The Siemens SENTRON 3VA9674-0JB32 is a TA3.2 circular conductor terminal — an internal wire connector accessory that takes three cables per unit, sold as a pack of four. It fits 3VA55, 3VA65, and 3VA66 breaker frames. The terminal accepts stranded copper or aluminum from 4/0 AWG up to 400 kcmil, and finely stranded copper in the same range. Stranded 120–185 mm² terminates at 25.4 Nm; finely stranded 120 mm² also at 25.4 Nm. Strip length is 1.0 in. That torque spec is the one the panel builder needs to hit — no guessing. This is a pure wire connector accessory — no control wire tap. It's the termination point inside the breaker enclosure, not an external lug. The key fit question is whether the frame is a 3VA55, 3VA65, or 3VA66.
For a procurement buyer filling a BOM line, this part is specified into the 3VA55/3VA65/3VA66 panel design.
Integration note for the panel builder
Torque to 25.4 Nm on the stranded sizes. Strip 1.0 in of insulation. No control wire tap means no auxiliary connection through this block — that goes on the breaker's accessory slots separately.
