Earth Leakage Relay

INR

An Earth Leakage Relay (ELR) is a protective electrical device used to detect leakage current flowing from electrical equipment to the earth. When the leakage current exceeds the preset limit, the relay activates and trips the circuit breaker to disconnect the power supply. This helps prevent electric shock, equipment damage, and fire hazards caused by insulation failure or wiring faults.
