What’s the difference between the branded TK Siemens soft start and the Siemens soft start? Can you swap the regular Siemens with the TK one?

I'm interested also. I heard a guy from Siemens once mention the existence of a "TK" version of the soft start logic board. Then the parts folks in my company acted like I was an imbecile when I ordered a logic board for a Siemens soft start a couple years ago and noted it was specifically for a TK. But I find it odd the guy from Siemens talked like it was different.

As far as I know though there is no real difference.

Waiting to see any good info here

Replace a Siemens order from none tk supplier on tac32 with no issues. Discrete wiring. Just copy settings and good to go.

I’ve never paid attention to where the starter or logic board came from.
