The ETU850 electronic trip unit handles line protection duty with communication capability, making it a fit for main or feeder breakers in LV switchboards where selective coordination matters. The 400 A rating at 70 °C means this breaker handles full load in a warm enclosure without downsizing — a common pain point with breakers that derate above 40 °C.","metaTitle":"Siemens 3VA2440-6KP32-0AA0 SENTRON MCCB, 400A, 242kA at 240V","metaDescription":"Siemens 3VA2440-6KP32-0AA0 SENTRON molded case circuit breaker, 400A rated, 242kA breaking at 240V, ETU850 release, 3-pole.
