I have a Furnas motor/starter on a piece of older equipment I bought. Probably 1970's or maybe even 60's. It is three phase but only has two overloads. The wiring diagram also shows it this way. The previous owner, a high school shop, added a separate box with another contactor. I have not puzzled out all the wiring but I think they added it to switch control voltage for the third phase which is not protected. But it does not add a third heater circuit.
Just wondering if any one has seen similar?
I will probably gut the wiring and the second contactor and switch to single phase. They also changed the switch and it's location so this may be part of that change.
