Pin Definition

Why is RCD required in IC-CPD and AC Charger applications?

The existing type A RCD can only in the detection of pulsating DC leakage from 6 mA DC 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, resulting in tripping value deviation, leading to the type A RCD can’t normal movement. 

Therefore, type B RCD or A+6mA protection must be used!

FAQ

What is an AC DC leakage sensor for EV chargers?

An AC DC leakage sensor monitors residual current faults in EV charging systems. It detects both AC leakage and smooth DC leakage currents to improve electrical safety and prevent RCD protection failure.

Why do EV chargers need 6mA DC leakage detection?

EV chargers contain power electronics that may generate smooth DC residual currents. Traditional Type A RCD devices may lose sensitivity when DC leakage exceeds certain levels, so IEC 62955 requires DC leakage detection for EV charging protection.

What standards does MD0630T01A comply with?

MD0630T01A supports EV charging protection requirements including IEC 62955, IEC 62752 and IEC 61851-1 related applications.

What is the difference between Type B RCD and MD0630T01A?

A Type B RCCB is a complete protection device, while MD0630T01A is a compact residual current monitoring sensor designed for integration inside EV chargers and electronic systems.
