Product Details

MD0630T41A-1 is a high sensititivity ac dc leakage current sensor for electric vehice charging station, It has the characteristics of high sensitivity, correct measurement, small size and compact/integration design. The leakage current sensor can be set separately for AC and DC leakage. When leakage current is detected, an alarm signal is generated. Which can also be called residual current sensor, residual current monitor (RCM), residual current device (RCD), differential current sensor, zero phase current transformer and fault current sensor etc. “Residual current” refers to the leakage current from an electrical system to the ground, often as a result of a “ground fault”. Leakage currents can flow through a human body to ground resulting in a risk of electric shock, injury or burns, and can cause overheating and risk of fire. 


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. Zero phase current transformer Type A/ Type B 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, fire distribution cabinet, IOT field etc.
