Applications:
SFIN residual current circuit breaker without over-current protection conforms to standards of GB16916.1, IEC1008, and BC4293
Used in the circuit of AC 50-60Hz, single phase 230V, three phases 415V in industrial and mining enterprises, commercial building and housing for protection from electric shock hazard
Can be also used for circuits infrequent switchover under normal conditions.
When the circuit works normally, residual current operated circuit breaker is in on position, when leakage or electric shock occurs in the circuit, current transformer generates a signal to make electromagnetic release work, and cut off power source within 0.1 second to prevent leakage
