INFORMATION

Description

Electronic industrial residual current protection relay, compatible with the WGC series protection transformers.

Ultra-immunised type-A relay, with high-frequency current filtering and high immunity. True root mean square (TRMS) measure.

  • Programmable with backlit LCD display:
  • Sensitivity and trip time
  • Output contact status.
  • Protection status messages.
  • Real-time level of leakage.
  • LED bar showing the percentage leakage current measured by the unit.
  • Features two independent programmable outputs (main and prealarm / relay fault).
  • Assembly on DIN 46277 rail (EN 50022), 2 modules.
  • Locking the programming menu with the keyboard or by sealing the PROG button.
  • RCM and MRCD in the same unit (see connections)

Applications

The RGU-2 relays associated with WGC transformers offer smart and robust residual current protection against all types of unwanted tripping. Since these residual current relays only take up 2 modules of space, include an LCD display, a bar LED and are fully programmable, they are essential for protecting people and for preventive maintenance of the installations.
