What is a Earth leakage relay?

A leakage relay is a protective device used to detect leakage currents in electrical equipment. Leakage occurs when current flows improperly due to insulation failure or other issues in electrical equipment. The leakage relay detects this leakage and automatically disconnects the circuit to prevent fires and electrical shocks. Typically, leakage relays are adjustable for sensitivity and are designed to disconnect the circuit when the leakage current exceeds a certain threshold. This ensures safety by protecting both the equipment and individuals from potential hazards.

Application of Earth leakage relay

１．Household electrical devices: Installing leakage relays in household appliances like air conditioners and washing machines to automatically shut off the device in case of leakage.
２．Industrial machinery: Installing leakage relays in factory machines and power tools to ensure safety.
３．Power supply equipment: Installing leakage relays in high-voltage power equipment to prevent fires or accidents caused by leakage.
