Capacitor Fusing / Cable Size
Fuses and Cable Sizes for PFC Capacitors
Fuses and cross−section of conductors
PFC correction capacitors should be provided with fuses with a slow breaking characteristic (gG).
Cross−section of conductors should be sized to at least 1,6 − 1,8 multiple of capacitor’s rated current (see table − recommended cross−sections of conductors and sizing of fuses).
Connection of capacitors should be performed only by Cu conductors based on the following table.
