Product Details
MD0630T41A-1 is a zero phase leakage current transformer sensor(also called RCD/RCM). It is intended to detect dangerous 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 technology used has the ability to detect AC and DC residual currents. It has the characteristics of high sensitivity, correct measurement, small size and compact/integration design. The residual current device can be set separately for AC and DC leakage. When leakage current is detected, an alarm signal is generated, and the switch control signal is output at the same time.
It is designed for use in e-mobility infrastructure and AC charging station designs to monitor leakage currents in mode 2/3 electric vehicle charging. It is supplied as either direct PCB mount or cable harness connection. It is suited for AC/DC residual current measurement, identifying AC and DC residual (earth fault) currents. They are the relevant IEC product standards protective devices for use in Mode 2, Mode 3 and Mode 4 EV charging. Residual current detection options for IEC based requirements are 30mA AC or 6mA DC, It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs.
This new current sensor is practical and more cost effective for integrators to use and install into charging solutions. It measures currents in accordance with IEC 62752 and 62955, ensuring safe, compliant charging. It is an ideal protection device, for the detection of different leakage currents in applications of DC screen, Fire distribution cabinet, PV inverters, medical equipment, UPS devices, EV charging facilities etc.
