The MD-PR380A3P3W Air Conditioning Protect Relay is a three-phase protection relay designed for air conditioners and HVAC systems. It provides complete protection against power anomalies such as phase failure, phase sequence errors, over/under voltage, and phase imbalance, ensuring stable operation and extending equipment life.
- Wide Voltage Range – Monitors 3-phase AC power (generally 380V, 50/60Hz).
- Full Protection – Guards against phase loss, phase reversal, over/under voltage, and unbalanced voltage.
- HVAC-Specific Design – Optimized for protecting compressors and motors in air conditioning units.
- Automatic Reset – System restarts automatically when voltage returns to normal.
- Delay Protection – Adjustable delay avoids nuisance trips during transient fluctuations.
- LED Status Indicators – Clear visual display for power and fault conditions.
- Compact & Reliable – Easy integration into control panels with robust performance.
