Question about RTO Telemecanique Gv2 Ls22 Magnetic Circuit Breaker
I don't know why your question is bound to this special breaker.
If your question is common, the wye/delta is a way to reduce the starting current of a large three phase asinchronous motor.
When a three phase motor is first connected in wye (star), the starting (peak) current is about 3 times less than this in delta. When already in motion the electromotive force will make the peak current when turned in delta much less, than that with a stopped motor.
