Single-phase network with neutral (1PH + N)
The 3KC4 and 3KC8 transfer switching equipment can be used in a single-phase network
comprising one phase and a neutral conductor. Since there is no 2-pole design available for
the transfer switching equipment, the 3KC4 and 3KC8 transfer switching equipment in 3-pole
design is the best choice.
