Description
The residual current intensity monitoring and protection relay (IEC 62020) is compatible with the WGB series, designed for type B loads (IEC 60755), and includes 4 fully independent channels.
Main Features and Functions
- Electronic relay with relay output (up to 4 channels)
- Measures in alternating, continuous, or mixed current (Type B according to IEC 60755)
- Displays the current intensity of each of the 4 channels independently, via connection to the WGB-series residual current transformer
- Fully programmable with a high-contrast backlight display showing real-time leakage current (display turns red when the relay trips)
- Integrated RS-485 (Modbus) communications
- Pre-alarm relay
- Event log
- Remote control input
Applications
Suitable for residual current protection or monitoring of single-phase or three-phase electrical loads in alternating current with continuous components, with frequencies up to 2 kHz, such as:
- Variable speed drives
- UPS
- Photovoltaic installations
- Electric vehicle charging
- Active filters
