The 2-pole configuration and TM210 thermal-magnetic release provide LI (long-time and instantaneous) protection, with a fixed instantaneous pickup at 400 A. For a data center or industrial feeder, that means you can place this breaker close to the transformer secondary without worrying about cascading failure into upstream gear. The 3VA1140-5ED22-0AA0 measures 70 mm deep, 50.8 mm wide, and 130 mm tall — a compact 2-pole footprint that fits standard DIN-rail or panel-mount enclosures. Front-face protection is IP40, meaning tools or fingers won't accidentally contact live parts during commissioning. Power loss is 7.2 W maximum, so thermal rise inside a sealed panel stays manageable without forced ventilation.","metaTitle":"Siemens 3VA1140-5ED22-0AA0 SENTRON MCCB, 40 A, 2-Pole, 187 k","metaDescription":"Siemens 3VA1140-5ED22-0AA0 SENTRON molded case circuit breaker, 40 A rated at 40 °C, 2-pole, 187 kA at 240 V.
