Breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V, so it can interrupt high fault currents across common industrial voltage levels without cascading upstream. Rated current holds at 40 A from 40 °C through 50 °C, then derates to 39 A at 55–60 °C and 37 A at 70 °C. Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a 3-pole footprint that fits standard MCCB mounting slots in SENTRON distribution boards or generic DIN-rail adapters. Maximum power loss is 10.8 W at rated load, which factors into enclosure thermal calculations when grouping multiple breakers in a sealed panel. ## Active lifecycle, no obsolescence concern","metaTitle":"Siemens 3VA1140-3EF36-0KA0 SENTRON MCCB, 40 A, 3-Pole, Shunt","metaDescription":"Siemens 3VA1140-3EF36-0KA0 SENTRON molded case circuit breaker, 40 A rated at 40°C, 3-pole, 75.6 kA at 240 V.
