RefleX 1505 - Overcurrent, Directional EF, Phase-Unbalance and Autoreclosure relay
 


   
This relay includes a 3-phase Overcurrent module with 2 separate current/timer levels, a Directional EF module with two current/timer levels and a negative sequence measurement module for Phase-Unbalance detection.
The common Autoreclosure module can be programmed freely for 1...6 shots, or completely disabled (not appearing in the menu). 
The relay is extremely well suited for distribution power lines in systems with high resistance neutral grounding. In cable networks the Autoreclosure should be disabled.
