Thermal derating is modest: full 40 A through 50 °C, then 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C. Power loss at rated load is 10.8 W maximum — useful to know for enclosure thermal calculations when grouping several breakers. ## Auxiliary and release configuration That gives you remote tripping capability and two separate signal paths for status feedback — one for the breaker position, one dedicated to the trip event. Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth. The supplied basic switch is order code 3VA11406EF320AA0, which is the internal mechanism; the -0JH0 suffix specifies the factory-fitted shunt trip and auxiliary switch combination.","metaTitle":"Siemens 3VA1140-6EF32-0JH0 SENTRON MCCB, 40 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1140-6EF32-0JH0 molded case circuit breaker, 40 A, 3-pole, interrupting capacity 220 kA at 240 V.
