At 500 V and 690 V it still holds 7.5 kA, so it works across 400 V class and 690 V industrial systems. At 55 °C it derates to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. That's a shallow curve — you lose only 3 A across a 30 °C rise — so in a warm panel near the top of the enclosure you still get nearly full rated current. The maximum power loss is 10.8 W, which is manageable for a 3-pole MCCB at this frame size; no forced cooling needed in a standard IP40 front panel. The TM120M release is factory-set — no field adjustment of the thermal curve, so verify the motor FLA matches the 40 A rating before you install.","metaTitle":"Siemens 3VA1140-6MH36-0AA0 SENTRON MCCB, 40 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1140-6MH36-0AA0 molded case circuit breaker, 3-pole, 40 A rated, 220 kA at 240 V.
