Is it possible to connect a three-phase electric motor without a starter?
Good time! The question is, is it possible to connect a 3-phase ventilation motor without a start button directly to a 3-phase circuit breaker? Thank.

Yes, it is possible to connect directly to the circuit breaker and there is no problem, but note that the circuit breaker is not designed to operate as a circuit breaker. It is needed to protect the circuit from overload. If you often turn this engine on and off in this way, the machine will quickly fail.
Good afternoon, what is the “start button”? Three-phase electric motors are connected not through a button, but through contactors or magnetic starters, you can read about this in this article -
Thank you, I had in mind the magnetic starter, not so expressed because of unprofessionalism))).
