WATSNA63/4_Schenider_PRODUCT_吉林易择科技技术发展有限公司

The Schneider Electric WATSNA63/4 is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It is intended to facilitate reliable and safe switching of electrical load between two independent AC power sources — for example, between utility mains and a standby generator or alternate supply — to ensure continuous operation of critical equipment. This switch continuously monitors both power sources and automatically initiates a transfer when a primary source fails or is restored. It helps prevent back‑feeding and maintains load continuity in industrial, commercial, or backup power applications.
