Its interrupting capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V — figures that govern selectivity coordination in high-fault industrial distribution. The breaker holds its 400 A rating through 50 °C ambient; above that it derates linearly to 300 A at 70 °C. Physical dimensions are 248 mm high, 138 mm wide, 110 mm deep, which fits standard SENTRON 3VA panel cutouts and busbar centers. Operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.","metaTitle":"Siemens 3VA2340-6JQ32-0AE0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0AE0 molded case circuit breaker, 400 A, 3-pole, 242 kA at 240 VAC.
