Product Details

Designing modern power electronics requires space-saving and cost-effective safety solutions. An integrated RCD (Residual Current Device) provides built-in leakage protection directly on your PCBA, eliminating the need for bulky and expensive external circuit breakers. Ideal for EV chargers (Wallboxes and IC-CPD), smart sockets, and industrial controls, an advanced Type B integrated RCD module accurately detects hazardous AC (30mA) and smooth DC (6mA) leakage currents. By choosing a highly compact integrated RCD solution, manufacturers can significantly reduce system dimensions, streamline the assembly process, and ensure full compliance with strict electrical safety standards like IEC 62955.

MD0630T41A-1 is an automotive-grade leakage current sensor also 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.

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.
