  • Page 7: General Information

    The following information concerns the use of the Actual values and the Setpoints. OVERCURRENT PROTECTION IPR-D continuously checks the ground current in the line by means of its CT and activates an alarm and/or the circuit breaker trip when a value exceeds the set level (called Pickup level): 1.
  • Page 8 For the 3 possible curve types and their shapes see: Appendix A REMARK: when selecting the curve for the circuit breaker trip, make sure the max. input current to IPR-D does not exceed 100 A for more than 1 second ⇒ the wrong combination of time and current could damage the unit and consequently provoke the loss of protection.
