The Schneider Electric WATSN60/4AA is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It enables reliable switching between two independent power sources — such as the main utility supply and a backup generator — to maintain continuous power to critical loads during supply interruptions.
