The steep drop at 690 V is the giveaway that this is a 600 V class frame pushed to its limit — don't spec it for a 690 V primary feeder unless the fault current is well under 7.5 kA. ## Thermal derating — the real ampacity in a hot panel At 55 °C it drops to 385 A, at 60 °C to 370 A, at 65 °C to 355 A, and at 70 °C to 340 A. If this breaker sits next to a transformer or a row of contactors that push the enclosure air above 50 °C, size the feeder for the derated number — the nameplate 400 A is only good in a cool cabinet. ## Physical fit and auxiliary wiring The case measures 138 mm wide, 248 mm tall, and 110 mm deep — a standard 3-pole MCCB footprint for a 400 A frame.","metaTitle":"Siemens SENTRON 3VA2340-6HL32-0AF0 MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6HL32-0AF0 3-pole molded case circuit breaker, 400 A rated, 600–4000 A trip range, 242 kA at 240 VAC.
