The Schneider Electric WATSGA-100/4R is a 4-pole (3P+N), 100A manual changeover switch designed for safe and reliable manual transfer between two independent three-phase AC power sources. It provides a simple, robust, and cost-effective solution for applications where backup power is available but automatic transfer is not required.
