For 3 phases compressor:

7.5kw compressor uses 4 square meters of wires, the breaker/air switch uses 32A. 11kw compressor uses 6 square meters of wires, the circuit breaker uses 56A. 15kw compressor uses 8 square meters of wires, the circuit breaker uses 60A. 22kw compressor uses 10 square meters of wires, the circuit breaker uses 100A. 37kw compressor uses 20 square meters of wires, the circuit breaker uses 150A.

For the single phase compressor:

Current (A) is the power(kw)*4.5, for example, 7.5kw single phase compressor needs to use 6 square meters of wires and 34A circuit breaker.
