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
