If the measured value is higher than the upper limit (> or >>) or lower than
the lower limit (< or <<), the device reacts in accordance with the Behavior
parameter.

You can set the following parameters for each limit value:
▪ Relative/absolute limit value
▪ Limit value [A] or [kA]: Absolute limit value
▪ Limit value [%]: Limit value relative to rated current of current transformer
▪ Hysteresis limit value
▪ Delay time limit value
▪ Behavior limit value
