MD0630T41A-1 Cable Type RCD AC DC Residual Current Transducer Monitoring Device for Power Distribution Unit

Charging of electric vehicles at a standard wall socket or a wall box requires protection devices against DC fault currents to avoid electric shock. Installed type A residual current circuit-breakers (RCCBs) are unable to identify and deactivate DC fault currents. IVY differential current sensors offer the opportunity to save the cost and space for a costly type B RCD in IC-CPD or wall boxes.

MD0630T41A-1 is an AC DC leakage current sensor, dual usage residual current monitor(RCM) with high sensitivity, mA level measurement, small size, integrated design, cable/horizontal installation. When the fault current reach the threshold, it can output the signal and cut off the circuit via a latching relay or break.

Product Details

MD0630T41A-1 is a Type B RCD/RCM. A device which monitors the residual current in an electrical installation and activates an alarm when the residual current exceeds the operating value of the device. It is able to withstand and properly function in the presence of a DC residual current component exceeding 6 mA. Type B leakage sensors made by IVY is widely used in GFCI, residual current device and other electrical safety protection device like EV Charging. These devices will issue an alarm signal when it detects that current is flowing along an unintended path, such as through water or a person. It is used to reduce the risk of electric shock, which can cause the heart to stop or cause burns. They can also prevent some fires, like when a live wire touches a metal conduit. MD Series RCD suitable for many industries including electric vehicle charger, photovoltaic systems, industrial device, medical device, new energy field, DC screen, power distribution unit, IOT field etc.
