High Amp contactor selection

High Amp contactor selection

(OP)
Hello
I am struggling in finding the proper contactor for my requirement. I have an application which needs a contactor that satisfies the below characteristics:
690 Volt
1200 kW
1200 Amp
please refer me to brands and models available in this range. please provide the exact model as I searched a lot among different brands and couldn't find the desired contactor.

RE: High Amp contactor selection

ABB and Eaton both have contactors in their standard product lines that can do that. The ABB contactors are AF models.

RE: High Amp contactor selection

As far as I am aware, there are only 3 manufacturers of contactors that size, because the demand is extremely low. ABB, Eaton (Klockner Moeller) and an Italian mfr named Ghisalba. The Ghisalba contactor is then brand-labeled by Siemens, Allen Bradley and several other smaller names all over the world. Schneider and GE (Agut) also make contactors that large, but apparently not for 690V.

I forgot all about Unelec, who I think have since passed into Mersen's ownership: a range of very heavy duty contactors for generator field switching and similar applications. The largest AC variant is rated 1100V / 7500A. http://ep-uk.mersen.com/fileadmin/catalog/Literatu...

Ah, yes, I forgot about Bar Contactors.
