A Leakage Current Relay is an electrical safety device designed to detect the presence of leakage currents in electrical circuits. Leakage current refers to the unwanted flow of electric current that escapes from an electrical system, typically through the insulation or other faulty components. This current can flow to the ground or unintended paths, posing risks such as electrical shocks, fires, and equipment damage.

    The relay works by continuously monitoring the electrical circuit and comparing the current flowing through the live wire to that flowing through the neutral wire. In a properly functioning system, the currents should be balanced. However, when leakage occurs, the current will be imbalanced, and the relay will detect this discrepancy. Upon detecting a certain threshold of leakage, the relay activates and disconnects the circuit to prevent further risks.
