Temperature switch for fan

[shridmaster]

I've never worked with mains AC so I wanted to get a sanity check here.

I have a heat exchanger used to cool down an air compressor. This is switched on by a temperature switch, a TS2-010 from Dwyer. Attached are pictures of the wiring diagram, fan motor, and temperature switch datasheet.

My thinking is that when the switch shuts off, the inductive load will cause an arc across the output and fry the contacts and create back emf into the grid. Am I way off? Is the drawing okay as is or do I need to add some sort of protection?

Thanks in advance!

If you have not worked with AC then I suggest you talk to an Electrician. Maybe a mate or friend of the family so you get a good rate.

I think White is Neutral for Single Phase in the USA.

You should be switching your Active wire.

The Dywer TS2 relay contact is only rated for 5A Inductive and your motor plate says 5.2A so you will need an interposing relay or Solid State Relay that can handle the current.
