Asymmetry relays
Asymmetry relays for 3/N AC systems
The asymmetry relays are designed for monitoring voltage unbalances in three-phase systems.

 |
The relay of the AUR381Z series is designed to monitor 3(N)AC systems for asymmetry, undervoltage and phase failure.External supply voltage is not required. The internal supply voltage is electrically isolated from the system. Special input transformers attenuate of interferences from the system. An integrated protective circuit is provided for use in systems with interferences. |
