Hi,
I think Electronics is an update version of Electrical.For example we used tube light they need time to on and was not comfortable with voltage.Sometimes they would fused but now here we use electronics device so they have a voltage range and take no time to on and less affected by voltage.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
