The Schneider Electric WATSGA320/4 is a three-phase, 4-pole (3P+N) manual changeover switch with a rated current of 320A. Designed for reliable power source transfer in low-voltage distribution systems, it allows an operator to manually select between two independent AC power supplies (e.g., Utility and Generator) while ensuring complete electrical isolation.
