4 channels residual current relays, type B, 3 modules

Description

The residual current current intensity monitoring and protection relay (IEC 62020), compatible with the WGB series, for type B loads (IEC 60755) and with 4 totally independent channels.

High-performance relay with the following 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)
• It measures and displays the current intensity of each of the 4 channels independently, through the connection to the WGB-series residual current transformer.
• Fully programmable with display showing instantaneous leakage current in real time on a high-contrast backlight display (display turns red when the relay trips).
• Integrated RS-485 (Modbus) communications
• Pre-alarm relay
• Event log
• Remote control input.

Applications

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
