Fuse sizes, Bussman aR fuses
Fuse information
Max fuse ambient temperature +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).
