GKRC-02 Phase sequence relay

The ‌GKRC-02 Phase Sequence Relay‌ is a high-performance protection device engineered to ensure the safe and efficient operation of three-phase electrical systems. It monitors phase sequence, phase loss, and voltage imbalance, safeguarding motors, generators, pumps, and HVAC equipment from damage caused by incorrect phase rotation or power irregularities. Suitable for industrial, commercial, and renewable energy applications, it guarantees operational continuity by preventing costly downtime.

With a ‌wide input voltage range (100-500V AC)‌ and rapid response time (<80ms), the GKRC-02 detects phase reversal, single-phasing, and voltage asymmetry (up to 25% imbalance). Its ‌IP55-rated, flame-resistant housing‌ ensures durability in harsh environments, resisting dust, moisture, and temperature fluctuations from ‌-20°C to +60°C‌. The relay features SPDT contacts (‌10A @ 250V AC‌) for flexible integration into control circuits, alarms, or shutdown systems. Enhanced ‌LED indicators‌ provide real-time status feedback for phase sequence, power, and fault conditions, simplifying diagnostics and maintenance.
