Continuous current holds at 400 A up to 50 °C ambient; above that it derates to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. ## Integration and dimensions The 3VA2340-5KP32-0AG0 measures 248 mm high, 138 mm wide, and 110 mm deep — fits standard panel-mount cutouts for SENTRON 3VA frames. Communication function is onboard, supporting integration into a monitored distribution system. Power loss is 96 W maximum at rated load, so account for that in enclosure thermal calculations.","metaTitle":"Siemens 3VA2340-5KP32-0AG0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-5KP32-0AG0 molded case circuit breaker, 400 A continuous, 3-pole, 187 kA at 240 V.
