Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415 V, 85 kA at 440 V, 55 kA at 500 V, and 9 kA at 690 V — which means at typical 400 V distribution voltages it clears fault currents up to 187 kA without upstream coordination issues. Thermal derating is published per the datasheet: the breaker holds 500 A through 50 °C, then drops to 477 A at 55 °C, 455 A at 60 °C, 432 A at 65 °C, and 410 A at 70 °C. The breaker measures 184 mm wide, 248 mm tall, and 110 mm deep. The ETU560 release supports communication functions, which allows remote monitoring and trip-data retrieval via the SENTRON communication bus.","metaTitle":"Siemens 3VA2450-6JQ42-0AA0 SENTRON MCCB, 500 A, 4-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2450-6JQ42-0AA0 molded case circuit breaker, 500 A continuous, 4-pole, ETU560 release.
