Kyongbo Electric Low Energy Ground Over Current Relay with Instantaneous Unit GCO-CI

Kyongbo Electric Low Energy Ground Over Current Relay with Instantaneous Unit GCO-CI

Operation and tripping method are the same as type GCO-C; this low-burden relay is suitable for ground fault protection, especially on solidly grounded neutral systems using BCTs.

Key features

  • Low burden for BCT use
  • Connect CT secondary to terminals 4 and 5; terminal 6 for testing only
  • ICS coil options: DC current 0.2/2.0 A, 0.5/2.0 A, 1.0 A; DC voltage 24/110/125 V; AC current 0.5/1.0/2.0 A; AC voltage 110/220 V
