Can someone give me a link that shows the wiring diagram to wire three 4-pole lighting contactors in parallel (to control 12 lighting circuits.)

 
Elekk,

IF you are merely switchitn lives, run the lives through the load connections.

IF you are using a "normal" light switch to control the contactors, you don't need a retain circuit, thus wire all the A2's in parallel to N.

Wire the A1's in parallel, with the light switch in series with the supply to one of them

HTH

;)

ignore the aux contact :Blushing

thanks button bottom right :coffee :D

 
Thanks for the information Lee. One more question about the circuit that you posted above; Can this circuit be used for "four" 3-phase lighting circuits, or "twelve" 1-phase lighting circuits, or both?

 
Elekk,

This would depend on the rating of the contactor.

IF the load contacts were 4 off full load rating then you could use them for 12 lighting circuits, if not then you could only use the 4th contact to its rated current.

4 (load) pole contactors are freely available, and these may also have another aux contact.

 
My example was using 3 pole contactors . So yes 4 3ph supplies or 12 1ph
