Dual Power Isolation Switch Manual Transfer Switch SF219G 40A 400V Modular Chang

The rail-mounted dual power conversion isolation switch has four functions of on, off, conversion and isolation. It can be freely switched on and off between two loads carried by a group of lines, or on two power sources.
The position of the incoming and outgoing wires can be adjusted according to actual needs (the upper and lower out are not necessarily required, when used for dual power switching, the lower in and upper out must be used.)
