The breaking capacity reaches 242 kA at 240 V AC and 187 kA at 415 V, tapering to 7.5 kA at 690 V — this is a distribution-class breaker sized for high-fault main feeders, not motor branch circuits. ## Current ratings and thermal derating The breaker holds 400 A continuously up to 50 °C ambient. Above that, derating is linear: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Maximum power loss is 98.5 W.","metaTitle":"Siemens 3VA2340-6KP32-0BL0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0BL0 molded case circuit breaker, 400 A continuous, 3-pole, adjustable trip 600–4000 A, breaking capacity 242 kA at 240 V.
