It accepts stranded copper conductors from 6 AWG up to 350 kcmil, making it the correct termination accessory when landing larger feeder or distribution cables on that breaker family. ## What it does not do — no control wire tap The TC1.4 terminal is a straight power connector with no integrated control wire tap. If your application requires a shunt trip, undervoltage release, or auxiliary contact connection at the same lug point, that wiring must be handled separately through the breaker's accessory slots — this terminal only terminates the main power conductor.","metaTitle":"Siemens SENTRON 3VA9243-0JD12 Wire Connector TC1.4, 6 AWG–35","metaDescription":"Siemens SENTRON 3VA9243-0JD12 TC1.4 circular conductor terminal for 3VA6 150/250 breakers.
