37KW motor. Star delta start. What size of copper wire should be chosen? What size of contactor, circuit breaker, thermal relay? 25 flat wire. 16 flat is too small? Is it a 100A contactor and circuit breaker? Is it a 70A thermal relay? I'm not sure

The 16 level line is just right. I've done too much. The fan is overloaded
The following Chint models
Cjx2-6511 contactor (about 150 one) three
Dz20-100a (100 yuan) each
Nr2-93 48-65a thermal relay (60 yuan) is inserted under the angle contactor (there is no current when starting, and there is current behind the angle)
