The two power supplies can serve as backup for each other.
Component selection: D210-100/3 is selected for low-voltage circuit breakers QFi and QFz (determined by load capacity). The combined switches
SAi and SA2 are of type H210-10/2. The fuse is selected as RLl-15/5A. Contactors KMi and KM2 use CJlo-
100/380V (determined by load capacity). The indicator light uses XD3-220/15V, 2V. A or other models. The selection of
the above components can also be used as a reference for each circuit introduced below .
