We talked about industrial SCRs that I have. My SCRs have 2 trigger wires instead of 1. I think the #20 red wire and 120 amp red wire are connected but not sure. I have 6 of these I need to test to see if they are good. We talked about these years ago now I have a project for them. Also need to know if SCRs are npn or pnp devices.
SCR numbers 71RC12 and 9051AR rated 120a and maybe 600v
