    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
    Sensors
    • 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
