INFORMATION

Description

The residual current transformers of the WGB range are especially designed to protect and monitor B-type loads (IEC 60755), and are suitable for measuring AC, DC and pulsating leakage currents.

The range of WGB differential transformers is designed for use with the RGU-100B or CBS-400B electronic relays, which give them the associated trip current (sensitivity).

The transformers have an Ethernet port to connect them using this type of cable with the relay, which transmits all the readings and other information on the protected or monitored line.

Applications

Residual current protection or monitoring of single-phase or three-phase electric loads in alternating current with direct current components, with frequencies of up to 1 kHz, such as:

  • Variable speed drives.
  • UPS.
  • Photovoltaic Facilities.
  • Electrical Vehicle Charging.
  • Active filters.
