At 415 V and 440 V it still holds 187 kA, dropping to 121 kA at 500 V and 7.5 kA at 690 V; that steep roll-off above 500 V means you verify the available fault current at the point of installation before committing the BOM line. Thermal derating is baked into the spec: the breaker carries 400 A continuously at ambient up to 50 °C, then drops to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. The 96 W maximum power loss at rated load matters for enclosure heat-rise calculations; that's the heat you need to vent through the gland plate or forced-air path. 248 mm tall, 138 mm wide, 110 mm deep. 3-pole form factor. Availability and pricing confirmed at quote time. ## Integration and compliance notes No undervoltage release and no auxiliary release fitted. Communication function onboard. The trip indicator (a mechanical flag visible on the front cover) gives a clear visual that the breaker has tripped on fault, not just been switched off — useful for a technician walking a lineup.","metaTitle":"Siemens SENTRON 3VA2340-6JQ32-0AF0 MCCB, 600-4000 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0AF0 molded case circuit breaker. 3-pole, 600-4000 A adjustable trip. 242 kA at 240 V.
