Leakage protector, also known as a leakage switch or leakage circuit breaker, is primarily used for protecting against leakage faults in equipment and for safeguarding against potentially fatal electric shocks to people. It also protects electrical equipment against overvoltage and provides overload and short-circuit protection, which can be used to guard against overloads and short circuits in lines or motors. Additionally, it can be used for infrequent switching and starting of lines under normal conditions.
