The Schneider Electric WATSNB‑100/32.4CBR is a dual power automatic transfer switch designed for low‑voltage three‑phase 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 supply for critical loads. The 4‑pole configuration switches all three phase conductors plus neutral, ensuring full isolation and improved safety. Auxiliary contacts provide remote status indication and integration with control or monitoring systems. The interlocking design prevents both supplies from feeding the load simultaneously, enhancing operational safety.
