Answer / ram
See the full load Current,(It is written in the motor name
plate)
1st:set the fuse to be around 2*Full load current
2nd:Set the OLR to operate at 95% of FLC to get more
operating Life for your motor.
Note:Couple the motor to the load and see How many amps
draw and set it Higher the load by 5% and make sure the
Load current not grater than Motor Name plate current.
