Residual current protection

Description

Electronic residual current protection relay, used to connect to the residual current transformers WG / WGC Series. These electronic relays offer a high reliability, with the option of a fixed or adjustable sensitivity and delay Type A relay with high frequency current filtering and high immunity. Monitoring of the true root mean square (TRMS).

• Assembly on DIN rail 46277
• Reduced size: 2 modules
• LED indicators:
  • Permanently lit leak indicator: LED Trigger relay
  • Flashing power LED and lit leak LED: detection of faults in the transformer’s continuity
  • Flashing leak LED indicator:
    • Leak with a value under the value selected
    • 1 flash every 2s: 25 ... 50% of the leakage current
    • 1 flash every 1s: 50 ... 75%
    • 2 flashes every 1s: 75 ... <100%
    • Permanently: 100 %

Applications

The relays of the RGE series and the transformer of the WG / WGC series enable a full residual current protection for both single and three-phase lines. They guarantee maximum security and continuity of the electrical service, avoiding unwanted tripping.
