phase protection/ 3 phases voltage relay/ phase failure

Specifications Phase relay, phase failure, phase reversal, phase loss protection, over-voltage and under-voltage protection

1. Over-voltage and under-voltage protection: When the power supply voltage is too high and too low, it will be cut off and over-voltage and under-voltage value can be set up 2. Phase loss/failure  protection 3. Phase sequence protection: when there is an error with the three-phase power, power supply will be cut off 4. It is small and SMT technology is used, with reliable quality and stable performance 5. It can be installed on a standard guide or screw 6. Suitable voltage range 140~580VAC/200~500VAC 7. Selecting the appropriate contact material according to different inductive load and resistive load     Technical Parameters:
