MD0630T01A is a high sensititivity AC DC leakage current sensor for electric vehice charging station, which can also be called residual current sensor, residual current circuit breakers(RCCBs), residual current device(RCD), differential current sensor, leakage detection sensor, fault current sensor etc. To satisfy new standards including IEC 62955,IEC 62752, IEC 61851-1,and UL 2231-1 etc, the charging of electric vehicles requires leakage current sensors to avoid hazardous situations in cases where the vehicle battery(DC) is connected to the home power supply(AC).
Generally, AC DC Sensitive residual current sensors can be used where DC and AC circuits are directly connected and therefore AC DC leakage currents occur. This is new type of residual current monitor; it's based on the principle of magnetic modulation. it can be used to measure leakage currents including DC, AC, AC and DC, generally used as a DC leakage current detection and protection in equipment that uses DC operation. Used in electric vehicle charging pile (mode2 and 3 protection). Our MD series leakage sensor would be required to guarantee safety in the event of fault current.

Remarks and Notice
To satisfy new standards including IEC 62752, charging of electrical vehicles requires differential current sensors to avoid hazardous situations in cases where the vehicle battery (DC) is connected to the home power supply (AC).
Generally, AC/DC-sensitive differential current sensors can be used where direct current and alternating current circuits are directly connected and therefore AC/DC leakage currents can occur.
Typically, type A residual current circuit-breakers (RCCBs) are the sole type installed in private households, unable to identify and deactivate DC fault currents. Users seeking to charge an electric vehicle (EV) from a home power supply would therefore require a costly type B RCCB to guarantee safety in the presence of DC fault currents.
