GKRC-02F Phase sequence relay

The ‌GKRC-02F Phase Sequence Relay‌ is an advanced protection device designed to secure three-phase electrical systems by monitoring phase sequence, phase loss, and voltage imbalance. Ideal for industrial motors, HVAC equipment, pumps, and renewable energy installations, it prevents equipment damage and operational disruptions caused by incorrect phase rotation, voltage asymmetry, or power supply irregularities.

Featuring a ‌broad voltage range (100-500V AC)‌ and ultra-fast response time (<50ms), the GKRC-02F detects phase reversal, single-phasing, and voltage imbalances (up to 30%) with precision. Its ‌IP65-rated, flame-retardant housing‌ ensures resilience in harsh environments, resisting dust, moisture, and extreme temperatures from ‌-25°C to +70°C‌. The relay integrates SPDT contacts (‌10A @ 250V AC‌) for flexible control of alarms, shutdown systems, or automated corrections. Enhanced ‌LED indicators‌ provide instant visual feedback for phase status, power supply, and fault alerts, streamlining diagnostics and maintenance.

Compliant with ‌IEC 60947-5-1, UL 508, and CE standards‌, the GKRC-02F supports DIN-rail mounting for quick installation. Adjustable sensitivity settings and a manual/auto-reset function enable customization to diverse system requirements. Widely used in manufacturing, data centers, solar/wind farms, and building automation, it ensures operational safety, minimizes downtime, and extends equipment lifespan through robust, energy-efficient performance.
