Schneider Electric Dual Power Transfer Switch – Model WATSNB‑400/400 4CBR The WATSNB‑400/400 4CBR is a manual or automatic dual power changeover (transfer) switch / dual input selector switch designed for switching a load between two independent power sources (such as utility and generator). It is used in electrical distribution systems to ensure continuity of power by selecting between two available supplies. The “4CBR” suffix indicates a 4‑pole configuration with built‑in control and safety contacts for interlocking and signaling, conforming to typical industrial dual power switch conventions.

The WATSNB-630/630 .4CBR is a compact, modular 4-pole circuit breaker from Schneider Electric's Acti 9 series. It combines the functions of a miniature circuit breaker (MCB) for overload and short-circuit protection with advanced residual current protection using Current Balance Relay (CBR) technology. This device is specifically designed for applications requiring high immunity to nuisance tripping while providing protection against various types of residual currents, including smooth DC components.

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 4‑pole configuration switches all three phase conductors plus neutral for full load transfer and safety. The unit supports both automatic and manual changeover modes and includes auxiliary contacts for status feedback and system integration.

The Schneider Electric WATSNB‑63/4PCR is a dual power automatic transfer switch designed for three‑phase low‑voltage power distribution systems. It is used to automatically or manually transfer electrical load between two independent AC power sources (such as utility mains and a backup generator) to maintain continuity of supply for critical loads. The 4‑pole configuration switches all three phases plus neutral for complete isolation and safety. Auxiliary contacts are provided for remote status indication and integration with external control or monitoring systems.

The Schneider Electric WATSNB‑32/4PCR is a dual power automatic transfer switch designed for three‑phase low‑voltage power distribution systems. It provides reliable switching of electrical loads between two independent AC power sources (such as utility mains and a standby generator), ensuring continuity of supply for critical equipment and circuits. The 4‑pole construction switches all three phase conductors plus neutral, offering complete load isolation and enhanced safety. 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.
