      Product Cross-Reference


      The GC-200 Ground-fault relay system protects a grounded distribution system from low level arcing ground faults. The system includes the GC-200 relay, a sensor (current transformer), and optional GC DSP display, and is used with a bolted pressure switch or circuit breaker to open a circuit upon detection of a ground fault.

      GC-200 Relay Features
      • Five models with sensitivities suitable for main, feeder, or branch circuits
      • Ten adjustable pickup settings for each model
      • Small, non-metallic enclosure mounts on DIN rail
      • 10 A and 5 A output contacts for trip and alarm
      • Zone-selective interlocking (ZSI) to optimize coordinated systems
      • I2t inverse time characteristics
      GC DSP Display (Optional)
      • Real-time display of ground-fault values
      • Recalls ground-fault at last trip or at maximum since reset
      • Allows remote testing or resetting of the relay for flexibility
      • LCD back-lit display for easy reading
      • Surface mounts over panel meter cutout
      • Fine adjust pickup settings
      • Zero sequence sensing current transformer for all phases and neutral
      • Several sizes of toroids and rectangular CTs
      • Many are split-core or open frame for ease of installation
