Earth Leakage Relay

Leakage relay is used to detect whether there is leakage in the line and equipment. Once the leakage occurs, it will automatically trip and cut off the power, which can prevent the leakage of the wire and equipment, or the electric shock accident caused by the process of using electricity, and avoid the fire accident caused by the leakage. Leakage breaker is one of the line protection devices. There is an experimental button on the product. You should test it regularly to avoid failure of the leakage relay and so on.
