APPENDIX B: FUSE AND WIRE SIZING
FUSES
Branch circuit protection must be provided by the end
user and sized per national and local electric codes.
The following tables provide fuse recommendations
for short circuit protection on the drive's input power.
The rated fuse currents given in the tables are the
maximums for the mentioned fuse types. If smaller
fuse ratings are used, check that the fuse Arms current
rating is larger than the input current.
Check that the operating time of the fuse is below
0.5 seconds. The operating time depends on the
fuse type, the supply network impedance as well as
the cross-sectional area, material and length of the
supply cable. In case the 0.5 seconds operating time
is exceeded with the gG or T fuses, ultra rapid (aR)
fuses will in most cases reduce the operating time to
an acceptable level.
