At 415 V it still handles 154 kA, and at 690 V it holds 17 kA. Rated insulation voltage is 800 V, giving headroom for 480 V and 600 V class systems. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm high. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for Siemens SENTRON 3VA frames — it mounts via screw terminals to a backplate or DIN rail adapter. Verify the existing panel's bus bar spacing and mounting hole pattern against these dimensions before committing the BOM line. The breaker holds its full 40 A rating from 40 °C through 50 °C. At 55 °C it derates to 39 A, holding there through 60 °C. At 65 °C it drops to 38 A, and at 70 °C to 37 A. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss is 10.8 W.","metaTitle":"Siemens 3VA1140-6EF36-0KH0 SENTRON MCCB, 40 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1140-6EF36-0KH0 molded case circuit breaker, 40 A, 3-pole, 220 kA breaking capacity at 240 V.
