INFORMATION

Description

The WGBU Series is a compact residual current protection system. It is composed of a toroidal transformer with a built-in residual current relay.

  • Multi-range electronic relay
    • The sensitivity can be adjusted to 0.03 ... 3 A
    • Trigger delay of 0.02 ... 1 s, adjustable
  • Type A relay with high frequency current filtering and high immunity. Monitoring in true root mean square (TRMS).
  • LED indicators:
    • Grid connection LED
    • Pre-alarm and trigger LED: 1 flash every 2 s, leak between 25 and 50 % of the sensitivity selected; 1 flash every 1 s, leak between 50 and 75 % of the sensitivity selected; 1 flash every 0.5 s, leak exceeding 75 % of the sensitivity selected; permanently lit, trigger of the residual current protection.

Applications

The WGBU series offers a reliable residual current protection, with simpler cabling and savings in the assembly time. In addition, installation is very simple, thanks to its compact dimensions.
