The Schneider Electric WATSNB‑100/40‑4CBR is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It automatically or manually transfers electrical load between two independent AC power sources — such as utility mains and a standby generator — to maintain continuous power for critical loads. The 4‑pole configuration switches all three phase conductors (L1, L2, L3) and the neutral (N), offering full isolation and safety. The switch continuously monitors the status of both sources and initiates a transfer when the primary source fails or is restored. Auxiliary contacts provide remote status indication and integration with building or generator control systems. A safety interlock prevents both incoming sources from being connected simultaneously, enhancing operational safety.
