High side fuse selection: 1. If the capacity is below 100KVA, the high-voltage side should be selected according to 2-3 times the rated current of the transformer. 2. For those with a capacity of 100KVA or more, the high-voltage side fuse should be selected according to 1.5-2 times the rated current of the transformer. ■Low-voltage side fuse selection The low-voltage side fuse of the transformer is selected according to the rated current of the transformer.
