Hi. I am working with DC voltages in the range of 500V-1000V and so the DC isolator switches I use under the guidelines I am following need to be double pole ie there needs to be two breaks in the switch gear for every wire coming in. What I want to find out as I have been looking at various DC isolator switches is what is the difference or pros/cons between DC isolator switches which have 2 breaks per cable in series and in parallel
So in series the break per cable is
And in parallel each cable forks and there are then two poles
Is one more reliable than the other as far as arcing is concerned, and if so why??
Thanks
So in series the break per cable is
