Wiring diagram of three-phase voltage transfer switch"

When wiring, you can wire according to the principle terminal number. There is a wiring formula: 1-3, 4-7, 6-8 seals (pre-wiring on the switch) 3, 8 connections in the middle, power supply sequence 7, 2, 5. Usually the indication is in the middle.The current of this circuit is very small, and the mechanical strength of the wire and fuse should be mainly considered. Therefore, the wire can be selected with an insulated copper wire of not less than 1.5mm2, the rated current of the melt should not exceed 5A, and the rated current of the fuse should not be less than the rated current of the melt.
