:circuit breaker 1:Application 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. 2:Use and maintenance I:Ambient air temperature ambient air temperature ranges from -10°C 40°C not exceeding 35°C averagely in 24hours.
