MD0630T01A IEC62955 AC DC Leakage Detector Internal Type B EV RCD 6mA 30mA Residual Current Device

MD0630T01A is a residual current detection RCD, When an electric shock or leakage fault occurs in the circuit, the secondary side of the transformer outputs a mA level current (DC 6mA, AC 30mA), so that the equipment on the connected secondary line will be protected (cut off the power supply, alarm signal, etc.)

This RCD module detects DC currents flowing in an AC system. For example, in electric vehicle charging stations or from solar panels. DC currents flowing in an AC system may cause a Type A RCD or a Type F RCD to be blinded. This RCD module can be used to detect any DC current level above 6mA and its output can be used to operate a relay or a contactor to disconnect the AC supply, and display an error message on the screen of EVSE system, and wait for a user to reset the error.

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!
