1) For the supply circuit 6 A delayed, for MCB use C characteristics.
Calculated power loss at operational current (Iop) without by-pass.
2)
Ptot = 3 x Iop + VA value
Example: PSS 60/105 running at 52A
Ptot = 3 x 52 + 10 = 166W
Max fuse rating independent if In-Line or Inside Delta connection. In Inside Delta connections of PSS, the fuses can be placed outside of the delta.
