It's a field-installed accessory, not a standalone component; you add it to the 3VA6 150/250 frame when the feed cable is too big for the breaker's direct connection. ## Wire range and what it means on the van It also handles aluminum cable in the same 2 AWG to 350 kcmil range, which is useful when you're landing older Al feeder or doing a copper-saver install. ## Control wire tap-off — why you'd spec this over a plain lug The key differentiator is the integrated control wire voltage tap-off. A small secondary terminal lets you pick up line voltage for a control transformer, a shunt trip, or an auxiliary relay without adding a separate tap block or splicing into the main conductor. That saves a DIN rail position and a wiring step in the panel.","metaTitle":"Siemens SENTRON 3VA9243-0JC13 Wire Connector, TA2.2 350 kcmi","metaDescription":"Siemens SENTRON 3VA9243-0JC13 wire connector TA2.2, 2 AWG to 350 kcmil, with control wire voltage tap-off.
