ChinSun is a professional High Voltage Transformer Bushings manufacturer from China. ChinSun is a professional High Voltage Transformer Bushings manufacturer from China. MCCB with Earth Leakage Protection(ELCB) TRE Series
Independent power supply with build-in power source,directly draws power from the incoming end to avoid the risk of protection function failure caused by external power supply failure.
Earth-leakage protection is a residual current protection based on current measured by a rectangular sensor encompassing the three phases of the three phases and neutral.
