IP40 front protection keeps tools and fingers out. The 40 A rating holds flat from 40 °C to 50 °C, then derates to 39 A at 55–60 °C and 38 A at 65 °C, 37 A at 70 °C — so in a warm panel (say 55 °C ambient) you lose only 1 A, but at 70 °C you're down to 37 A continuous. Maximum power loss is 10.8 W. Operating range is -25 °C to 70 °C; storage range -40 °C to 80 °C — fine for unheated warehouses as long as the breaker is not energized below -25 °C. The part is specified into new panels across the 3VA platform.","metaTitle":"Siemens 3VA1040-3ED46-0AA0 SENTRON MCCB, 40A 4P, 75.6kA at 2","metaDescription":"Siemens SENTRON 3VA1040-3ED46-0AA0 molded case circuit breaker, 40A rated at 40°C, 4 poles, 75.6kA breaking at 240V.
