This Earth Leakage Relay is designed to detect ground faults by monitoring the output from an external Core Balance Current Transformer (CBCT). It offers adjustable trip current and timing, LED status indicators, and supports Class A True RMS sensing per IEC 60947-2.
🔧 Technical Highlights:
- Supply Voltage : 220–415V AC
- Leakage Current Range: 30 mA to 30 A (via CBCT)
- Trip Time: 0–10 s adjustable
- Relay Output: 1 C/O + 1 NO
- Reset Modes: Manual / Auto / Remote
- LED Indicators: Power, Trip, CT Open, Earth Fault
- CT Monitoring: Detects open / shorted CT conditions
- Mounting: DIN Rail
✅ Benefits:
- Must be used with external CBCT (sold separately)
- Detects leakage faults with high accuracy and reliability
- Provides enhanced fire and shock protection in electrical systems
🚀 Applications:
- Low-voltage distribution panels
- Motor protection circuits
- Industrial and commercial power systems
This relay forms a complete leakage protection system when used with a compatible CBCT.
