A phase failure relay continuously monitors the voltage levels of a three-phase power supply. If it detects any abnormal conditions—such as one phase failing (open phase), incorrect phase sequence, or significant voltage imbalance—it activates a relay to disconnect the load, preventing equipment damage.
Key Features:
* Phase Loss Detection: Detects when one or more phases are lost or disconnected.
- Phase Sequence Monitoring: Ensures the correct rotation of phases to protect motors from running in reverse.
- Voltage Imbalance Detection: Monitors for unbalanced voltage conditions that can cause motors to overheat.
- Under/Over Voltage Protection (Optional): Some models also protect against voltage drops or surges.
- LED Indicators: Shows status like phase presence, fault, and relay output state.
- Compact Design: Easy to install on DIN rails in control panels.
- Auto/Manual Reset: Options available depending on the application.
- Wide Voltage Range: Can operate with different voltage levels like 200-480V AC.
