The IP40 front protection means it's fine for indoor panel mounting but not washdown areas. At 240 V, the 76 kA rating handles heavy fault currents typical in industrial service entrance or sub-distribution boards. The thermal derating curve is tight: it holds 40 A from 40 °C through 50 °C, drops to 39 A at 55 °C and 60 °C, then 38 A at 65 °C and 37 A at 70 °C. That means in a warm panel you lose only 3 A at the top of the operating range — not enough to force a upsizing in most designs.","metaTitle":"Siemens 3VA1140-3ED22-0AA0 SENTRON MCCB, 2-pole, 40 A, 76 kA","metaDescription":"Siemens 3VA1140-3ED22-0AA0 SENTRON 2-pole molded case circuit breaker, 40 A rated, 76 kA at 240 V, 53 kA at 415 V.
