RefleX 1506 - Overcurrent, overvoltage and undervoltage protection
 


   
This relay includes a 3-phase Overcurrent module with 3 separate current/timer levels, a 3-phase overvoltage module with 2 separate voltage/timer levels and 3-phase undervoltage module with 2 separate voltage/timer levels.  The relay is well suited as an overcurrent protection for transformers in combination with bus voltage protection or bus earth fault protection. The overvoltage function has a wide setting range well suited as a voltage earth fault function.
