 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! |
