At 415 V and 440 V the rating holds at 121 kA, and it still delivers 75.6 kA at 500 V, so it covers most industrial voltage levels without derating the interrupting rating until you hit 690 V (17 kA). The 400 A rating holds flat from 40 °C through 50 °C, then derates linearly to 300 A at 70 °C. If your panel ambient runs above 50 °C, size the breaker for the derated value — the 375 A at 55 °C and 350 A at 60 °C are the real-world limits, not the nameplate 400 A. ## Communication and auxiliary functions The communication function and other measurement function indicate this variant supports remote monitoring and parameterization — likely via the SENTRON communication modules (PROFIBUS, PROFINET, or Modbus), though the specific protocol is not listed here. For frequent switching duty, factor in the electrical endurance curve (not provided here) which will be lower under load.","metaTitle":"Siemens 3VA2340-5KP32-0DL0 SENTRON MCCB, 400 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-5KP32-0DL0 molded case circuit breaker, 400 A rated, 187 kA breaking at 240 V.
