The 500 A rating holds flat from 40 °C to 50 °C, then derates to 477 A at 55 °C and 410 A at 70 °C. The 242 kA at 240 V and 187 kA at 415 V cover most North American and European fault-current scenarios; at 690 V the capacity drops to 9 kA, so this breaker is not a primary choice for 690 V systems with high available fault current. The ETU550 electronic trip unit supports communication (Communication Function: Yes), enabling power monitoring and remote trip indication via the SENTRON bus. No ground-fault monitoring is built in — if GF protection is required, you need an external module or a different variant. ## Panel integration The 3VA2450-6JP42-0AA0 measures 184 mm wide × 248 mm high × 110 mm deep.","metaTitle":"Siemens 3VA2450-6JP42-0AA0 SENTRON MCCB, 500 A, 4-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2450-6JP42-0AA0 molded case circuit breaker, 500 A, 4-pole, ETU550 release, 242 kA at 240 V.
