Product Introduction
A Residual Current Device is a sensitive safety device that switches off the electricity within 10 to 50 milliseconds if there is an electrical fault. An RCD is designed to protect against the risks of electrocution and fire caused by earth faults. The MD0630T01A is a high-sensitivity leakage current sensor that is known as a residual current monitoring sensor capable of detecting AC 30mA & DC 6mA residual currents. It features a digital fault output and UART communication. It can be used to construct an IEC 62955-compliant Residual Direct Current Detecting Device (RDC-DD). This setup fulfils the residual current protection requirements specified in IEC 61851-1.
The higher-level safety equipment (RCD sensor) is protected against potential DC residual currents. MD0630 series is practical and more cost-effective for integrators to use and install into charging solutions, primarily intended for use in Mode 2 (IC-CPD) and Mode 3 Wallbox. The MD0630T01A is a compact solution designed to be mounted directly onto a PCB. Allows the protection of EV chargers. Besides, it's widely used for solar panels, heat pumps, medical instruments, inverters, battery packs, UPS, industrial machines, and power distribution units(PDU), etc.

Why do IC-CPD and AC charging station (Wall-Box) applications require DC 6mA detection capabilities or the use of Type A/Type B RCDs?
Standard Type A RCDs can only detect pulsating DC leakage; they are unable to detect and trip in response to DC leakage exceeding 6mA. This is because DC residual current causes pre-magnetization of the magnetic core, leading to a shift in the tripping threshold that prevents the Type A RCD from operating correctly. Consequently, a Type B RCD or a "Type A RCD + 6mA protection" solution must be used. IVY’s MD0630T01A is specifically designed for AC and DC electrical installations and EV charging applications, providing monitoring, electric shock protection, and fault protection functions.
