Item No.: LYL9 A+EV

Key Specifications：

Scope of application
LYL9 type A+EV leakage current circuit breaker is suitable for protection of Ac facilities with charging mode 3, Dc leakage current of morethan 6mA .when there is a residual fault current of more than 6mAin the system,it can automatically cuts off the fault power in very short time.
It is used to detect the DC residual current greater than 6mA in the Ac system. According to the lEC61851 standard, it should be used with the RCD with type A residual current protection characteristics,which provides protection again stpossible ground faults.

The LYL9-AEV RCCB is a residual current circuit breaker optimized for applications involving electric vehicle charging and modern electronic loads.

FAQs

1. What makes LYL9 A+EV RCCB special?
The LYL9 A+EV circuit breaker is designed to detect both AC and DC leakage currents, such as those found in modern charging systems (Mode 3 EV chargers), offering enhanced safety where DC leakage can occur.

2. Why is DC leakage detection important?
DC leakage currents (greater than ~6 mA in AC systems) may not be detected by traditional AC RCCBs, so devices like this ensure comprehensive fault detection in mixed AC/DC environments.

3. What safety standards are relevant for this type?
This type of RCCB is used in accordance with IEC standards such as IEC 61851 for EV infrastructure leakage protection.

4. Where is this breaker typically applied?
Ideal for applications involving electric vehicle charging stations, battery systems, and renewable energy interfaces where DC components are present.

5. Is OEM or bulk supply supported?
Yes. We are a professional RCCB manufacturer and supplier offering OEM customization, bulk order capability, and tailored solutions.
