Product Introduction
MD0630T01A is a high sensititivity leakage detection device which has the characteristics of accurate measurement, small size and integration. The leakage sensor can be set separately for AC and DC leakage. An alarm signal is generated when the set current is reached. The leakage sensor has a digital output function, which can directly read the current value of DC and AC. Which can also be called residual current sensor, residual current monitor (RCM), residual current device (RCD), differential current sensor, earth leakage detector and fault current sensor etc. 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.
MD0630T01A 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.
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.
Use type B RCD, which is suitable for AC and DC fault protection.
Use type A RCD and a DC 6mA sensor to provide a means of disconnection of supply in case of DC fault.
IVY type B RCD(type A + 6mA dc) enables compliance with the updated BS7671:2018 and reduces the cost of developing electric vehicle charging solutions, which is more cost-effective than using a Type B RCCB.
