The 3VA9223-0JC13: A key differentiator: this connector includes a control wire voltage tap-off, so you can pick off line-side voltage for auxiliary circuits without a separate terminal block. That saves a DIN-rail position and one wiring step in the panel.
Integration note
Designed for direct mounting on the 3VA2 breaker's line or load terminals — no adapter plate needed. The control wire tap is a screw-type takeoff point integrated into the connector body, so the tap wire runs to the same torque spec as the main conductor.
