How to wire a contactor

Please I will like to ask a basic question about how to wire a Contactor.

I got this 4Pole contactor from EATON (Moeller (Eaton) Contactor modular 25-40 (Z-SCH230/25-40))

I have an AC load I want to use it to drive. Just to test if my contactor is working, I connected a 24V power supply to my A1 and A2 terminals of my Contactor.

I connected my 3 Phase AC to terminals 1 3 5 and I connected the load to the corresponding terminals 2 4 6.

The COntactor is a 4NO Contactor

Unfortunately I did not hear any switching so my load is not connected to the Supply after doing this.

My question is: Is it not possible to use a DC voltage source like 24 V supply to drive a contactor coil?

What could be wrong?

Thanks.

Please find the image below

 

Check the specs on the coil, I can't see the information on the side of the contactor in the picture, but the coils are usually AC, and the code for the part has 230 in it, which leads me to guess this is what it is. If that is the case, you may have to drive the coil from a relay if you want low voltage dc control.

Oh thanks so much, that is correct. The specicification on the relay says 230V ac
Now I will rewire it like this.

I will connect A1 termainal to the AC Main Live
And I will allow the second relay to be driven by a switch and a 24V DC supply.
I will make the small relay a NO and connect one of the legs of the output to the A1 of the contactor and the second to the Neutral of the AC supply.
The relay should close when the switch contact is closed and the 24v drives the coil of the small relay. When this happen the Neutral and my A1 should be connected and hence my load.

Please is my analysis correct?

Should be wired up like this,
cheers,
Richard

Thank you very much. I will try it out tomorow

Is it not possible to just replace this contactor with one with a 24VDC coil?

Yes, you can, but a relay probably works out cheaper than having to buy another contactor, unless he can do an exchange,
cheers,
