Interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, dropping to 121 kA at 500 V and 7.5 kA at 690 V — the 690 V figure is the limiting case for high-voltage industrial systems, so verify the available fault current at your service voltage against these ratings. Current-carrying capacity is temperature-dependent: the breaker is rated 400 A 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. Maximum power loss is 96 W. The MCCB measures 110 mm deep, 138 mm wide, and 248 mm high. It is a panel-mount device — no DIN-rail clip. The 3-pole footprint is standard for this class; verify cutout dimensions against the existing switchboard or enclosure gland plate before ordering.","metaTitle":"Siemens 3VA2340-6JQ32-0AB0 SENTRON MCCB, 4000 A, 3-Pole, Lin","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0AB0 molded case circuit breaker, 3-pole, adjustable 600–4000 A, interrupting 242 kA at 240 V.
