It delivers a 242 kA breaking capacity at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V — which means it can safely interrupt fault currents up to those levels without cascading upstream, a critical parameter for panel SCCR compliance under UL 508A. Thermal derating is specified across the operating range: the breaker carries a full 400 A continuously at ambient temperatures up to 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. This curve governs the actual conductor and enclosure fill sizing — a panel builder must account for the derated value at the enclosure's internal ambient, not the nameplate 400 A, when coordinating with downstream distribution. Maximum power loss is 98.5 W, which contributes to the enclosure's thermal budget. Dimensions are 248 mm height, 138 mm width, and 110 mm depth. Verify the 110 mm depth against enclosure gland-plate clearance — this is a through-panel mounted device, not a plug-in unit.","metaTitle":"Siemens 3VA2340-6JQ32-0BA0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0BA0 molded case circuit breaker, 400 A rated, 242 kA breaking at 240 V.
