The high-performance residual current monitoring and protection relay, compliant with IEC 62020, is specifically designed for Type B loads (as per IEC 60755) and offers seamless compatibility with the WGB series current transformers. This advanced electronic relay features precise measurement of alternating, direct, or mixed currents, and provides real-time display of leakage current on a high-contrast backlit screen that turns red upon tripping. It includes a relay output, a pre-alarm function, an event log, and remote control input for enhanced system integration. With fully programmable settings and integrated RS-485 Modbus communication, this relay ensures reliable protection and monitoring in demanding electrical installations.
