The Schneider Electric WATSNB‑100/63 .3CBR is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It provides automatic and manual load transfer between two independent AC power sources (such as utility mains and a standby generator), ensuring continuity of supply for critical loads. The device continuously monitors both sources and initiates transfer when a preferred source fails or is restored.
