The 3VA9871-0JJ63: This terminal bolts onto the line or load side of a 3-pole SENTRON molded-case breaker (3VA58/59/68/69). It's a panel-shop item: you land the incoming feeder cables into this terminal block rather than directly onto the breaker lugs, which simplifies cable management and re-termination during commissioning or retrofit. The circular conductor design accepts both copper and aluminum stranded — no need for a separate bimetal adapter.
