Fuse information
The values in tables are based on max ambient temperature of +50 ºC.
Fuse sizes can differ in the same chassis. Fuses can be chosen according to the biggest current
rating of the chassis to minimize fuse variants. Make sure that the I
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 < 250 amps (size 1
fuse), current > 250 amps (size 3 fuse).
The aR fuses are thermally rated into switch fuse in 50 degree ambient temperature.
