The 40 A rating holds flat from 40 °C through 50 °C, then derates to 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. If the panel ambient runs above 50 °C, the continuous load must be backed off accordingly — the 36 A floor at 70 °C still leaves headroom for a 30 A continuous load, but a full 40 A draw at 70 °C would nuisance-trip. The 76.2 mm width and 70 mm depth (130 mm height) fit a standard 3-pole MCCB footprint on the DIN rail or panel-mount plate; the IP40 front protection keeps dust out of the enclosure face.","metaTitle":"Siemens 3VA1140-6EF32-0AD0 SENTRON MCCB, 40 A, 220 kA at 240","metaDescription":"Siemens 3VA1140-6EF32-0AD0 SENTRON molded case circuit breaker, 3-pole, 40 A rated continuous current, TM240 release.
