Notes
Inrush
VA refers to short time contactor inrush current applied
to a Transformer whilst holding 95% of output voltage.
Primary fusing as recommended, taking into consideration
transformer's Inrush/Energizing current. Fuses should
be Motor Rated
Primary fusing does not give over current protection,
only
Short Circuit Protection
Secondary fusing should be calculated using the formula:-
Transformer
Rating VA = I (Amps)
Secondary volts = V I
= Rating of fuse protection
