Product Overview
MD0630T01A is a high sensititivity AC DC leakage current sensor for electric vehice charging station, which can also be called residual current sensor, residual current monitor (RCM), residual current device (RCD), differential current sensor, leakage detection sensor, fault current sensor etc. This residual current monitor will 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.
MD series residual current sensor (RCD/RCM) is an ideal protection device, for the detection and protection of different leakage currents/residual currents/fault currents. The RCD could quickly output alarm signal when people get an electric shock or leakage current exceeds stipulated value, protecting personal and electrical equipment safety.
AS a Type B RCD, MD series leakage sensor have numerous applications and are suitable for many industries including electric vehicle charging, photovoltaic systems (solar panels), industrial device, medical device, new energy, DC screen, fire distribution cabinet, IOT field and any installation where there is a risk of DC current flowing. It is the technology that brings us closest to total protection for all known residual fault currents.

FAQ of Leakage Sensor:
Q1:what is this?
A:It's an EV type residual current monitor, providing leakage protection for Mode2/Mode/3/Mode4 charging and complying with the requirements of the relevant standards for leakage protection in the European market.
Q2:How does this work?
A:Smoothed DC residual currents can occur in certain power electronics applications. Smoothed DC residual currents can prevent conventional AC-type and type A residual current protection devices (RCDs) from functioning properly, with RCD inactivity or normal operation malfunction in the event of an electric shock. EV charging is a typical load that can generate a smooth DC residual current component and for effective personal safety protection, the IEC 62955 standard provides for the protection of possible smooth DC residual currents from EV charging. It effectively eliminates the loophole of AC 30mA residual current protection caused by smooth DC residual components and effectively disconnects the conductive part, making it far safer and more reliable than the combination of residual current monitoring module and relay on the charging post board.
Q3:Why do AC charging posts generate smooth residual currents?

Q3:Why do AC charging posts generate smooth residual currents?
A:The main reason is that the insulation of that part of the DC/DC inside the OBC is broken, which can be caused by driving the car for a long time, bumps and bumps, careless maintenance, etc., and then smooth DC residual current will be generated.
Q4:Why choose it?
Q4:Why choose it?
A:This product combines 6mA DC monitoring, detection and 30mA Type A residual current protection in one device. It offers the following advantages: Safe and reliable Integrates multiple protection against short circuit, overload, residual current (sinusoidal AC, pulsating DC and smooth DC faults) in one device; the neutral pole can be opened and closed to cut off both the fire and zero wires in the event of a fault, making the charging process safer.
