Product Details
MD0630T41A is a cable&pcb mount AC DC leakage current sensor, which can also be called residual current sensor, residual current monitor (RCM), residual current device (RCD) and differential current sensor. It can detect DC and AC residual currents in 50Hz/60Hz AC installations according to IEC62955. It's primarily intended for use in Electric Vehicle charging stations to disconnect the supply to the Electric Vehicle under a DC residual fault current condition. It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs.
In electric vehicle charging if the DC fault current is greater than 6mA, it could change the characteristics of a Type A RCD due to its core saturation, resulting in the type A failing to trip and a lack of detection of the DC fault. In this instance, the risk of electric shock is increased, and safety is compromised. IVY has launched a new RCD sensor that is designed to detect a DC earth fault, which is more cost-effective than using a Type B RCCB. In the event of a dangerous electrical fault, the sensor will output an alarm signal (by setting the leakage alarm value). This new RCD sensor enables compliance with the updated IEC62955:2018 and reduces the cost of developing ev charging solutions.

Product Applications
By using a IVY MD series RCD sensor integrated into an IC-CPD or wall box, customers can save the high costs of installing a type B RCCB to provide all-current sensitivity and electrical safety at low cost. As the residual currents to be monitored only occur in the event of electrical faults and are extremely low (mA), maximum measurement precision is critical. In addition, a fast response time is required to maintain safety features.
