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.
