The SJ fault indicator is applied to 10kV power distribution system. When there is a short circuit fault or single phase earthing problem, the indicator can automatically locate the fault circuit or fault phase. Thus the labor intensity could be reduced and the power supply reliability can be enhanced.
Rated voltage: 12kV
Rated current: 630A
Suitable wire cross sectional area: 35～240mm2
Ambient temperature: -40℃～+65℃
