    6 F 2 S 0 8 2 8 2.3 Phase Fault Overcurrent Protection GRL150 provides three phase overcurrent protection with four independent overcurrent thresholds OC1 to OC4. The first threshold OC1 may be set for inverse time or definite time operation.
  • Page 22 6 F 2 S 0 8 2 8 In addition to the above nine curve types, the OC1 can provide a user configurable IDMT curve. If required, set the scheme switch [M∗∗∗] to “CON” and set the curve defining constants k, a, c, kr and b.

Definite time reset The definite time resetting characteristic is applied to the IEC/IEEE/US operating characteristics. If definite time resetting is selected, and the delay period is set to instantaneous, then no intentional delay is added.
