Description
GYL9 type A+EV leakage current circuit breaker is suitable for the protection of AC facilities with charging mode 3, DC leakage current of more than 6mA. when there is a residual fault current of more than 6mA in the system, it can automatically cut off the fault power in a very short time. It is used to detect the DC residual current greater than 6mA in the AC system. According to the IEC61851 standard, it should be used with the RCD with type A residual current protection characteristics, which provides protection against possible ground faults.
