Kakato,

You will find all the information you need at www.danfoss.com.

If you search their site for "TL3" then you will be able to download the full spec, the TL3B is old, I believe, but the data you are after will be the same for the modern ones (-G / -F).

Happy hunting,

I think that the TL3B is actually a reference for the start relay or the Klixon from what I could find on their site, none of it was in English which didn't help me much ;)

N=f x 60/2P

N number of turns
f frequency of power supply
P number of poles

Then you need to ad slip in that calculation
