Panel integration — what it connects to
The 3VA9224-0JJ22: This is a line-side or load-side lug kit for 3VA2 breakers in the 100/160/250 frame. It comes as four units per package, which matches the typical three-pole breaker plus one spare or a three-pole plus neutral configuration. The TA2.3 designation means it's a two-cable terminal — each lug accepts two conductors from 25 mm² to 150 mm², useful for paralleling feeds or looping through to a downstream disconnect without an extra splice bar. Mounting is a direct bolt-on to the breaker's bus bar; no adapter plate or DIN-rail bracket needed.
