It looks like a Telemecanique LR9 F 5567

Welcome. My name is ***** ***** would be glad to assist.

I see that the other expert has opted out of the question, and wanted to see if you are still in need of assistance?

I noticed that the Square D LC1F150 is a basic contactor

And the Telemecanique LR9 F 5567 is a basic electronic overload.

Where is the soft start equipment associated with the controls?

What was the original motor on the equipment? Make and Model?

You may have originally had a Wye start/Delta run wound motor for the application which had 12 leads?

Let me know and we can continue,

Thanks

Expert:  AssuredElectrical replied 1 year ago.

Ok, very good.

Would be interested to know the conclusion if you had a minute to post?

Thanks either way.
