The 3VA9254-0JC13: A key feature is the integrated control wire voltage tap-off. That means you can pick off a smaller-gauge control signal or auxiliary power directly at the breaker lug — no separate tap block needed inside the panel. Saves a DIN-rail position and one wiring step during build-out.
The terminal also accepts finely stranded conductors in the same 2 AWG to 350 kcmil range, same torque. If you are terminating flexible cable (e.g., for a withdrawable unit that gets racked in and out), the fine-strand rating means you do not need a ferrule — the clamp is designed to grip the bundle directly.
The 3VA9254-0JC13 carries an active lifecycle status from Siemens. That means it is current-production, not a phase-out or last-time-buy item. No successor part number exists because none is needed — this is the terminal you order for a new 3VA1 250 build or a panel retrofit that uses that breaker frame.
This is not a DIN-rail mount component — it is a lug terminal that bolts onto the 3VA1 250 breaker's line/load studs. The package is 4 units, so you get enough for a 3-pole breaker plus one spare, or for a 4-pole configuration. Verify the stud pattern on your specific 3VA1 variant (plug-in vs. withdrawable) before ordering; the TA2.2 is designed for that frame, but the mounting hole spacing differs between fixed and withdrawable versions.
