HN32-0AA0 SENTRON MCCB, 400 A, 3-Pole, 330","metaDescription":"Siemens 3VA2340-7HN32-0AA0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, ETU350 release, 330 kA breaking at 240 V.
