Product Details
MD0630T41A-1 is an automotive grade leakage current sensor also be called residual current monitoring (RCM), residual current detection (RCD), and differential current sensor. It has the characteristics of high sensitivity, correct measurement, small size and compact design. The residual current monitor can be set separately for AC and DC leakage. When leakage current is detected, an alarm signal is generated. It is intended to detect dangerous A-type B-type residual currents and thereby mitigate the risk of electric shock or fire.
In the case of EV charging, there is a risk of AC and DC residual currents, and it is vitally important that the RCD can be used to detect AC and DC residual currents. It can monitors DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE, if a fault occurs. In addition to normal AC, it can detect high-frequency AC and pure DC leakage currents. Suitable for many industries including electric vehicle charging, solar panels, industrial equipment, medical device, DC screen, power distribution cabinet and any installation where there is a risk of DC current flowing. It is the technology that brings us closest to total protection for residual fault currents.

EV Charging Application
Where the EV supply equipment is equipped with a socket-outlet or vehicle connector for AC use in accordance with IEC 62196(all parts), protective measures against DC fault current shall be taken. The appropriate measures shall be:
Type B RCD or Type A RCD and appropriate equipment that ensures the disconnection of the supply in case of DC fault current above 6mA
In the IEC 61851-1, it is clearly specified that residual current protection in AC charging equipment shall adopt type B or type a +6ma smooth DC RCD. At the same time, it is clearly stated in the relevant IC-CPD standard IEC62752-2018 that the residual current protection device shall detect smooth DC 6mA.
