circuit breaker for car charger is with type B + 6mA DC Leakage Protection. In the case of electric passenger vehicles, the place of charging is mainly the place of residence. To ensure the safety of charging, many vehicle manufacturers need protection against DC 6mA leakage. However, normal fault current circuit breaker cannot achieve DC 6mA detection. DIHOOL But the special type B +DC 6mA fi circuit breaker is compatible with type B and DC 6mA leak protection systems. It can guarantee its safety. Reason for DC Leakage Detection: For charging electric vehicles, a residual current monitor is required to detect leakage to avoid the potential danger of the car battery (DC) being connected to the main power supply (AC). The DC component generated during the charging process of charging stations or control boxes can affect the quality of the power grid, and DC leakage can also pose a risk of arcing the electrical equipment itself. If I is in charging station D,causes a smooth DC leakage current of n DC ≥ 6 mA interference in the response time and sensitivity of B-type leakage protection (RCD) during long-term charging (high conductivity magnetic ring generates magnetic offset under the influence of DC). Due to the inability to detect such leaks, the protection threshold of the TypeB leakage current sensor is unreliable. To prevent error detection, it is possible to replace the charging station
