2 Fuse ● When the rated AC voltage on
the low-voltage side of the box-
type transformer is less than or
equal to 500 V, the rated voltage
should be greater than or equal
to 500 V; when the rated AC
voltage on the low-voltage side
of the box-type transformer is
greater than 500 V and less than
or equal to 800 V, the rated
voltage should be greater than
or equal to 800 V
● When the rated AC voltage on
the low-voltage side of the box-
type transformer is less than or
equal to 500 V, the rated current
should be greater than or equal
to 6 A; when the rated AC
voltage on the low-voltage side
of the box-type transformer is
greater than 500 V and less than
or equal to 800 V, the rated
current should be greater than or
equal to 32 A
