The Schneider Electric WATSG is a heavy-duty, 4-pole (3P+N), 250A manual changeover switch. Designed for robust performance in critical power distribution systems, it enables safe and reliable manual transfer of electrical loads between two independent three-phase AC power sources (e.g., Utility Main and Backup Generator).
