Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that place it in the high-fault category for industrial main or feeder duty where available fault current exceeds typical 25–65 kA MCCB ratings. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard Siemens SENTRON 3VA mounting bases and busbar systems without adapter plates. Maximum power dissipation is 10.8 W, which should be factored into enclosure thermal calculations when grouping multiple breakers in a sealed panel.","metaTitle":"Siemens 3VA1140-6EF32-0KC0 SENTRON MCCB, 40A, 3-Pole, 220kA","metaDescription":"Siemens SENTRON 3VA1140-6EF32-0KC0 molded case circuit breaker, 40A rated, 3-pole, 220 kA at 240 V.
