Not to mention that the themal overload in the switch has no idea at

Sorry Charlie, only the best get to be StarKist.
The motor and overload are in series and see
exactly the same current.
BTW, at least 95% of all 3 phase motors are protected
by an overload relay that is art of the magnetic motor
starter used to control the motor.

An overload relay and thermal protection are two different things -
and this is a single phase motor
