What primary settings do you want to program into the relay, and what is your CT ratio?

For MiCOM P120, as all so-said P20 range, setting is made related to In ( e.g. 0.1 In for 10% threshold).
For information, MiCOM P120 ( as well as other MiCOM) belongs now to Schneider Electric.

My CT ratio is 150/5
