At 55 °C it derates to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A — no surprise for a thermal-magnetic breaker, but if you're packing this into a high-density switchboard with ambient near 60 °C, the effective continuous current drops to 39 A. The frame dissipates 10.8 W max at rated load. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — fits standard 3-pole MCCB panel cutouts.","metaTitle":"Siemens 3VA1140-5ED32-0AA0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5ED32-0AA0 molded case circuit breaker, 40 A, 3-pole, TM210 release, 187 kA interrupting at 240 VAC.
