The Siemens SENTRON 3VA9233-0JG11 is a TA1.3 circular conductor terminal with an integrated control-wire voltage tap-off, sold as a pack of three units. It's an accessory designed specifically for the 3VA52 250 molded-case circuit breaker frame, letting you pull a control voltage off the line side without adding a separate tap block. Stripped length is 0.7 in — consistent across all conductor types, so the wireman doesn't need to adjust strip length when switching between solid and stranded.
This terminal mounts directly onto the 3VA52 250 breaker's line-side studs. The voltage tap-off means you can feed a control transformer or a shunt trip without running a separate conductor back to the bus — saves a terminal block position and one wire per phase. Because it's a circular conductor terminal, it's designed for the ring-tongue or fork-tongue lugs common on breaker line studs. The 14 AWG minimum ensures it works with standard control-circuit wiring; the 1/0 AWG maximum covers feeder-size conductors up to 50 mm².
