Rated 400 A continuous up to 50 °C ambient. Above that it derates: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. Maximum power loss is 96 W, which adds to the enclosure heat budget. Factor that into your thermal calculation if the breaker is in a sealed cabinet. That depth is the body depth behind the panel face — check your gland plate clearance and door swing before cutting the mounting hole. The storage range is wider because it's not dissipating heat when shelved.","metaTitle":"Siemens 3VA2340-7HL32-0AF0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0AF0 molded case circuit breaker, 400 A continuous, 3-pole, 110 mm depth.
