感谢以上各位 ：）but challenging to find the right current rating

ok, first i need an NC;

also it has to be able to sustain 175a continuous current.

i am unable to find one.  anyone knows where to get it?

 

if i can't get one, i would have to settle with a large 200a NO relay and a small NC relay on the coil line.  it'll be a workaround but i really like to have a single NC directly.  appreciate any leads.
