Technical Manual
All IEC and ANSI time delayed characteristics are available.
The directional function is voltage polarized, current polarized or dual polarized.
EF4PTOC can be set directional or non-directional independently for each of the
steps.
A second harmonic blocking can be set individually for each step.
