The LA9G3RA is a switch module kit from the Schneider TeSys range — three individual modules delivered as a set, each rated for 3-pole bolted connection. It mounts on a TeSys contactor frame to provide a separate switching function (e.g., for isolation or auxiliary loading). The kit is ordered as one line item and covers all three poles.
The AC-1 rating (440 A) covers resistive or lightly inductive loads — heating, lighting, distribution. The AC-3 rating (330 A at ≤440 V, 40 °C ambients) covers motor starting and disconnecting; this is the number you use for a standard squirrel-cage motor. The module is pollution degree 3 rated, so it tolerates the typical industrial panel environment without conformal coating. Bolted terminals accept standard lugs; no special tooling needed.
