It is designed as an accessory for the 3VA6 150/250 molded-case circuit breaker frame. The terminal accepts solid, stranded, and finely stranded copper from 14 AWG minimum up to 1/0 AWG maximum across all three conductor types. That range covers most feeder and branch-circuit taps on the 3VA6 frame. ## Panel Integration This is a lug-style terminal that bolts onto the 3VA6 150/250 breaker line and load side. No DIN-rail mount — it lands on the breaker studs, so the panel fill factor is driven by the breaker footprint, not the terminal itself. The control wire tap-off saves a separate terminal block for a shunt trip or auxiliary contact feed.","metaTitle":"Siemens 3VA9143-0JK11 SENTRON Wire Connector TC1.3, 14 AWG–1","metaDescription":"Siemens 3VA9143-0JK11 SENTRON circular conductor terminal TC1.3 for 3VA6 150/250.
