The Schneider LA9G3SA is a TeSys switch module supplied as a set of three, rated 700 A in AC-1 duty and 500 A in AC-3 up to 440 V at 104 °F (40 °C).
This is a bolted-connection module—no spring clamps, no wire cages. It mounts on a TeSys disconnect or switch base and carries pollution degree 3 rating, meaning it holds up in the kind of greasy, dusty panel you find near conveyors or pumps. Operating range from -13 to 140 °F covers most plant floors; storage down to -76 °F if you're sitting spares in a unheated warehouse. Altitude rating to 3000 m without derating covers high-lift plants or mountain sites.
