 |  Re: Contactors : and how they work Yes Luke, this is done as well. I have used large contactors where there are fixed terminals for the neutral in and out, or an additional set of contacts for the neutral The contactor you have shown is 3 pole, so could be used for three phase (L1, L2 and L3) or single phase using two of the three contacts to switch line and neutral - i dont know if you are aware, but a lot of industrial three phase systems (particularly those supplying motors) dont use the neutral anyway! |

 | Re: Contactors : and how they work what about contactors with a2 at the top and a2 at the bottom of the contactor, are they linked in some way, so it doesn't matter which one you put the neutral in?? |
