At 415 VAC the interrupting rating is 154 kA, dropping to 121 kA at 440 VAC, and 17 kA at both 500 VAC and 690 VAC. ## Thermal Derating and Continuous Current At 55 °C it derates to 39 A, holds 39 A at 60 °C, then drops to 38 A at 65 °C and 37 A at 70 °C (–). The 3VA1140-6EF32-0AB0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 3-pole footprint matches the SENTRON 3VA family; if replacing an existing 3VA1110 variant, verify the lug kit and accessory slot compatibility — the auxiliary switch design here is 2 auxiliary switches HP, which occupies the same accessory bay as the 3VA1110 series.","metaTitle":"Siemens 3VA1140-6EF32-0AB0 SENTRON MCCB, 40 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1140-6EF32-0AB0 molded case circuit breaker, 40 A, 3-pole, 220 kA breaking capacity at 240 VAC.
