The Schneider Electric WATSNB‑100/100 .3CBR is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It provides automatic or manual transfer of electrical load between two independent AC power sources, such as utility mains and a standby generator, to maintain uninterrupted power to critical loads. The device continuously monitors both sources and initiates transfer when a source fails or returns to service.
