The Schneider Electric WATSNB‑400/400 3P is a dual power transfer switch designed for switching a load between two independent AC power sources (such as utility mains and standby generator) in a three‑phase electrical system. It allows the electrical load to be transferred smoothly and safely between two supplies, ensuring continuity of service and protecting equipment. This 3‑pole version switches only the three phase conductors (without neutral) and is suitable for systems where neutral switching isn’t required. Typical installations include industrial panels, commercial power distribution boards, and backup power systems.

The WATSNB‑630/630‑3P is a dual power automatic transfer switch designed for three-phase power distribution systems.

The switch supports both automatic and manual mode, with auxiliary contacts for remote status indication and integration into control or monitoring systems.

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.

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.

The Schneider Electric WATSNB‑160/100‑4P series are dual power automatic transfer switches designed for three‑phase low‑voltage power distribution systems. They are used to automatically or manually transfer a three‑phase load between two independent AC power sources (for example, utility/main and generator). These devices ensure continuity of electrical supply for critical loads by detecting a loss or return of the main supply and switching to the alternate source accordingly. The 4‑pole configuration switches all three phase conductors and the neutral for full isolation and safety. Variants with suffixes like 4CBR‑F include auxiliary/feedback contacts and additional safety control interfaces for remote indication and integration with automation systems.
