Earth Leakage Relay(MSBRR)
Operations: The tripping device of the relay will operate if the leakage current either in the circuit or in the electrical apparatus exceeds its rated sensitivity.
It will not operate if the leakage current is smaller than 50% of its reted sensitivity value.
Connection example of earth leakage relay and MCCB, magnetic motor starter or buzzer.
Rated voltage: 240v
Rated tripping current: 300mA
Rated tripping time below: 0.1s
