A Leakage Current Relay is an essential safety device in modern electrical systems, designed to detect and prevent the risks associated with leakage currents. These currents occur when an unintended path for electricity is formed, often leading to electrical shock hazards, fire risks, or equipment damage. Leakage current relays are critical in protecting both individuals and machinery from these dangers, and their importance cannot be overstated, especially in environments where electrical safety is paramount, such as in residential, industrial, and healthcare settings.

What is a Leakage Current Relay? A Leakage Current Relay is a protective device that detects the presence of leakage current in an electrical circuit. Leakage current refers to the small amounts of electrical current that escape from the normal flow of electricity, typically due to damaged insulation or faulty electrical components. While these currents may seem minimal, they can be dangerous if left unchecked, especially in high-voltage systems or sensitive environments. These relays are designed to monitor the amount of current flowing in the system and immediately disconnect the power supply if the leakage current exceeds a predefined threshold. This action prevents potential electric shocks, fires, and damage to electrical devices.
