Product Details
Residual current devices (RCD) type A and type B and the residual current leakage monitor (RCM) type B are designed to protect people from electric shock when touching them, both directly and indirectly. In accordance with the PN-EN IEC 61851-1 standard, each charging point must be protected by overcurrent and residual current circuit breakers type A + B. The use of a type B residual current leakage monitor inside the station facilitates. MD0630T41A-1 is a small device installed inside the charging station equipment to detect whether there is a DC fault in the car battery. If a fault is detected, it outputs an alarm signal and the auxiliary contactor/relay cuts off the power. This protects your equipment from incoming DC surges.
It is suited for AC/DC residual current measurement, identifying AC and DC residual (earth fault) currents in combination with charge controllers and residual current monitoring modules.This sensor is practical and more cost effective for integrators to use and install into charging solutions. It measures currents in accordance with IEC62955, ensuring safe, compliant charging. In addition to the use of charging piles. Also suitable for medical instruments, solar inverters, UPS, DC panels, smart home, industrial machines, IOT, power distribution cabinet etc. Protecting personal and electrical equipment safety.

What is IEC 62955 DC 6mA leakage current protection?
IEC 62955 - Residual direct current detecting device (RDC-DD) to be used for mode 3 charging of electric vehicles. This International Standard applies to residual direct current detecting devices (RDC-DD) for permanently connected AC electric vehicle charging stations (mode 3)
MD0630T41A-1 is a type B RCD/RCM sensor, which are used where DC residual currents could occur, in addition to normal AC, can detect high-frequency AC and pure DC earth leakage currents. The tripping conditions are defined with different frequencies from 50Hz to 1kHz. Reducing the risk of fire or electrocution through output digital alarm signal. MD series Type B RCD is an ideal protection device against different leakage currents in applications of electric vehicle charging, photovoltaic systems (solar panels), industrial device, medical device, new energy, DC screen, fire distribution cabinet, IOT field etc.
