Fuse information
The values in tables are based on max ambient temperature of +50 ºC.
Fuse sizes can differ in the same chassis. Make sure that the Isc of the supply transformer is high enough to
burn fuses fast enough.
Check the current rating of the fuse bases according to the input current of the drive.
The physical size of the fuse is chosen on the basis of the fuse current: Current > 400 amps (size 2 fuse or
smaller), current < 400 amps (size 3 fuse). The aR fuses are thermally rated into switch fuse in 50 degrees
ambient temperature.
