Is it possible to connect a three-phase electric motor without a starter?

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 -https://my.electricianexp.com/en/kak-podklyuchit-trehfaznyj-elektrodvigatel.html. 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.
