Functionality

The Instantaneous residual overcurrent protection EFPIOC has a low transient
overreach and short tripping times to allow the use for instantaneous earth-fault
protection, with the reach limited to less than the typical eighty percent of the line at
minimum source impedance. EFPIOC is configured to measure the residual current
from the three-phase current inputs and can be configured to measure the current from
a separate current input. EFPIOC can be blocked by activating the input BLOCK.
