The 3VA9243-0JC22: Mounts directly into the 3VA6 150/250 breaker line terminals — three units per breaker cover the line-side connection. The circular conductor terminal design accepts both copper and aluminum conductors without special preparation beyond stripping to the listed length. The integrated control wire tap lets you pick off a smaller-gauge control voltage without a separate terminal block, saving a DIN-rail position in the panel.
The 3VA9243-0JC22 carries an active lifecycle status, meaning it remains in Siemens' current production portfolio. No last-time-buy or phase-out notice is recorded.
