IN1>3 2H Blocking
Disabled
Enabled / Disabled
This setting determines the enabling/disabling of blocking third stage measured earth fault element due to presence of inrush current.
If IN1>3 Blocking and 2nd Harmonic settings are enabled, then (IN1>3) trip command will be blocked in case 2nd harmonics content in
any phase is above the 2ndHarm Thresh. and fundamental current is below I> lift 2H setting . (Set in SYSTEM CONFIG Menu.)
