Product details

The Siemens SENTRON 3VA9243-0JD12 is a TC1.4 circular conductor terminal — a lug-style wire connector designed specifically for the 3VA6 150/250 frame molded case circuit breakers. It accepts stranded copper conductors from 6 AWG up to 350 kcmil, making it the correct termination accessory when landing larger feeder or distribution cables on that breaker family.

What it does not do — no control wire tap

The TC1.4 terminal is a straight power connector with no integrated control wire tap. If your application requires a shunt trip, undervoltage release, or auxiliary contact connection at the same lug point, that wiring must be handled separately through the breaker's accessory slots — this terminal only terminates the main power conductor.

Frequently asked questions

What is the torque spec for 3VA9243-0JD12 on 350 kcmil stranded copper?

For conductors from 1 AWG through 350 kcmil, the terminal requires 275 lb-in of torque. For the smaller 6–2 AWG range, the spec is 140 lb-in. The stripped length is 0.8 in for all sizes.
