This is the line protection version — meaning it is configured for feeder and main breaker duty, not motor branch circuit protection. The interrupting capacity reaches 330 kA at 240 V and remains at 242 kA at 415 V and 440 V, tapering to 187 kA at 500 V and 9 kA at 690 V. Above that, derate to 477 A at 55 °C, 455 A at 60 °C, 432 A at 65 °C, and 410 A at 70 °C. ## Communication and measurement capability This breaker includes communication function and other measurement function — the ETU850 supports optional communication modules (PROFIBUS, PROFINET, Modbus) for power monitoring and remote trip indication. That makes it suitable for a metered distribution board where you want energy data per feeder without a separate power meter. The electronic trip unit also provides adjustable time-current curves (tr max. 20 s) for coordination with downstream breakers.","metaTitle":"Siemens 3VA2450-7KP32-0AA0 SENTRON MCCB, 500A, ETU850, 330kA","metaDescription":"Siemens SENTRON 3VA2450-7KP32-0AA0 molded case circuit breaker, 500 A rated, ETU850 electronic trip, 3-pole, line protection.
