At 55 °C it derates to 375 A, at 60 °C to 350 A, at 65 °C to 325 A, and at 70 °C to 300 A — the maximum operating ambient is 70 °C. ## Built-in undervoltage release The communication function is present, enabling integration with higher-level monitoring systems. The 138 mm width is the 3-pole footprint; verify the busbar or lug kit spacing matches the existing panel layout if replacing a different MCCB brand. Maximum power loss is 98.5 W at rated current.","metaTitle":"Siemens 3VA2340-6KP32-0CA0 SENTRON MCCB, 400 A, 242 kA","metaDescription":"Siemens 3VA2340-6KP32-0CA0 SENTRON molded case circuit breaker, 400 A rated, 242 kA at 240 V, line protection with undervoltage release.
