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.","metaTitle":"Siemens 3VA9871-0JJ63 SENTRON TA7.4 Wire Connector, 600 kcmi","metaDescription":"Siemens SENTRON TA7.4 circular conductor terminal for 6 cables 300–600 kcmil copper/aluminum.
