What this terminal is and what it connects
The Siemens 3VA9214-0JC13 is a SENTRON TA2.2 circular conductor terminal — a wire connector sized for 50…240 mm² large conductors with an integrated control wire voltage tap-off. It ships as a set of 4 units and is designed as an accessory for the 3VA1 250 molded-case circuit breaker family. Stripped length is 1.2 in, which matches standard lug-barrel depths for this class of connector. The control wire tap-off lets you pick up a voltage signal directly at the breaker load terminal without a separate tap block — useful for panel layouts where every DIN-rail position counts.
No second-source cross-reference exists — this is the specific TA2.2 terminal for the 3VA1 250 frame.
The control wire voltage tap-off is a secondary terminal on the same body; it takes a smaller-gauge wire for signal or auxiliary power. In a panel build, this eliminates a separate terminal block for the breaker's under-voltage release or shunt trip supply.
