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. IVY MD0630T01A rcd sensor is an automotive grade high sensitivity leakage current sensor also called residual current monitoring (RCM), residual current detection (RCD), differential current sensor, and fault current sensor. It is specifically developed for EV charging providing all-current sensitivity. It can be set separately for AC and DC leakage and has a digital alarm output function. The MD0630T01A can monitor DC (6mA) and AC (30mA) residual currents.
The higher-level safety equipment (residual current monitor) is protected against potential DC residual currents. MD0630 series are 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, ventilation, medical instruments, inverters, battery packs, UPS, industrial machines, and power distribution units(PDU), etc.

Why a DC 6mA or a Type A/B RCD been required in IC-CPD and AC Charger/Wall-Box application?
The existing type A RCD can only in the detection of pulsating dc leakage from 6 mA dc current interference, and can’t detect dc leakage and disconnect protection, when DC leakage is more than 6 mA, due to the DC residual current will cause core magnetization in advance, make tripping value deviation, lead to type A RCD can’t normal movement. Therefore, type B RCD or A+6mA protection must be used! IVY offers MD0630T01A for monitoring and/or providing shock protection and fault protection on AC and DC installations and for EV charging applications.
