The Schneider Electric WATSNB‑160/100‑4P is a dual power automatic transfer switch designed for three‑phase, low‑voltage power distribution systems. It automatically manages the transfer of electrical load between two independent AC power sources (for example, utility mains and a standby generator) to maintain continuous power availability for critical loads. The 4‑pole configuration switches all three phase conductors plus neutral, enabling full electrical isolation and enhanced safety. The switch supports automatic, manual, and interlocked operation modes and incorporates auxiliary contacts for remote monitoring and integration with control systems.
