🔹 WATSN Remote Transfer Switch – NR01004 (100A, 4 Pole, Remote Operated Changeover Switch)
The WATSN NR01004 Remote Transfer Switch (RTSE) is a reliable remote-operated changeover switch designed for controlled transfer of electrical loads between two independent power sources. It is widely used in commercial, industrial, and critical power applications where source transfer is managed remotely through PLCs, generator controllers, SCADA systems, or Building Management Systems (BMS).
Featuring a 100A rated current and 4-pole configuration, the NR01004 provides complete switching of three phases and neutral, ensuring enhanced electrical isolation and system safety. Built on the proven Class PC transfer switch platform, it offers dependable switching performance, long operational life, and secure power source management.
The switch incorporates a three-position mechanism (Source I – OFF – Source II), allowing safe transfer operations and maintenance isolation. Its compact design and robust construction make it suitable for generator backup systems, industrial control panels, and critical power distribution networks.
