LGL7 (F7) leakage circuit breaker RCCB RCBO RCD
The zero phase current transformer of earth leakage protection switch is used for examining
the current vector difference value which flows through the zero-phase current transformer
meanwhile a relative output power produced on the secondary winding of zero-phase current
transformer is added to the earth leakage trip,when earth leakage of hazard occurs in the
protected circuits only leakage current of electric hazard current reaches or exceeeds or
exceeds leakage operating current,the earth leakage trip may operate and make the switch to
break the fault circuit thus the protection for hazard is realized.Residual current circuit breaker
standards of GB16916.1-2003.IEC1008ETC.
