IT Distribution System Residual Current Relay
This relay measures A-type residual current and displays the current percentage. It also allows setting of rated residual action current and non-driving time limitation.
Technical Specifications
Overview
Advanced Residual Current Protection
This residual current relay is engineered for TT and TN electrical distribution systems operating at 400V or below. It provides critical earth fault protection, effectively preventing equipment damage and mitigating fire risks caused by ground fault currents. Additionally, the device offers essential indirect contact protection to enhance safety against electric shock risks in both industrial and commercial environments.
