The breaker holds its full 400 A rating up to 50 °C ambient; above that it derates linearly to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Dimensions are 248 mm high, 138 mm wide, 110 mm deep, which fits standard Siemens SENTRON mounting footprints; the 110 mm depth is shallow enough for most 400 mm deep enclosures without forcing a deeper can. ## Auxiliaries and communication It also includes a voltage trigger and a communication function — likely for remote monitoring or integration with a higher-level energy management system. No undervoltage release is fitted, so if your safety circuit requires UVR for machine isolation, you'll need to add it externally or spec a different variant.","metaTitle":"Siemens 3VA2340-5KP32-0JL0 SENTRON MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2340-5KP32-0JL0 molded case circuit breaker, 400 A continuous, 3-pole, 187 kA at 240 V.
