K...so I use 4 of these http://ixdev.ixys.com/DataSheet/DSEP2x31-12A.pdf for getting together 2 bridges for one channel, solved one problem.
I also have http://ixdev.ixys.com/DataSheet/DSS2x101-015A.pdf but not enough for getting together 4 bridges and I was wondering if they are better to use between earth and ground? (if Vrrm is not too low)

use 10R NTC between chassis and GND

save those biggies for something else

5A NTC is OK

whatever you choose .......

diodes or NTC will work only to save your a$$ in case of major malfunction
