That interrupting figure drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 7.5 kA at 690 V — so the available fault current at the panel's service voltage decides whether this breaker holds or you need a higher-rated frame. The continuous current holds flat at 400 A from 40 °C through 50 °C, then derates to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. If the enclosure runs hot, that derating curve is the one that governs the real load you can hang on it. The UVR means the breaker trips when control voltage drops — common in safety circuits or remote shunt-trip applications. Communication function is onboard, so it can talk to a higher-level system for metering or remote trip indication. The breaker measures 110 mm deep, 138 mm wide, and 248 mm tall.","metaTitle":"SENTRON 3VA2340-5JQ32-0BH0 MCCB, 400 A, 187 kA at 240 V","metaDescription":"SENTRON 3VA2340-5JQ32-0BH0 molded case circuit breaker, 3-pole, 400 A rated, 187 kA interrupting at 240 V.
