High Amp contactor selection 3

[Ali-rashid]

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.

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

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.

ABB's range of really big LV contactors is the R-Line:

Schneider also have some big stuff in their 'TeSys B' range

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.

Ah, yes, I forgot about Bar Contactors.
