The 690 V rating drops to 7.5 kA, so confirm your high-voltage system's short-circuit capacity if running above 600 V. ## Thermal derating curve — real-world current 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. The case measures 248 mm tall, 138 mm wide, and 110 mm deep. That 110 mm depth is the dimension to watch when fitting into a shallow enclosure or against a backplate with bus bars running behind it. The ETU550 electronic trip unit includes communication capability (PROFIBUS or similar via a communication module), so it fits into a monitored distribution scheme. Insulation voltage rated 800 V, power loss 96 W at full load — factor that into your enclosure ventilation.","metaTitle":"Siemens SENTRON 3VA2340-6JP32-0AA0 MCCB, 400A, 3-Pole, ETU55","metaDescription":"Siemens 3VA2340-6JP32-0AA0 SENTRON molded case circuit breaker, 400A continuous, 3-pole, ETU550 release, 242kA at 240V.
