switch
Select either an MCCB or a knife fuse switch as the three-phase power switch. If you select an
⚫
MCCB, ensure that the let-through energy of the MCCB meets requirements. The breaking
capacity depends on the limited short-circuit current on the low voltage side of the box-type
transformer.
Models of the components inside the box-type transformer are specified by the box-type
⚫
transformer vendor.
