Hello,
you can calculate the current by ohm' law.
For the primary fuse use the mainvoltage in worst case (-5%).
According to the soft start circuit, the 500 VA transformer needs I = P / U = 500 VA / 215 V = 2,32 A. Use 2,5 A very slow blow up or 3,15 A slow blow up Type.
The 60 VA transformer needs I = P/ U = 60 VA / 215 V = 0,28 A. Use herefor 0,315 A slow blow upType.
To be save in all events of failure you can additional use fuse on the secundary side of the transformers. These fuses must be normal blow up types.
I hope it will help
regards
Rainer
