The Siemens SENTRON 3VA9233-0JA11 is a box terminal kit — three TS1.2 terminals, designed as an accessory for the 3VA5 250 molded-case breaker family. If you're wiring a 3VA5 250 panel and need the factory terminal set, this is the order code.
These terminals mount directly into the 3VA5 250 breaker's load-side lugs. No adapter plate, no drilling. The TS1.2 design uses a box-style clamp — the conductor seats inside a square tunnel, not under a setscrew, so stranded wire doesn't birdcage when you torque it. Three units per pack covers a 3-pole breaker.
