Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboard mounting bases. At 55 °C it derates to 38.4 A, and at 70 °C it holds 36 A — a gentle slope that keeps the breaker usable in hot switchgear rooms without oversizing. Maximum power loss is 13.3 W, so in a multi-breaker panel the cumulative heat stays manageable without forced ventilation.","metaTitle":"Siemens 3VA1040-3ED36-0CC0 SENTRON MCCB, 40 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1040-3ED36-0CC0 molded case circuit breaker, 40 A, 3-pole, 75.6 kA interrupting at 240 V.
