I've been following Clough42's videos on sorting out a VFD with a lathe and trying to figure out what I need, electrically, before and after the VFD.
It looks like (from the link below) that he's using:
The contactor seems very much like what we would call an NVR in the UK - should I bother wiring in either an NVR or a contactor, or could I just go with the 13A fused plug and switch to supply the VFD (with the MCB behind it)?
I do plan to have low-voltage switches for forward/stop/reverse and frequency on a pot. I'm thinking I can power the whole lot either directly from a switched 13A BS1363 socket or maybe put an NVR in series.
Thoughts?

- MCB
- Magnetic contactor
- AC reactor (he reckons this ain't needed in a home shop)
- Fast acting fuse
- Input noise filter
- VFD
- Output noise filter
- Motor
