Rated interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — enough headroom for most industrial service-entrance or feeder applications where fault current runs high. At 690 V it's still rated 7.5 kA, so it handles line-to-line faults on 480 V systems without issue. At 55 °C it derates to 38.4 A, at 60 °C to 37.6 A, and at 70 °C to 36 A. That's a shallow curve; you lose only 4 A over a 20 °C rise, so it's forgiving in a warm panel next to transformers or drives. Max operating temp is 70 °C, storage range -40 to 80 °C. Power loss tops out at 10.8 W — that's the heat it dumps into the enclosure. For a 40 A MCCB that's modest; you won't need forced ventilation in a typical 600 x 800 mm panel unless you pack a dozen of them side by side. Three poles, line-side lugs top and bottom; the shunt trip (STL) is built in, so you don't need an external trip module.","metaTitle":"Siemens 3VA1040-3ED36-0JA0 MCCB, 40 A, 3-Pole, Shunt Trip","metaDescription":"Siemens SENTRON 3VA1040-3ED36-0JA0 molded case circuit breaker, 40 A rated, 3-pole, 75.6 kA at 240 V, TM210 release, shunt trip.
