12v 4 Pole NC Contactor

[uksparks]

Hi,

where re can I get a 12v 4 Pole NC contactor capable of day 50A or more...?

i can't seem to find one, the alternative is can I pull a contactor on with 230v that's closing or opening 12v circuits? Seems wrong to mix ELV with LV.

I'll keep looking online.

what I'm trying to do is make a setup that will when 230v is present it opens the contactor to prevent all the neutrals on the batteries being connected.

quite common to have a contactor with elv coil switching a 240V load, so can't see a problem with you using it arse about face like you describe.

Can't use a series of 50a relays?

I suppose so

That would be a 230v contactor, not a 12v one.

As Marvo says you get 230v contactor with your required coil voltage. The 230v is just it's maximum voltage rating, you can use less. Just the coil voltage is specific.

Neutrals on batteries do not exist


Are you talking about AC or DC

I think your ac/dc question is dumber then getting neutral and negative mixed up.
