Microcontroller Based Earth Leakage Relay operates on a power supply rate of 220V at the frequency rate of 50Hz. The Earth Leakage Relay is a microcontroller based safety tripping device that can prevent electrical loss and life loss. The Earth Leakage Relay functions with SMD technology to ensure optimum performance for longer period of time. Microcontroller Based Earth Leakage Relay can function in different temperature ranges varying from 0 Degree C to 70 Degree C.
