WATSNB-100/25.3CBR_Schenider_PRODUCT_吉林易择科技技术发展有限公司

The Schneider Electric WATSNB‑100/25 .3CBR is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It provides reliable and automatic switching of electrical load between two independent AC power sources — such as utility mains and a standby generator — to ensure continuous power supply for critical equipment. The switch continuously monitors the voltage and availability of both sources and automatically transfers the load when the primary source fails or returns.
