The application of TypeB leakage current sensor in charging piles has the following advantages:
- The measurement range is ± 500mA, providing a better choice for the development of charging pile leakage protection. 
- The residual current sensor can achieve residual current detection function, using the principle of magnetic flux gate, and has advantages such as high accuracy and low temperature drift. 
- It can be used in conjunction with B-type leakage current sensors in three-phase AC charging stations. 
- Can be applied to electric vehicle IC-CPD, WallBox, charging pile leakage current monitoring, photovoltaic inverters, UPS, etc.
