Thermal derating is minimal through 50 °C — still rated 40 A — then drops only 1 A per 5 °C step to 37 A at 70 °C. That means in a warm panel (say 55 °C ambient), you still get 39 A continuous, so no need to oversize for typical enclosure heat rise. At 70 mm deep, 101.6 mm wide, and 130 mm tall, this breaker fits the standard SENTRON 3VA footprint. The 101.6 mm width (4 inches) is the critical dimension for multi-pole grouping in a distribution board — four poles at that width means it occupies a 4-module slot in a Siemens panelboard or a standard DIN-rail enclosure with appropriate busbar spacing. Front face carries IP40 protection — suitable for general indoor panel use where tools or fingers won't contact live parts. Lifecycle status is current production. This is an active catalog item in the SENTRON 3VA series.","metaTitle":"Siemens 3VA1140-6GD46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1140-6GD46-0AA0 molded case circuit breaker, 40 A rated, 4-pole, TM210 release.
