Time Delays

The time delays ton1 and ton2 delay the activation of the alarm and pre-alarm.

If the earth-leakage current increases above the alarm threshold value >I2, the alarm is activated after the time delay tan = tae + ton, where

  • tae: relay operating time (For more details on operating time, refer section Technical Characteristics).
  • ton: time delay set

NOTE: If the alarm threshold >I2 is set to 30 mA (protection of persons), the time delay ton2 is automatically and invariably set to 0 s.
