Recommended rated current: 32 A;
number of poles: 2
Knife fuse  When the rated AC voltage on the
switch low-voltage side of the box-type
(solution 1) transformer is less than or equal to
500 V, the rated voltage of the knife
fuse switch should be greater than or
equal to 600 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 of the knife fuse switch
should be greater than or equal to
800 V.
 Recommended rated current of the
fuse: 32 A; rated current of the knife
fuse switch box ≥ 32 A; number of
poles: 3 (3 fuses for each knife fuse
switch box)
MCCB  When the rated AC voltage on the
(solution 2) low-voltage side of the box-type
transformer is less than or equal to
500 V, the rated voltage of the
molded case circuit breaker (MCCB)
should be greater than or equal to
600 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 of the MCCB should be
greater than or equal to 800 V.
