What it is and where it lands
The SENTRON 3VA9113-0JJ12 is a TA2.1 circular conductor terminal — the wire connector that lands the incoming feeder on a 3VA1 100/160 frame molded-case breaker. It's the lug kit, plain and simple: three pieces per pack, sized for copper or aluminum stranded cable from 4 AWG up to 300 kcmil, and finely stranded copper in the same range.
