Frequently asked questions
What wire sizes does 3VA9133-0JC12 accept?
It accepts stranded copper and aluminum cable from 4 AWG minimum to 300 kcmil maximum (-). Finely stranded copper also covers the same 4 AWG to 300 kcmil range. Torque spec is 252 lb-in for both stranded and finely stranded conductors. Strip length is 1.2 in.
What does the control wire voltage tap-off do on this terminal?
The TA2.1 terminal includes a control wire voltage tap-off that lets you derive a control voltage directly from the breaker line-side connection. This eliminates the need for a separate tap splice or an additional terminal block when feeding a control transformer or auxiliary circuit.
