My circuit is a modifed version of one shown here:

Worth a look, as it also contains very useful info about safety and ratings.

I am glad you like it Adam, it has worked fine for 3 years.
I agree RS is expensive. I was in a rush, also I think I paid a fair bit less in 2011.
The contactor is perhaps over specced as well, so the end result could be achieved a lot cheaper with a bit of research and shopping around. The Santon switch should last a long time as it only carries the starting current and never switches under load, unless you attempt to reverse without stopping. This causes the contactor to safely drop out.
The new contactor and overload are mounted on a short piece of DIN rail.
The DIN rail is secured using the existing screws that were used to fix the original contactor.

My album is now working:

Hi Stephen,

I have just joined the forum.

Are you on the way to a solution or are you still looking?

I converted an industrial stand from 3 phase to single in 2011.

The Myford factory electrician told me I had to replace the Santon rotary switch with a rather expensive and ugly one from RS. This solution did not provide no voltage release.

I didn't want to change the external appearance of the front panel, so I did it by replacing the contactor. Worked our fairly inexpensive I think, doesn't load the Santon switch much and provides NVR.

I will add a wiring diagram if I can get "Albums" to work!
