Good day,

I'm looking for heavy-duty DC contactors... I need them to be able to run under 220-250 Volts contact voltage and 220 Volts of control voltage. They should be able to handle 650 - 750 Amperes.

I've been searching for a few days, and I've contacted quite a few companies. Of them, Albright was the one that cared most for my demand, however they said my needs were beyond their current production range.

I'd very much like to learn where I can get DC Contacts with such specifications.

Thanks in advance,
Onur
