Breaking capacity is substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. That covers most industrial service-entrance and feeder applications where high fault current is a given. ## Thermal derating — plan your panel ambient At 55 °C it derates to 375 A, at 60 °C to 350 A, at 65 °C to 325 A, and at 70 °C to 300 A. Maximum power loss is 96 W, so ventilation or spacing matters in a dense enclosure. Dimensions are 110 mm deep, 138 mm wide, 248 mm tall. ## What's inside — trip unit and releases It's field-adjustable and supports communication, so you can read trip events and settings remotely. The integrated shunt trip (STL) is part number 3VA9688-0BL33 — if you need a spare release, that's the order code. The base switch without the shunt trip is 3VA2340-6JP32-0AA0.","metaTitle":"Siemens 3VA2340-6JP32-0KA0 SENTRON MCCB, 400 A, 3-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2340-6JP32-0KA0 molded case circuit breaker, 400 A rated continuous current, 3-pole, ETU550 electronic trip unit, breaking capacity up to 242 kA at 240 V.
